Although it attracted the attention of the industry with its generous and \"never giving up manufacturing\" attitude, it continued to be controversial because of its poor financial report;</p><p>Yesterday, four senior Intel manufacturing technology experts, including CEO Kissinger, once again disclosed Intel's process technology and implementation path on a large scale.<b>A \"new bomb\" was dropped on the semiconductor industry:</b></p><p><ul><li>Intel does have delays at 10nm and 7nm (if you are interested, you can read my article \"Intel Abdicates, TSMC Becomes King\"), but on the 5nm node, Intel believes that instead of delaying, it will complete the transcendence.</p><p></li></ul><ul><li>In order to deal with the \"false propaganda of manufacturing processes\" by rivals such as TSMC and correct everyone's misunderstanding of manufacturing processes, Intel directly abandoned the statement of \"10nm, 7nm, 5nm, 3nm\" that is essentially determined by Moore's Law, and directly adopted 100% Intel's new naming system from a subjective perspective-Intel7, Intel4, Intel3, Intel20A, Intel18A.</p><p></li></ul><ul><li>The Intel20A disclosed this time essentially corresponds to the 5nm process.<b>This is a manufacturing process node that Intel has kept silent about for the past two years, and the relevant time plan basically ended abruptly at 7nm. Intel</b>It was announced for the first time that it would enter the \"Amy Era\" through Intel20A.</p><p></li></ul><ul><li>The two key technologies behind Intel20A are very noteworthy. Among them, this process will use a new transistor structure Gate-All-Around, which is not a FinFET structure that has made great contributions to the productization of processes below 22nm.</p><p></li></ul>In other words, this new structure chip using new materials will bring about major changes to the traditional process concept. Just like a semiconductor technology expert told Tiger Sniff: \"This new material structure and the manufacturing process are a few nanometers or so, it doesn't matter so much.\"</p><p><b>Intel's new process naming system: Wake up, customers</b></p><p>The naming of the manufacturing process has been criticized by the industry for a long time.</p><p>For example, we once mentioned in the article \"Intel Abdicates, TSMC Becomes King\" that many engineers in the industry believe that Intel has a more realistic attitude towards \"nano\" process numbers, and even said that \"Intel's 10nm chip benchmark is actually TSMC's 7nm, even better than the latter's 7nm.\"</p><p>This is why Kissinger has repeatedly called on everyone to correctly understand \"process numbers\" in public after taking office:</p><p>\"Including Intel, different process node naming and numbering schemes are used. These schemes neither refer to any specific measurement method nor fully demonstrate how to achieve the best balance of chip energy efficiency and performance.\" This is like those cars at auto shows that claim to have reached hundreds of thousands of Tops in their chips, and it is also like the \"Autonomous Driving Takeover Report\" released by California every year-without uniform test conditions and sufficient corporate integrity, it is absolutely unworthy of saying \"Who performs better than whom\" conclusion.</p><p>Therefore, Intel has made great efforts to change the naming system this time, saying: \"Let customers have a more accurate understanding of the evolution of process nodes in the entire industry, and then make more informed decisions.\"<b>In fact, the main purpose is to deal with the less reliable 5nm and 3nm process names of TSMC and Samsung.</b></p><p><ul><li>The Intel 7, which will be launched in the second half of 2021 (does it at least look like 7nm?), is actually the 10nm Enhanced SuperFin previously released by Intel;</p><p></li></ul><ul><li>The Intel 4 released in the first half of 2023 (at least it looks like 4nm?), is actually the 7nm of Intel's previous PPT;</p><p></li></ul><ul><li>The Intel3 released in the second half of 2023 is actually the 7nm + on Intel's previous PPT;</p><p></li></ul><ul><li><b>Intel20A released in the first half of 2024 (does it look like 2nm?), is actually 5nm under Intel standards;</b></p><p></li></ul><ul><li>Intel18A will be released in the first half of 2025, which is actually 5nm + under Intel standards.</p><p></li></ul><img src=\"https://static.tigerbbs.com/1ce380fc9b07caca9a43fa165a2e90a8\" tg-width=\"1000\" tg-height=\"471\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image via Intel</p><p>In fact, with the increasing complexity of transistor structures, as early as the beginning of the 21st century, the industry began to have a \"differentiation trend\" in the naming of nanometer processes of chips.</p><p>As we all know, microprocessors are made up of billions of transistors connected in a specific way. These transistors act as \"switches\" and are responsible for processing the ones and zeros of electronic data.</p><p>Kissinger explained that there is an area at the top of the transistor called the \"gate\", which determines whether the transistor is turned on or off. The \"process node\" refers to a complex scheme consisting of thousands of manufacturing steps required for transistors.</p><p>And almost all the top semiconductor companies have the same goal-to make these chips smaller, faster, cheaper, and more energy-efficient-the best example is Apple's 5nm process chip M1 (there are too many reviews about M1 You can see the review, I also bought an M1 Macbook Air, and I can't put it down).</p><p><img src=\"https://static.tigerbbs.com/ae99fc8b1663fb184dc959320da5b5a1\" tg-width=\"1000\" tg-height=\"384\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Initially, the name of the process process \"node\" corresponded to the gate length of the transistor and was measured in \"microns\".<b>As transistors became smaller and smaller, the length of gates became smaller and smaller, and the industry began to measure it in nanometers.</b></p><p>The key node about the change of process naming appeared in 1997.</p><p>\"With technological advances and the emergence of other innovative technologies such as strained silicon, faster, cheaper and more energy-efficient becomes equally important in addition to shrinking transistors.\" Kissinger believes that from this point on,<b>Traditional naming methods no longer match the actual transistor gate length.</b></p><p><b>In other words, transistor size is not the only determinant to some extent, and factors such as the \"interconnection\" between them cannot be ignored.</b></p><p>In 2011, after Intel launched FinFET transistor structure technology, the industry was further differentiated. It's an entirely new way to build transistors, with unique shapes and structures.</p><p>This structure is the key technology to continue to indent the stagnant 22nm.<b>But it must be clear that starting from 22nm, not to mention the public, even the industry's understanding of process numbers has gradually deviated from its actual \"coordinates\".</b></p><p><b>This is also the fundamental reason why Intel has established a new naming system.</b></p><p>As Tiger Sniff got the answer when interviewing engineers before: \"Intel is relatively more radical and demanding in formulating manufacturing process standards. But it is true that the manufacturing process has been delayed by 1 to 2 years. Saying that they are lagging behind does not mean that they have no possibility of catching up.\" But Intel's drastic process this time<b>rename</b>，<b>Maybe it's not that I don't believe myself, but that I smell the cruel reality that the market and capital have been confused by \"naming\" for a long time (such as the beginning), and even make business judgments based on it.</b></p><p>However, we thought of a question-even if a newly named product is launched, there is no reason for customers not to ask: \"How many nanometers is your intel7? How many nanometers is the benchmark of TSMC?\"</p><p>To be honest, we want to know how Intel answers this question when encountered.</p><p>Defend Moore's Law to the death?</p><p>At this extremely detailed \"process technology science popularization meeting\", Kissinger mentioned at least three times that \"Moore's Law will not die out, and Intel will continue to continue Moore's Law through various methods, such as changing materials, transistor structures, and packaging.\"</p><p>To be honest, apart from this meaningful new naming system,<b>Intel's most interesting and most noteworthy product is undoubtedly Intel20A after Intel3.</b></p><p>(Of course, Intel4 will also attract much attention as the first batch of processors to apply ASML's High-NA extreme ultraviolet radiation lithography (EUV) technology, but its symbolic significance is not as good as Intel20A.)</p><p>The reason why Intel 20A (5nm) is called the next watershed in the development of process technology in history by Intel is because it is the first chip to apply Intel's two \"pioneering technologies\":</p><p><ul><li><b>Gate-All-Around, a new transistor architecture to replace FinFET (Intel named it RibbonFET)</b></p><p></li><li><b>PowerVia, a power transmission system that can solve the \"interconnection bottleneck\".</b></p><p></li></ul>There is no need to elaborate on the importance of FinFET technology.</p><p>It is a 3D transistor technology (fin transistor) developed by Hu Zhengming, a professor of electrical engineering and computer science at the University of California, Berkeley, in 1999. The reason why Intel was able to take the lead in mass-producing 22nm transistors 12 years later was that TSMC and Samsung smoothly transitioned to the 16/14 nm process node, and FinFET contributed a lot.</p><p>It was this \"invention\" that enabled Moore's Law to \"extend its life\" for decades.</p><p>However, as the manufacturing process continues to shrink from 5nm to 3nm, semiconductor manufacturing experts have found that further reducing the size of FinFETs is increasingly limited by driving current and static control.</p><p>The Gate All Around that will replace it is commonly called GAAFET (Full Gate Field Effect Transistor), which uses a ribbon channel surrounded by the gate to achieve faster transistor switching speed and better control. Therefore, higher performance can be achieved in a smaller footprint. Samsung announced in 2020 that it would apply this architecture on 3nm process chips.</p><p><img src=\"https://static.tigerbbs.com/6a6fca1343877c136cbeef1a4caedada\" tg-width=\"1000\" tg-height=\"255\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image from Lam Semiconductor</p><p>Unlike FinFETs, in which higher currents require multiple side-by-side fins; The current carrying capacity of GAA transistors is mainly improved by stacking several nanosheets vertically (above), while the gate material is mainly wrapped around the channel. The size of the nanosheets can be scaled so that the transistors can be tuned to the specific performance required.</p><p>It sounds like the concept of \"nanosheets\" is actually not so difficult to understand; And in fact, this technology has been developed for many years. But the reason why it is not \"reused\" by the industry is,<b>The main bottleneck lies in \"materials\"</b>。</p><p>According to the explanation given by Fanlin Semiconductor, GAA transistors are made through the superlattice of \"alternating silicon\" and \"silicon-germanium epitaxial layer\", which is the basis of nanosheets. In addition, the manufacturing process is relatively complicated and may require ruthenium, Molybdenum, nickel and other new alloy materials are deposited, etched, and filled.</p><p>A semiconductor expert summed it up to Huxiu like this: \"It (GAA) will change the base material of the semiconductor, as will the materials connected to the semiconductor. At the same time, the physical structure of the entire transistor will also change.\" Therefore, Dr. Sanjay Natarajan, who led the team to develop this technology, called Intel's GAA-RibbonFET a \"major leap in transistor performance\", which is not false.</p><p>Based on the test chip results, they predict that the performance and density improvement brought by RibbonFET transistors will exceed that of current FinFET transistors. Intel 20A will be the first chip to apply RibbonFET.</p><p><img src=\"https://static.tigerbbs.com/e0a40c6ececaec4fa8741e6781f30b32\" tg-width=\"1000\" tg-height=\"487\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>The power transmission system PowerVia is a unique technology developed by Intel engineers. Dr. Sanjay Natarajan, as the development leader of this technology, pointed out that one of the biggest traditional problems in semiconductor transistor structures is \"low wiring efficiency\".</p><p>\"Traditional interconnection technology is interconnected at the top of the transistor layer, which often leads to intermixing of power lines and signal lines, resulting in low wiring efficiency, which in turn affects performance and power consumption.\"</p><p>Their solution is to place the power line under the transistor layer (that is, the back of the wafer). By reducing the power wiring on the front of the wafer, more \"open space\" is freed up to optimize signal wiring and reduce delay to achieve better power transmission.</p><p><img src=\"https://static.tigerbbs.com/711724a13d34832717d6e33d027d163f\" tg-width=\"1000\" tg-height=\"603\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>It is worth noting that although these two key technologies to be used in Intel20A are inevitably criticized as \"still in PPT state\" (after all, they are still PPT), Intel experts showed the scanning electron microscope images of these test chips, obviously after a series of tests.</p><p>As mentioned above, their successful application will determine whether Intel can overtake at the key node of 5nm.</p><p>From the time point of view, it is obvious that the \"realization of 7nm + + in 2023\" planned on the PPT in 2019 is not much apart from the \"realization of Intel20A in 2024\" planned this time. In other words, there is still a chance to make a comeback at the 5nm node.</p><p><img src=\"https://static.tigerbbs.com/9858abda999ad2b18407fdde87b7e61c\" tg-width=\"1000\" tg-height=\"561\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Intel's process product plan for October 2019</p><p>As Kissinger said, the advent of Intel Intel20A in 2024 and the real application of two key technologies will mark the beginning of the semiconductor \"Amy era\" (1 Amy = 0.1 nanometers).</p><p>Now, it's actually more like Intel shouting to the outside world: Do you think I still want to compete for leadership in the \"nano era\"? No, we're going into a unit smaller than nanometers to compete for the right to speak.</p><p><b>Written at the end... I hope it's not PPT</b></p><p>But then again, since the naming system in nanometers has been completely changed, and the next round of dramatic changes in transistor structures and materials are undergoing. In addition, Intel is also improving the bandwidth density and energy efficiency of chips from the packaging technology level...</p><p>Doesn't all this mean that the so-called digital unit of nanometers or ammeters has become increasingly meaningless?</p><p><b>Intel says it is defending Moore's Law, but in fact it has realized that it can no longer rely on Moore's Law.</b></p><p>Today, although the manufacturing process of Intel20A officially says that it has won this large order from Qualcomm, there are still many variables before 2024. Although we feel that Intel's press conference is of great significance, and the product planning makes people have no objection, PPT can be transformed into a real product, and it still needs the real thing to speak.</p><p>After all, the 14nm product, which was delayed for 4 years, was doing quite well in PPT at that time.</p>","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>Intel drops Amy bomb: TSMC's exaggerated propaganda is over</title>\n<style type=\"text/css\">\na,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,caption,center,cite,code,dd,del,details,dfn,div,dl,dt,\nem,embed,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,\nobject,ol,output,p,pre,q,ruby,s,samp,section,small,span,strike,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,tt,u,ul,var,video{ font:inherit;margin:0;padding:0;vertical-align:baseline;border:0 }\nbody{ font-size:16px; line-height:1.5; color:#999; background:transparent; }\n.wrapper{ overflow:hidden;word-break:break-all;padding:10px; }\nh1,h2{ font-weight:normal; line-height:1.35; margin-bottom:.6em; }\nh3,h4,h5,h6{ line-height:1.35; margin-bottom:1em; }\nh1{ font-size:24px; }\nh2{ font-size:20px; }\nh3{ font-size:18px; }\nh4{ font-size:16px; }\nh5{ font-size:14px; }\nh6{ font-size:12px; }\np,ul,ol,blockquote,dl,table{ margin:1.2em 0; }\nul,ol{ margin-left:2em; }\nul{ list-style:disc; }\nol{ list-style:decimal; }\nli,li p{ margin:10px 0;}\nimg{ max-width:100%;display:block;margin:0 auto 1em; }\nblockquote{ color:#B5B2B1; border-left:3px solid #aaa; padding:1em; }\nstrong,b{font-weight:bold;}\nem,i{font-style:italic;}\ntable{ width:100%;border-collapse:collapse;border-spacing:1px;margin:1em 0;font-size:.9em; }\nth,td{ padding:5px;text-align:left;border:1px solid #aaa; }\nth{ font-weight:bold;background:#5d5d5d; }\n.symbol-link{font-weight:bold;}\n/* header{ border-bottom:1px solid #494756; } */\n.title{ margin:0 0 8px;line-height:1.3;color:#ddd; }\n.meta {color:#5e5c6d;font-size:13px;margin:0 0 .5em; }\na{text-decoration:none; color:#2a4b87;}\n.meta .head { display: inline-block; overflow: hidden}\n.head .h-thumb { width: 30px; height: 30px; margin: 0; padding: 0; border-radius: 50%; float: left;}\n.head .h-content { margin: 0; padding: 0 0 0 9px; float: left;}\n.head .h-name {font-size: 13px; color: #eee; margin: 0;}\n.head .h-time {font-size: 12.5px; color: #7E829C; margin: 0;}\n.small {font-size: 12.5px; display: inline-block; transform: scale(0.9); -webkit-transform: scale(0.9); transform-origin: left; -webkit-transform-origin: left;}\n.smaller {font-size: 12.5px; display: inline-block; transform: scale(0.8); -webkit-transform: scale(0.8); transform-origin: left; -webkit-transform-origin: left;}\n.bt-text {font-size: 12px;margin: 1.5em 0 0 0}\n.bt-text p {margin: 0}\n</style>\n</head>\n<body>\n<div class=\"wrapper\">\n<header>\n<h2 class=\"title\">\nIntel drops Amy bomb: TSMC's exaggerated propaganda is over\n</h2>\n<h4 class=\"meta\">\n<a class=\"head\" href=\"https://laohu8.com/wemedia/101\">\n\n<div class=\"h-thumb\" style=\"background-image:url(https://static.tigerbbs.com/98669fe7974e42f3976b3db47528792d);background-size:cover;\"></div>\n\n<div class=\"h-content\">\n<p class=\"h-name\">虎嗅APP </p>\n<p class=\"h-time smaller\">2021-07-29 15:36</p>\n</div>\n</a>\n</h4>\n</header>\n<article>\n<p>Since Intel was confirmed by 100% conclusive evidence last year that it had delayed the 10nm process, lagged behind TSMC in the 7nm process, and lost its global process leadership position, public opinion has been concerned about the only company in the United States with full coverage from design, manufacturing to packaging and testing.

Although it attracted the attention of the industry with its generous and \"never giving up manufacturing\" attitude, it continued to be controversial because of its poor financial report;</p><p>Yesterday, four senior Intel manufacturing technology experts, including CEO Kissinger, once again disclosed Intel's process technology and implementation path on a large scale.<b>A \"new bomb\" was dropped on the semiconductor industry:</b></p><p><ul><li>Intel does have delays at 10nm and 7nm (if you are interested, you can read my article \"Intel Abdicates, TSMC Becomes King\"), but on the 5nm node, Intel believes that instead of delaying, it will complete the transcendence.</p><p></li></ul><ul><li>In order to deal with the \"false propaganda of manufacturing processes\" by rivals such as TSMC and correct everyone's misunderstanding of manufacturing processes, Intel directly abandoned the statement of \"10nm, 7nm, 5nm, 3nm\" that is essentially determined by Moore's Law, and directly adopted 100% Intel's new naming system from a subjective perspective-Intel7, Intel4, Intel3, Intel20A, Intel18A.</p><p></li></ul><ul><li>The Intel20A disclosed this time essentially corresponds to the 5nm process.<b>This is a manufacturing process node that Intel has kept silent about for the past two years, and the relevant time plan basically ended abruptly at 7nm.

Among them, this process will use a new transistor structure Gate-All-Around, which is not a FinFET structure that has made great contributions to the productization of processes below 22nm.</p><p></li></ul>In other words, this new structure chip using new materials will bring about major changes to the traditional process concept. Just like a semiconductor technology expert told Tiger Sniff: \"This new material structure and the manufacturing process are a few nanometers or so, it doesn't matter so much.\"</p><p><b>Intel's new process naming system: Wake up, customers</b></p><p>The naming of the manufacturing process has been criticized by the industry for a long time.</p><p>For example, we once mentioned in the article \"Intel Abdicates, TSMC Becomes King\" that many engineers in the industry believe that Intel has a more realistic attitude towards \"nano\" process numbers, and even said that \"Intel's 10nm chip benchmark is actually TSMC's 7nm, even better than the latter's 7nm.\"</p><p>This is why Kissinger has repeatedly called on everyone to correctly understand \"process numbers\" in public after taking office:</p><p>\"Including Intel, different process node naming and numbering schemes are used. These schemes neither refer to any specific measurement method nor fully demonstrate how to achieve the best balance of chip energy efficiency and performance.\" This is like those cars at auto shows that claim to have reached hundreds of thousands of Tops in their chips, and it is also like the \"Autonomous Driving Takeover Report\" released by California every year-without uniform test conditions and sufficient corporate integrity, it is absolutely unworthy of saying \"Who performs better than whom\" conclusion.</p><p>Therefore, Intel has made great efforts to change the naming system this time, saying: \"Let customers have a more accurate understanding of the evolution of process nodes in the entire industry, and then make more informed decisions.\"<b>In fact, the main purpose is to deal with the less reliable 5nm and 3nm process names of TSMC and Samsung.</b></p><p><ul><li>The Intel 7, which will be launched in the second half of 2021 (does it at least look like 7nm?), is actually the 10nm Enhanced SuperFin previously released by Intel;</p><p></li></ul><ul><li>The Intel 4 released in the first half of 2023 (at least it looks like 4nm?), is actually the 7nm of Intel's previous PPT;</p><p></li></ul><ul><li>The Intel3 released in the second half of 2023 is actually the 7nm + on Intel's previous PPT;</p><p></li></ul><ul><li><b>Intel20A released in the first half of 2024 (does it look like 2nm?), is actually 5nm under Intel standards;</b></p><p></li></ul><ul><li>Intel18A will be released in the first half of 2025, which is actually 5nm + under Intel standards.</p><p></li></ul><img src=\"https://static.tigerbbs.com/1ce380fc9b07caca9a43fa165a2e90a8\" tg-width=\"1000\" tg-height=\"471\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image via Intel</p><p>In fact, with the increasing complexity of transistor structures, as early as the beginning of the 21st century, the industry began to have a \"differentiation trend\" in the naming of nanometer processes of chips.</p><p>As we all know, microprocessors are made up of billions of transistors connected in a specific way. These transistors act as \"switches\" and are responsible for processing the ones and zeros of electronic data.</p><p>Kissinger explained that there is an area at the top of the transistor called the \"gate\", which determines whether the transistor is turned on or off. The \"process node\" refers to a complex scheme consisting of thousands of manufacturing steps required for transistors.</p><p>And almost all the top semiconductor companies have the same goal-to make these chips smaller, faster, cheaper, and more energy-efficient-the best example is Apple's 5nm process chip M1 (there are too many reviews about M1 You can see the review, I also bought an M1 Macbook Air, and I can't put it down).</p><p><img src=\"https://static.tigerbbs.com/ae99fc8b1663fb184dc959320da5b5a1\" tg-width=\"1000\" tg-height=\"384\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Initially, the name of the process process \"node\" corresponded to the gate length of the transistor and was measured in \"microns\".<b>As transistors became smaller and smaller, the length of gates became smaller and smaller, and the industry began to measure it in nanometers.</b></p><p>The key node about the change of process naming appeared in 1997.</p><p>\"With technological advances and the emergence of other innovative technologies such as strained silicon, faster, cheaper and more energy-efficient becomes equally important in addition to shrinking transistors.\" Kissinger believes that from this point on,<b>Traditional naming methods no longer match the actual transistor gate length.</b></p><p><b>In other words, transistor size is not the only determinant to some extent, and factors such as the \"interconnection\" between them cannot be ignored.</b></p><p>In 2011, after Intel launched FinFET transistor structure technology, the industry was further differentiated. It's an entirely new way to build transistors, with unique shapes and structures.</p><p>This structure is the key technology to continue to indent the stagnant 22nm.<b>But it must be clear that starting from 22nm, not to mention the public, even the industry's understanding of process numbers has gradually deviated from its actual \"coordinates\".</b></p><p><b>This is also the fundamental reason why Intel has established a new naming system.</b></p><p>As Tiger Sniff got the answer when interviewing engineers before: \"Intel is relatively more radical and demanding in formulating manufacturing process standards. But it is true that the manufacturing process has been delayed by 1 to 2 years. Saying that they are lagging behind does not mean that they have no possibility of catching up.\" But Intel's drastic process this time<b>rename</b>，<b>Maybe it's not that I don't believe myself, but that I smell the cruel reality that the market and capital have been confused by \"naming\" for a long time (such as the beginning), and even make business judgments based on it.</b></p><p>However, we thought of a question-even if a newly named product is launched, there is no reason for customers not to ask: \"How many nanometers is your intel7? How many nanometers is the benchmark of TSMC?\"</p><p>To be honest, we want to know how Intel answers this question when encountered.</p><p>Defend Moore's Law to the death?</p><p>At this extremely detailed \"process technology science popularization meeting\", Kissinger mentioned at least three times that \"Moore's Law will not die out, and Intel will continue to continue Moore's Law through various methods, such as changing materials, transistor structures, and packaging.\"</p><p>To be honest, apart from this meaningful new naming system,<b>Intel's most interesting and most noteworthy product is undoubtedly Intel20A after Intel3.</b></p><p>(Of course, Intel4 will also attract much attention as the first batch of processors to apply ASML's High-NA extreme ultraviolet radiation lithography (EUV) technology, but its symbolic significance is not as good as Intel20A.)</p><p>The reason why Intel 20A (5nm) is called the next watershed in the development of process technology in history by Intel is because it is the first chip to apply Intel's two \"pioneering technologies\":</p><p><ul><li><b>Gate-All-Around, a new transistor architecture to replace FinFET (Intel named it RibbonFET)</b></p><p></li><li><b>PowerVia, a power transmission system that can solve the \"interconnection bottleneck\".</b></p><p></li></ul>There is no need to elaborate on the importance of FinFET technology.</p><p>It is a 3D transistor technology (fin transistor) developed by Hu Zhengming, a professor of electrical engineering and computer science at the University of California, Berkeley, in 1999. The reason why Intel was able to take the lead in mass-producing 22nm transistors 12 years later was that TSMC and Samsung smoothly transitioned to the 16/14 nm process node, and FinFET contributed a lot.</p><p>It was this \"invention\" that enabled Moore's Law to \"extend its life\" for decades.</p><p>However, as the manufacturing process continues to shrink from 5nm to 3nm, semiconductor manufacturing experts have found that further reducing the size of FinFETs is increasingly limited by driving current and static control.</p><p>The Gate All Around that will replace it is commonly called GAAFET (Full Gate Field Effect Transistor), which uses a ribbon channel surrounded by the gate to achieve faster transistor switching speed and better control. Therefore, higher performance can be achieved in a smaller footprint. Samsung announced in 2020 that it would apply this architecture on 3nm process chips.</p><p><img src=\"https://static.tigerbbs.com/6a6fca1343877c136cbeef1a4caedada\" tg-width=\"1000\" tg-height=\"255\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image from Lam Semiconductor</p><p>Unlike FinFETs, in which higher currents require multiple side-by-side fins; The current carrying capacity of GAA transistors is mainly improved by stacking several nanosheets vertically (above), while the gate material is mainly wrapped around the channel. The size of the nanosheets can be scaled so that the transistors can be tuned to the specific performance required.</p><p>It sounds like the concept of \"nanosheets\" is actually not so difficult to understand; And in fact, this technology has been developed for many years. But the reason why it is not \"reused\" by the industry is,<b>The main bottleneck lies in \"materials\"</b>。</p><p>According to the explanation given by Fanlin Semiconductor, GAA transistors are made through the superlattice of \"alternating silicon\" and \"silicon-germanium epitaxial layer\", which is the basis of nanosheets. In addition, the manufacturing process is relatively complicated and may require ruthenium, Molybdenum, nickel and other new alloy materials are deposited, etched, and filled.</p><p>A semiconductor expert summed it up to Huxiu like this: \"It (GAA) will change the base material of the semiconductor, as will the materials connected to the semiconductor. At the same time, the physical structure of the entire transistor will also change.\" Therefore, Dr. Sanjay Natarajan, who led the team to develop this technology, called Intel's GAA-RibbonFET a \"major leap in transistor performance\", which is not false.</p><p>Based on the test chip results, they predict that the performance and density improvement brought by RibbonFET transistors will exceed that of current FinFET transistors. Intel 20A will be the first chip to apply RibbonFET.</p><p><img src=\"https://static.tigerbbs.com/e0a40c6ececaec4fa8741e6781f30b32\" tg-width=\"1000\" tg-height=\"487\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>The power transmission system PowerVia is a unique technology developed by Intel engineers.

By reducing the power wiring on the front of the wafer, more \"open space\" is freed up to optimize signal wiring and reduce delay to achieve better power transmission.</p><p><img src=\"https://static.tigerbbs.com/711724a13d34832717d6e33d027d163f\" tg-width=\"1000\" tg-height=\"603\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>It is worth noting that although these two key technologies to be used in Intel20A are inevitably criticized as \"still in PPT state\" (after all, they are still PPT), Intel experts showed the scanning electron microscope images of these test chips, obviously after a series of tests.</p><p>As mentioned above, their successful application will determine whether Intel can overtake at the key node of 5nm.</p><p>From the time point of view, it is obvious that the \"realization of 7nm + + in 2023\" planned on the PPT in 2019 is not much apart from the \"realization of Intel20A in 2024\" planned this time.

IC Insights发布的《2021年Q1全球Top15半导体公司业绩与排名》指出，英特尔虽然位列第一，但却是所有厂商中唯一一家营收下滑的企业。\n\n图片来自IC Insights\n英特尔当然焦虑。这种焦虑可能体现在：\n\n受到资本市场巨大压力，2021年年初突然换帅，重新启用有40年制造技术履历的帕特·基辛格(Pat Gelsinger)为新任CEO。\n\n\n迅速接受了阿斯麦比自己更为先进的EUV制造工艺，用了大约两个季度的时间修复了7nm技术。\n\n\n在制造环节投入巨资。今年3月，帕特·基辛格正式公布十分关键的“IDM 2.0”战略，宣布重返晶圆代工市场，同时宣布投资200亿美元在美国亚利桑那州新建两座晶圆厂；5月再次宣布，投资35亿美元升级新墨西哥州工厂，投资100亿美元在以色列兴建的芯片厂，还计划在欧盟建厂。\n\n\n越来越多的英特尔半导体技术专家现身说法，为自己的制造技术正名，强调“每家晶圆厂的制程数据有对外宣传的差异”。\n\n当然，根据虎嗅平台的观察和媒体反应，在国内大大小小的人工智能、物联网以及数据中心市场活动上，你能越来越多次看到英特尔出现的身影。\n\n英特尔 CEO 帕特·基辛格\n以重新夺回“制程节点”为目标的英特尔，今年3月发布的“IDM2.0战略”就以大手笔和”绝不放弃制造”的态度虽然引起产业重视，但因为表现不佳的财报状况持续受到争议；\n而昨天，包括CEO基辛格在内的4位英特尔高级制造技术专家，再次通过大范围公开英特尔的制程技术和实现路径，向半导体产业投掷了一枚“新炸弹”：\n\n英特尔的确在10nm和7nm有所延迟（如果感兴趣，可以看我的这篇文章《英特尔退位，台积电称王》），但在5nm节点上，英特尔自认为非但没有延迟，反而会完成超越。\n\n\n为了应对台积电等对手的“制程虚假宣传”，以及纠正大家对制程的认知误区，英特尔直接舍弃了“10nm，7nm，5nm，3nm”这一本质上由摩尔定律决定的说法，而是直接采用100%英特尔主观视角的新命名体系——Intel7，Intel4，Intel3，Intel20A，Intel18A。\n\n\n这一次公开的Intel20A，本质对应的就是5nm制程。这是一个英特尔近2年来闭口不谈的制程节点，相关时间计划基本到7nm就戛然截止了。英特尔首次宣布将通过Intel20A，进入“埃米时代”。\n\n\nIntel20A背后两大关键技术非常值得注意。其中，这个制程将会采用全新的晶体管结构Gate-All-Around，并非是为22nm以下制程产品化立下汗马功劳的FinFET结构。\n\n换言之，这种应用了新材料的新结构芯片，将会对传统制程概念，产生重大改变。就如一位半导体技术专家告诉虎嗅：“这种新的材料结构，制程这些几纳米啥的就没那么大的关系了。”\n英特尔新制程命名体系：快醒醒，客户们\n关于制程的命名问题，被产业诟病已久。\n譬如我们曾在《英特尔退位，台积电称王》这篇文章里提及，业内不少工程师认为，英特尔在对待“纳米”制程数字的态度更实在，甚至表示“英特尔的10nm芯片对标的其实是台积电的7nm，甚至比后者的7nm都好”。\n这也是基辛格上任后，多次在公开场合呼吁大家正确理解“制程数字”：\n\n “包括英特尔在内，使用着各不相同的制程节点命名和编号方案，这些方案既不指代任何具体的度量方法，也无法全面展现如何实现芯片能效和性能的最佳平衡。”\n\n这就像是车展上那些号称自己芯片达到几百几千Tops的汽车，也像是加州每年发布的《自动驾驶接管报告》——没有统一测试条件和足够的企业诚信度，就绝对不配说出“谁比谁性能好”的结论。\n所以，英特尔这次兴师动众地更换了命名体系，美名曰：“让客户对整个行业的制程节点演进有一个更准确认知，进而做出更明智的决策”，其实主要目的就是对付台积电和三星不那么太靠谱的5nm和3nm制程名字。\n\n2021年下半年将推出的Intel 7 （是不是至少看起来像是7nm？），其实就是英特尔之前发布的10nm Enhanced SuperFin；\n\n\n2023年上半年发布的Intel 4（至少看起来像4nm？），其实就是英特尔之前PPT的7nm；\n\n\n2023年下半年发布的Intel3，其实就是英特尔之前PPT上的7nm+；\n\n\n2024年上半年发布的Intel20A（看起来像不像2nm？），其实就是英特尔标准下的5nm；\n\n\n2025年上半年发布Intel18A，其实就是英特尔标准下的5nm+。\n\n\n图片来自英特尔\n实际上，随着晶体管结构的愈加复杂，早在21世纪初，产业内就开始对芯片的纳米制程命名有了“分化趋势”。\n我们都清楚，微处理器是由以特定方式连接起来的数十亿晶体管组成。这些晶体管充当了“开关”的角色，负责处理电子数据的1和0。\n基辛格解释，在晶体管顶部有一个区域叫“栅极”，它决定了晶体管是开启还是关闭。而“制程节点”指代的是晶体管所需的数千个制造步骤组成的复杂方案。\n而所有最顶级半导体公司几乎都有同一个目标——让这些芯片变得更小、更快、更便宜、更高能效——最好的例子莫过于苹果的5nm制程芯片M1（有太多关于M1的测评可以去看，我也买了一台M1的Macbook Air，爱不释手）。\n\n最初，制程工艺“节点”的名称与晶体管的栅极长度相对应，并以“微米”为度量单位。随着晶体管越变越小，栅极的长度越来越微缩，产业开始以纳米为度量单位。\n而关于制程命名改变的关键节点出现在1997年。\n“随着技术进步和应变硅（strained silicon）等其他创新技术的出现，除了缩小晶体管，更快、更便宜和更高能效也变得同样重要。” 基辛格认为，从这时开始，传统命名方法不再与实际的晶体管栅极长度相匹配。\n换言之，晶体管尺寸在某种程度上不是唯一的决定因素，它们之间的“互连”等因素也不能忽略。\n2011年，在英特尔推出FinFET晶体管结构技术后，行业进一步分化。这是一种构建晶体管的全新方式，具有独特的形状和结构。\n这个结构就是将停滞不前的22nm继续往下缩进的关键技术。但要很显然，从22nm开始，不要说大众，就连产业内对制程数字的理解与它的实际“坐标”也开始逐渐脱离。\n这也是英特尔如今建立新命名体系的根本缘由。\n\n 正如虎嗅之前在采访工程师时得到的答案：“英特尔在制造工艺标准制定上相对更激进，要求也更高。但的确制程延迟了1~2年，说落后并不意味着他们没有追赶的可能性。”\n\n但英特尔这次大刀阔斧的制程更名，也许不是不相信自己，而是嗅到了市场和资本已经被“命名”困惑已久（譬如开头），甚至依此来做出商务判断的残酷现实。\n不过我们想到了一个问题——即便推出了新命名产品，客户没有理由不问一句：“你这intel7到底几纳米？对标的是台积电的几纳米？”\n说实话，我们更想知道英特尔在遇到这个问题时怎么回答。\n誓死捍卫摩尔定律？\n基辛格在这次可谓是极为详尽的“制程技术科普会”上，至少提了三次关于“摩尔定律不会消亡，英特尔会通过各种方法，如改材料、晶体管结构，以及封装等角度，继续来延续摩尔定律”的决心。\n实话讲，除了这个意味深长的新命名体系，英特尔最有趣且最应该受到关注的产品，毫无疑问是Intel3之后的Intel20A。\n（当然，Intel4 将作为第一批应用阿斯麦高数值孔径（High-NA）极紫外辐射光刻技术(EUV)的处理器也倍受瞩目，但象征意义不如Intel20A。）\nIntel 20A（5nm）之所以被英特尔称为历史上制程技术发展的下一个分水岭，是因为它是第一块应用英特尔两大“开创性技术”的芯片：\n\n替代FinFET的全新晶体管架构 Gate-All-Around（英特尔把它命名为RibbonFET）\n能够解决“互联瓶颈”的电能传输系统PowerVia。\n\nFinFET技术的重要性已经无须赘述。\n它是加州伯克利大学电子工程与计算机专业教授胡正明在1999年研发出的 3D 晶体管技术（鳍型晶体管）。英特尔之所以能在 12 年后率先量产出 22nm 晶体管，台积电与三星顺利过渡至 16/14nm 制程节点，FinFET功不可没。\n正是这项“发明”，摩尔定律才得以“延寿”数十年。\n但是，随着制程从5nm持续缩进至3nm，半导体制造专家们发现，进一步减少 FinFET 尺寸，就越来越受到驱动电流和静电控制的限制。\n而将要替代它的Gate All Around的常用名为GAAFET（全栅场效应管），它使用栅极包围的带状通道，从而能实现更快的晶体管切换速度和更好的控制。因此，在更小的占用空间内，可具备更高的性能。三星在2020年曾宣布将在3nm制程芯片上应用这一架构。\n\n图片来自泛林半导体\n与 FinFET不同的是，在 FinFET 中，较高电流需要多个并排的鳍片；GAA 晶体管的载流能力主要是通过垂直堆叠几个纳米片（上图），而栅极材料主要是包裹在沟道周围来提高的。纳米片的尺寸可以按比例缩放，以便晶体管可以按照要求的特定性能进行调整。\n听起来，“纳米片”的概念其实理解起来并不是那么困难；而且实际上，这项技术已经被研发多年。但其之所以不受业内“重用”，主要瓶颈就在于“材料”。\n根据泛林半导体给出的解释，GAA晶体管是通过“交替硅”和“硅锗外延层”的超晶格来制作的，这是构成纳米片的基础，此外制作工艺相对复杂，可能需要钌、钼、镍等各种合金新材料进行沉积、蚀刻、填充。\n\n 一位半导体专家这样给虎嗅总结：“它（GAA）将对半导体的基底材料进行更改，半导体连接的材料也要进行更改。同时整个晶体管的物理结构也要变化。”\n\n因此，带领团队开发这项技术的Sanjay Natarajan博士将英特尔的GAA——RibbonFET称为一次“晶体管性能上的重大飞跃”，并非虚话。\n根据测试芯片结果，他们预计RibbonFET晶体管带来的性能和密度提升，将超过当下的FinFET晶体管。而Intel 20A将是应用RibbonFET的第一枚芯片。\n\n而电能传输系统PowerVia则是英特尔工程师开发的一项独特技术。Sanjay Natarajan博士作为这项技术的开发负责人，指出半导体晶体管结构中存在的最大传统问题之一便是“布线效率低下”。\n“传统互连技术是在晶体管层的顶部进行互联，经常产生电源线和信号线的互混，导致了布线效率低下，进而影响性能和功耗。”\n他们的解决方法，便是把电源线置于晶体管层的下面（也就是晶圆的背面）。通过减少晶圆正面的电源布线，腾出更多的“空地儿”用于优化信号布线，并减少时延，实现更好的电能传输。\n\n值得注意的是，这两项将用于Intel20A的关键技术，虽然不可避免被人诟病为“仍然处于PPT状态”（毕竟还都是PPT），但英特尔的专家们展示了这些测试芯片的扫描电镜图像，显然经过了一系列测试。\n就像上面所说，它们的成功应用，将决定着英特尔是否能在5nm这个关键节点上进行反超。\n从时间来看，很明显，2019年时PPT上规划的“2023年实现7nm++”，与这次规划的“2024年实现Intel20A”没有多少间隔。也就是说，依然有机会在5nm这个节点上翻盘。\n\n英特尔2019年10月的制程产品规划图\n如基辛格所说，英特尔Intel20A在2024年的问世与两大关键技术的真正应用，将标志着半导体“埃米时代”（1埃米=0.1纳米）的启幕。\n现在来听，其实更像是英特尔在向外界喊话：你们以为我还想在“纳米时代”争夺领导权？不，我们要进入一个比纳米更小的单位去争夺话语权了。\n写在最后…希望不是PPT\n但话说回来，既然完全改变了以纳米为单位的命名体系，而且晶体管结构和材料正在发生下一轮巨大变化。此外，英特尔也在从封装技术层面提高芯片的带宽密度和能效……\n这一切难道不是意味着，所谓的纳米还是埃米的数字单位，已经越来越没意义了吗？\n英特尔嘴上说在捍卫摩尔定律，其实已经认识到不能再依靠摩尔定律。\n如今，Intel20A的制造工艺虽然官方说拿下了高通这个大订单，但距离2024年变数还有很大。我们虽然觉得英特尔这场发布会的意义重大，并且产品规划让人没有异议，但是PPT能够转变称真正的产品，还是需要实物说话。\n毕竟，当年延迟了4年的14nm产品，当时PPT做的也挺不错的。","news_type":1,"symbols_score_info":{"TSM":0.9,"EWT":0.9,"03145":0.9,"INTC":0.9,"03086":0.9,"09086":0.9,"TWmain":0.9}},"isVote":1,"tweetType":1,"viewCount":2275,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":808087297,"gmtCreate":1627544729719,"gmtModify":1703492037799,"author":{"id":"3586587763605977","authorId":"3586587763605977","name":"程導绅","avatar":"https://static.tigerbbs.com/17e557db7a706e6821394c3f5dc700d2","crmLevel":1,"crmLevelSwitch":0,"followedFlag":false,"idStr":"3586587763605977","authorIdStr":"3586587763605977"},"themes":[],"htmlText":"Hi","listText":"Hi","text":"Hi","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":0,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/808087297","repostId":"2155908504","repostType":4,"repost":{"id":"2155908504","kind":"news","pubTimestamp":1627544101,"share":"https://ttm.financial/m/news/2155908504?lang=en_US&edition=fundamental","pubTime":"2021-07-29

It is still far from the threshold of \"substantial further progress\" (\"substantial further progress\") but closer; ② Downplayed the market's concerns that the Delta variant virus will drag down the economic outlook; ③ Reiterate that inflation is temporary and there is no need to panic; ④ The high probability of reducing QE in the future will be that Treasury Bond and MBS will be reduced together; ⑤ Emphasize again that it is too early to talk about rate hike; ⑥ Set up a standing repurchase facility (SRF), which is divided into domestic primary dealers and overseas central banks in the United States.</p><p>The most important signal of this meeting is undoubtedly that the Federal Reserve has begun to warm up for cutting QE purchases (Taper). Policy communication is an art. If it is too abrupt and blunt, market expectations will often overshoot, causing violent fluctuations in asset prices, similar to the \"cutting panic\" in May 2013. Therefore, in this policy cycle, the Fed's policy exit and communication mode is gradual, smooth and transparent.</p><p>In the wording of this meeting statement, the most important change is that \"some progress has been made in economic goals and will continue to be evaluated at future meetings\". The Delta mutant virus that the market is worried about has not shaken the Federal Reserve's overall optimistic expectations for the economic outlook. Powell believes that the impact of the epidemic on the economy \"may be weaker by wave.\"</p><p>Considering that Taper's threshold is \"further significant progress\" in the economy, we recommend focusing on how well the employment gap is filled. The employment gap caused by this round of epidemic was still 6.76 million unfilled as of June, with a recovery rate of 70%. When the Federal Reserve announced Taper in December 2013, the recovery rate of the employment gap caused by the financial crisis was 88%. If the average in the second half of the year About 690,000 new jobs are created every month, and it is not difficult to achieve a similar gap recovery rate by the end of the year and December.</p><p>The market is always concerned about the rhythm of Taper, and at present, expectations are gradually becoming consistent. It is not surprising that the Fed is on hold at this meeting. The market generally expects that the annual central bank meeting at Jackson Hole in August or the FOMC meeting in September will be the time when the Fed begins to hint at the consideration of Taper, and may officially announce Taper at the end of 2021 or early 2022. We maintain our previous judgment that it was announced at the December FOMC meeting and will be implemented in 2022.</p><p>According to Powell, the July FOMC meeting is the first in-depth internal discussion by Fed officials on the possible timing and varieties involved in Taper in the future. Although there is no internal consensus on when to start Taper, it is inclined to cut U.S. Treasury Bond and MBS at the same time once Taper.</p><p>Looking back at the last round of Taper, in 2014, the Federal Reserve reduced its monthly purchase quota (US Treasury Bond + MBS) by US $10 billion at each meeting, and officially stopped QE at the October meeting, which took 10 months to complete. Compared with the current situation, the Federal Reserve's monthly purchase quota (US Treasury Bond + MBS) is US $120 billion. If the monthly quota is reduced by US $15 billion, it will take about 8 months to stop QE. If Taper is announced in December, it will roughly end in 2022Q3.</p><p><img src=\"https://static.tigerbbs.com/6292deabf5669e43200af797b2a273c6\" tg-width=\"550\" tg-height=\"417\" referrerpolicy=\"no-referrer\"></p><p>In terms of inflation, this meeting reconfirmed that the Fed has basically given up its forecast of when inflation will peak, but its bottom line is to keep long-term inflation expectations out of control. This is why inflation data continues to exceed expectations, but the Fed still firmly believes that \"inflation is temporary\" reasons. Powell also emphasized that \"if short-term price increases do not affect long-term inflation expectations, then it probably will not affect future inflation paths.\"</p><p>The Fed's most concerned measure of inflation expectations-the Common Inflation Expectations Index (CIE), which combines professional forecasters, household surveys and market-implied measures of inflation expectations. Professional forecasters and businesses tend to predict inflation more accurately than household surveys or market pricing.

The reason why it once fell below 1.2% is mainly due to technical factors at the transaction level (short covering, pension stocks and bonds Rebalancing, strong overseas demand, etc.).</p><p>When the 10-year US Treasury yields fell below 1.20%, what we need to think about is whether US Treasury yields's current pricing of the U.S. economic outlook is too pessimistic, especially considering that the previous level of 1.20% from the end of January to the beginning of February corresponds to the background of U.S. fiscal stimulus and large-scale vaccination have not yet landed.</p><p><img src=\"https://static.tigerbbs.com/d6a7a8ca1c0e4573b2e48caa2fd25614\" tg-width=\"550\" tg-height=\"428\" referrerpolicy=\"no-referrer\"></p><p>Considering that the current US Treasury yields's pricing of the economic outlook is too pessimistic, the driving force of technical factors is unsustainable, and the law that the rebound space of the U.S. bond bear market is about 50bp, the downside space of the US Treasury yields in the second half of the decade is limited.</p><p>Looking back at 2013-2014, the slowdown in employment recovery in Q3 2013 caused the Federal Reserve to stand still at the September-October interest rate meeting. The 10-year US Treasury yields rose by 38bp from a low of 2.51% at 10.23 to 2.89% before the December interest rate meeting. The Federal Reserve officially announced it on December 18 and implemented it in early 2014. The 10-year US Treasury yields rose again by 15bp to peak at the year's high of 3.04%, and then returned to the downward channel in 2014 (global economic concerns).</p><p>Referring to historical experience, we believe that as the Federal Reserve begins to release Taper signals in the third quarter, the 10-year US Treasury yields may rise again and gradually peak after the official announcement of Taper, but it is difficult to break through the previous high of 1.70-1.80%.</p><p>Therefore, even if the US Treasury yields returns to the upward channel in the future, the slope is difficult to be too steep, and there is a high probability that it will be in a wide range of fluctuations. In addition, the market has very full expectations for the Fed to withdraw from easing, so it will not happen again in February-March at the beginning of the year. The situation that the upward trend of US Treasury yields has caused a serious impact on the equity market.

further progress”）的门槛仍有距离但也更近了；②淡化了市场对Delta变异病毒拖累经济前景的担忧；③重申通胀是暂时的，无需感到恐慌；④未来削减QE大概率会是国债和MBS一起减；⑤再次强调谈论加息过早；⑥设立常备回购便利工具（SRF），分为面向美国国内一级交易商和海外央行。\n本次会议最重要的信号，无疑就是美联储开始为削减QE购买（Taper）进行预热。政策沟通是门艺术，过于突兀与生硬，市场预期往往就会超调，引发资产价格剧烈波动，类似2013年5月的“削减恐慌”。所以，在本轮政策周期中，美联储政策退出和沟通的模式都是力求渐进、平滑和透明。\n本次会议声明措辞中，最重要的变化就是“经济目标已经取得一些进展并将在未来的会议上继续评估”。市场担忧的Delta变异病毒，并没有动摇美联储对经济前景整体乐观的预期，鲍威尔认为疫情对经济的冲击“可能一波比一波弱”。\n考虑到Taper的门槛是经济取得“进一步重大进展”，我们建议关注就业缺口的填补程度。本轮疫情造成的就业缺口截止6月仍差676万人未填补，恢复率为70%，而2013年12月美联储宣布Taper时，金融危机造成的就业缺口恢复率为88%，若下半年平均每月新增就业约69万人，年底12月实现类似的缺口恢复率难度不大。\n市场关心的始终是Taper的节奏，目前来看预期也逐渐走向一致。本次会议美联储按兵不动并不意外，市场普遍预期是8月Jackson Hole的央行年会或者9月FOMC会议将会是美联储开始暗示考虑Taper的时点，并且可能在2021年底或2022年初正式宣布Taper。我们则维持此前的判断，即12月FOMC会议宣布并在2022年开始执行。\n根据鲍威尔所言，7月FOMC会议是美联储官员首次针对未来Taper可能的时点和涉及品种进行深度内部讨论，虽然内部尚未对何时开始Taper形成共识，但倾向于一旦Taper就同时削减美国国债和MBS。\n回顾上一轮Taper，2014年美联储在每次会议上将每月购买额度（美国国债+MBS）减少100亿美元，并在10月会议上正式停止QE，历时10个月完成。对比当下，美联储每月购买额度（美国国债+MBS）为1200亿美元，若按照每月减少额度150亿美元，则大致需要8个月实现停止QE，如果12月宣布Taper，那么大致2022Q3结束。\n\n通胀方面，本次会议再次确认了美联储基本放弃对通胀何时见顶的预测，但它的底线是守住长期通胀预期不能失控，这也是为何通胀数据连续超预期，美联储却依然坚信“通胀是暂时性”的原因。鲍威尔也强调“如果短期的物价水平上涨不会影响长期的通胀预期，那么它就很可能不会影响未来的通胀路径”。\n美联储最关注的通胀预期指标——共同通胀预期指数（CIE），该指数综合了专业预测者、家庭调查和市场隐含的通胀预期指标，而专业预测者和企业对通胀的预测往往比家庭调查或市场定价更准确。CIE从2020Q3的1.94%上行到2021Q2的2.05%，目前并没有跟随通胀数据而飙升。\n\n过去一个月美债利率之所以下行，主要来自于变异病毒肆虐叠加财政刺激僵局所引发的经济担忧，而之所以一度跌破1.2%，主要来自交易层面的技术因素（空头回补、养老金股债再平衡、海外需求较强等）。\n在10年美债利率跌破1.20%之际，我们需要思考的是当前美债利率对美国经济前景的定价是否过于悲观，尤其是考虑到此前1月底-2月初1.20%的水平对应的背景是美国财政刺激和疫苗大规模接种都还没有落地。\n\n考虑到当前美债利率对经济前景的定价过于悲观、技术性因素的驱动力量难以持续、以及美债熊市反弹空间约50bp的规律，下半年10年美债利率下行空间有限。\n回顾2013-2014年，2013Q3就业复苏放缓导致美联储在9-10月议息会议上按兵不动，10年美债利率从10.23低点2.51%累计上行38bp至12月议息会议前的2.89%。美联储在12.18正式官宣并在2014年初执行，10年美债利率再次上行15bp至年内高点3.04%见顶，随后在2014年重回下降通道（全球经济担忧）。\n参考历史经验，我们认为，随着美联储在三季度开始释放Taper信号，10年美债利率可能会再次上行，并在Taper官宣落地后逐步见顶，但很难突破前期高点1.70-1.80%。\n所以，接下来即使美债利率重回上行通道，但是斜率很难太陡，大概率处于宽幅区间震荡格局，再加上市场对联储退出宽松预期非常充分，所以不会再出现年初2-3月份那种因为美债利率上行对权益市场造成严重冲击的情况。（完）","news_type":1,"symbols_score_info":{"161125":0.9,"513500":0.9,"OEX":0.9,"DOG":0.9,"SDS":0.9,"IEI":0.9,"BND":0.9,"TLT":0.9,"TQQQ":0.9,"DJX":0.9,".IXIC":0.9,"SHY":0.9,"SSO":0.9,"TNmain":0.9,"UPRO":0.9,".DJI":0.9,"SPXU":0.9,"IEF":0.9,"GOVT":0.9,"ESmain":0.9,"QLD":0.9,"IVV":0.9,"QQQ":0.9,"DXD":0.9,"SDOW":0.9,"DDM":0.9,"SPY":0.9,"ZFmain":0.9,"NQmain":0.9,"QID":0.9,"SH":0.9,"MNQmain":0.9,"SQQQ":0.9,"UDOW":0.9,"UBmain":0.9,"ZTmain":0.9,"ZNmain":0.9,".SPX":0.9,"PSQ":0.9,"OEF":0.9,"ZBmain":0.9}},"isVote":1,"tweetType":1,"viewCount":1429,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":127346059,"gmtCreate":1624837541771,"gmtModify":1703845682609,"author":{"id":"3586587763605977","authorId":"3586587763605977","name":"程導绅","avatar":"https://static.tigerbbs.com/17e557db7a706e6821394c3f5dc700d2","crmLevel":1,"crmLevelSwitch":0,"followedFlag":false,"idStr":"3586587763605977","authorIdStr":"3586587763605977"},"themes":[],"htmlText":"??","listText":"??","text":"??","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":0,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/127346059","repostId":"2146121007","repostType":4,"isVote":1,"tweetType":1,"viewCount":1657,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":124650528,"gmtCreate":1624763473364,"gmtModify":1703844687981,"author":{"id":"3586587763605977","authorId":"3586587763605977","name":"程導绅","avatar":"https://static.tigerbbs.com/17e557db7a706e6821394c3f5dc700d2","crmLevel":1,"crmLevelSwitch":0,"followedFlag":false,"idStr":"3586587763605977","authorIdStr":"3586587763605977"},"themes":[],"htmlText":"??","listText":"??","text":"??","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":2,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/124650528","repostId":"1165215748","repostType":4,"repost":{"id":"1165215748","kind":"news","pubTimestamp":1624762603,"share":"https://ttm.financial/m/news/1165215748?lang=en_US&edition=fundamental","pubTime":"2021-06-27

Just like a semiconductor technology expert told Tiger Sniff: \"This new material structure and the manufacturing process are a few nanometers or so, it doesn't matter so much.\"</p><p><b>Intel's new process naming system: Wake up, customers</b></p><p>The naming of the manufacturing process has been criticized by the industry for a long time.</p><p>For example, we once mentioned in the article \"Intel Abdicates, TSMC Becomes King\" that many engineers in the industry believe that Intel has a more realistic attitude towards \"nano\" process numbers, and even said that \"Intel's 10nm chip benchmark is actually TSMC's 7nm, even better than the latter's 7nm.\"</p><p>This is why Kissinger has repeatedly called on everyone to correctly understand \"process numbers\" in public after taking office:</p><p>\"Including Intel, different process node naming and numbering schemes are used. These schemes neither refer to any specific measurement method nor fully demonstrate how to achieve the best balance of chip energy efficiency and performance.\" This is like those cars at auto shows that claim to have reached hundreds of thousands of Tops in their chips, and it is also like the \"Autonomous Driving Takeover Report\" released by California every year-without uniform test conditions and sufficient corporate integrity, it is absolutely unworthy of saying \"Who performs better than whom\" conclusion.</p><p>Therefore, Intel has made great efforts to change the naming system this time, saying: \"Let customers have a more accurate understanding of the evolution of process nodes in the entire industry, and then make more informed decisions.\"<b>In fact, the main purpose is to deal with the less reliable 5nm and 3nm process names of TSMC and Samsung.</b></p><p><ul><li>The Intel 7, which will be launched in the second half of 2021 (does it at least look like 7nm?), is actually the 10nm Enhanced SuperFin previously released by Intel;</p><p></li></ul><ul><li>The Intel 4 released in the first half of 2023 (at least it looks like 4nm?), is actually the 7nm of Intel's previous PPT;</p><p></li></ul><ul><li>The Intel3 released in the second half of 2023 is actually the 7nm + on Intel's previous PPT;</p><p></li></ul><ul><li><b>Intel20A released in the first half of 2024 (does it look like 2nm?), is actually 5nm under Intel standards;</b></p><p></li></ul><ul><li>Intel18A will be released in the first half of 2025, which is actually 5nm + under Intel standards.</p><p></li></ul><img src=\"https://static.tigerbbs.com/1ce380fc9b07caca9a43fa165a2e90a8\" tg-width=\"1000\" tg-height=\"471\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image via Intel</p><p>In fact, with the increasing complexity of transistor structures, as early as the beginning of the 21st century, the industry began to have a \"differentiation trend\" in the naming of nanometer processes of chips.</p><p>As we all know, microprocessors are made up of billions of transistors connected in a specific way. These transistors act as \"switches\" and are responsible for processing the ones and zeros of electronic data.</p><p>Kissinger explained that there is an area at the top of the transistor called the \"gate\", which determines whether the transistor is turned on or off. The \"process node\" refers to a complex scheme consisting of thousands of manufacturing steps required for transistors.</p><p>And almost all the top semiconductor companies have the same goal-to make these chips smaller, faster, cheaper, and more energy-efficient-the best example is Apple's 5nm process chip M1 (there are too many reviews about M1 You can see the review, I also bought an M1 Macbook Air, and I can't put it down).</p><p><img src=\"https://static.tigerbbs.com/ae99fc8b1663fb184dc959320da5b5a1\" tg-width=\"1000\" tg-height=\"384\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Initially, the name of the process process \"node\" corresponded to the gate length of the transistor and was measured in \"microns\".<b>As transistors became smaller and smaller, the length of gates became smaller and smaller, and the industry began to measure it in nanometers.</b></p><p>The key node about the change of process naming appeared in 1997.</p><p>\"With technological advances and the emergence of other innovative technologies such as strained silicon, faster, cheaper and more energy-efficient becomes equally important in addition to shrinking transistors.\" Kissinger believes that from this point on,<b>Traditional naming methods no longer match the actual transistor gate length.</b></p><p><b>In other words, transistor size is not the only determinant to some extent, and factors such as the \"interconnection\" between them cannot be ignored.</b></p><p>In 2011, after Intel launched FinFET transistor structure technology, the industry was further differentiated. It's an entirely new way to build transistors, with unique shapes and structures.</p><p>This structure is the key technology to continue to indent the stagnant 22nm.<b>But it must be clear that starting from 22nm, not to mention the public, even the industry's understanding of process numbers has gradually deviated from its actual \"coordinates\".</b></p><p><b>This is also the fundamental reason why Intel has established a new naming system.</b></p><p>As Tiger Sniff got the answer when interviewing engineers before: \"Intel is relatively more radical and demanding in formulating manufacturing process standards. But it is true that the manufacturing process has been delayed by 1 to 2 years. Saying that they are lagging behind does not mean that they have no possibility of catching up.\" But Intel's drastic process this time<b>rename</b>，<b>Maybe it's not that I don't believe myself, but that I smell the cruel reality that the market and capital have been confused by \"naming\" for a long time (such as the beginning), and even make business judgments based on it.</b></p><p>However, we thought of a question-even if a newly named product is launched, there is no reason for customers not to ask: \"How many nanometers is your intel7? How many nanometers is the benchmark of TSMC?\"</p><p>To be honest, we want to know how Intel answers this question when encountered.</p><p>Defend Moore's Law to the death?</p><p>At this extremely detailed \"process technology science popularization meeting\", Kissinger mentioned at least three times that \"Moore's Law will not die out, and Intel will continue to continue Moore's Law through various methods, such as changing materials, transistor structures, and packaging.\"</p><p>To be honest, apart from this meaningful new naming system,<b>Intel's most interesting and most noteworthy product is undoubtedly Intel20A after Intel3.</b></p><p>(Of course, Intel4 will also attract much attention as the first batch of processors to apply ASML's High-NA extreme ultraviolet radiation lithography (EUV) technology, but its symbolic significance is not as good as Intel20A.)</p><p>The reason why Intel 20A (5nm) is called the next watershed in the development of process technology in history by Intel is because it is the first chip to apply Intel's two \"pioneering technologies\":</p><p><ul><li><b>Gate-All-Around, a new transistor architecture to replace FinFET (Intel named it RibbonFET)</b></p><p></li><li><b>PowerVia, a power transmission system that can solve the \"interconnection bottleneck\".</b></p><p></li></ul>There is no need to elaborate on the importance of FinFET technology.</p><p>It is a 3D transistor technology (fin transistor) developed by Hu Zhengming, a professor of electrical engineering and computer science at the University of California, Berkeley, in 1999. The reason why Intel was able to take the lead in mass-producing 22nm transistors 12 years later was that TSMC and Samsung smoothly transitioned to the 16/14 nm process node, and FinFET contributed a lot.</p><p>It was this \"invention\" that enabled Moore's Law to \"extend its life\" for decades.</p><p>However, as the manufacturing process continues to shrink from 5nm to 3nm, semiconductor manufacturing experts have found that further reducing the size of FinFETs is increasingly limited by driving current and static control.</p><p>The Gate All Around that will replace it is commonly called GAAFET (Full Gate Field Effect Transistor), which uses a ribbon channel surrounded by the gate to achieve faster transistor switching speed and better control. Therefore, higher performance can be achieved in a smaller footprint. Samsung announced in 2020 that it would apply this architecture on 3nm process chips.</p><p><img src=\"https://static.tigerbbs.com/6a6fca1343877c136cbeef1a4caedada\" tg-width=\"1000\" tg-height=\"255\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image from Lam Semiconductor</p><p>Unlike FinFETs, in which higher currents require multiple side-by-side fins; The current carrying capacity of GAA transistors is mainly improved by stacking several nanosheets vertically (above), while the gate material is mainly wrapped around the channel.

But the reason why it is not \"reused\" by the industry is,<b>The main bottleneck lies in \"materials\"</b>。</p><p>According to the explanation given by Fanlin Semiconductor, GAA transistors are made through the superlattice of \"alternating silicon\" and \"silicon-germanium epitaxial layer\", which is the basis of nanosheets. In addition, the manufacturing process is relatively complicated and may require ruthenium, Molybdenum, nickel and other new alloy materials are deposited, etched, and filled.</p><p>A semiconductor expert summed it up to Huxiu like this: \"It (GAA) will change the base material of the semiconductor, as will the materials connected to the semiconductor. At the same time, the physical structure of the entire transistor will also change.\" Therefore, Dr. Sanjay Natarajan, who led the team to develop this technology, called Intel's GAA-RibbonFET a \"major leap in transistor performance\", which is not false.</p><p>Based on the test chip results, they predict that the performance and density improvement brought by RibbonFET transistors will exceed that of current FinFET transistors.

The attitude of semiconductor companies has shown amazing consistent changes:</p><p>Except for competitors stepping on the way like watching the excitement, this \"critical trend\" seems to evolve into-<b>The days remaining for the top semiconductor giant seem numbered.</b></p><p>The crisis encountered at the level of technological innovation has also spread to their financial data.

Although it attracted the attention of the industry with its generous and \"never giving up manufacturing\" attitude, it continued to be controversial because of its poor financial report;</p><p>Yesterday, four senior Intel manufacturing technology experts, including CEO Kissinger, once again disclosed Intel's process technology and implementation path on a large scale.<b>A \"new bomb\" was dropped on the semiconductor industry:</b></p><p><ul><li>Intel does have delays at 10nm and 7nm (if you are interested, you can read my article \"Intel Abdicates, TSMC Becomes King\"), but on the 5nm node, Intel believes that instead of delaying, it will complete the transcendence.</p><p></li></ul><ul><li>In order to deal with the \"false propaganda of manufacturing processes\" by rivals such as TSMC and correct everyone's misunderstanding of manufacturing processes, Intel directly abandoned the statement of \"10nm, 7nm, 5nm, 3nm\" that is essentially determined by Moore's Law, and directly adopted 100% Intel's new naming system from a subjective perspective-Intel7, Intel4, Intel3, Intel20A, Intel18A.</p><p></li></ul><ul><li>The Intel20A disclosed this time essentially corresponds to the 5nm process.<b>This is a manufacturing process node that Intel has kept silent about for the past two years, and the relevant time plan basically ended abruptly at 7nm.

Among them, this process will use a new transistor structure Gate-All-Around, which is not a FinFET structure that has made great contributions to the productization of processes below 22nm.</p><p></li></ul>In other words, this new structure chip using new materials will bring about major changes to the traditional process concept. Just like a semiconductor technology expert told Tiger Sniff: \"This new material structure and the manufacturing process are a few nanometers or so, it doesn't matter so much.\"</p><p><b>Intel's new process naming system: Wake up, customers</b></p><p>The naming of the manufacturing process has been criticized by the industry for a long time.</p><p>For example, we once mentioned in the article \"Intel Abdicates, TSMC Becomes King\" that many engineers in the industry believe that Intel has a more realistic attitude towards \"nano\" process numbers, and even said that \"Intel's 10nm chip benchmark is actually TSMC's 7nm, even better than the latter's 7nm.\"</p><p>This is why Kissinger has repeatedly called on everyone to correctly understand \"process numbers\" in public after taking office:</p><p>\"Including Intel, different process node naming and numbering schemes are used. These schemes neither refer to any specific measurement method nor fully demonstrate how to achieve the best balance of chip energy efficiency and performance.\" This is like those cars at auto shows that claim to have reached hundreds of thousands of Tops in their chips, and it is also like the \"Autonomous Driving Takeover Report\" released by California every year-without uniform test conditions and sufficient corporate integrity, it is absolutely unworthy of saying \"Who performs better than whom\" conclusion.</p><p>Therefore, Intel has made great efforts to change the naming system this time, saying: \"Let customers have a more accurate understanding of the evolution of process nodes in the entire industry, and then make more informed decisions.\"<b>In fact, the main purpose is to deal with the less reliable 5nm and 3nm process names of TSMC and Samsung.</b></p><p><ul><li>The Intel 7, which will be launched in the second half of 2021 (does it at least look like 7nm?), is actually the 10nm Enhanced SuperFin previously released by Intel;</p><p></li></ul><ul><li>The Intel 4 released in the first half of 2023 (at least it looks like 4nm?), is actually the 7nm of Intel's previous PPT;</p><p></li></ul><ul><li>The Intel3 released in the second half of 2023 is actually the 7nm + on Intel's previous PPT;</p><p></li></ul><ul><li><b>Intel20A released in the first half of 2024 (does it look like 2nm?), is actually 5nm under Intel standards;</b></p><p></li></ul><ul><li>Intel18A will be released in the first half of 2025, which is actually 5nm + under Intel standards.</p><p></li></ul><img src=\"https://static.tigerbbs.com/1ce380fc9b07caca9a43fa165a2e90a8\" tg-width=\"1000\" tg-height=\"471\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image via Intel</p><p>In fact, with the increasing complexity of transistor structures, as early as the beginning of the 21st century, the industry began to have a \"differentiation trend\" in the naming of nanometer processes of chips.</p><p>As we all know, microprocessors are made up of billions of transistors connected in a specific way. These transistors act as \"switches\" and are responsible for processing the ones and zeros of electronic data.</p><p>Kissinger explained that there is an area at the top of the transistor called the \"gate\", which determines whether the transistor is turned on or off. The \"process node\" refers to a complex scheme consisting of thousands of manufacturing steps required for transistors.</p><p>And almost all the top semiconductor companies have the same goal-to make these chips smaller, faster, cheaper, and more energy-efficient-the best example is Apple's 5nm process chip M1 (there are too many reviews about M1 You can see the review, I also bought an M1 Macbook Air, and I can't put it down).</p><p><img src=\"https://static.tigerbbs.com/ae99fc8b1663fb184dc959320da5b5a1\" tg-width=\"1000\" tg-height=\"384\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Initially, the name of the process process \"node\" corresponded to the gate length of the transistor and was measured in \"microns\".<b>As transistors became smaller and smaller, the length of gates became smaller and smaller, and the industry began to measure it in nanometers.</b></p><p>The key node about the change of process naming appeared in 1997.</p><p>\"With technological advances and the emergence of other innovative technologies such as strained silicon, faster, cheaper and more energy-efficient becomes equally important in addition to shrinking transistors.\" Kissinger believes that from this point on,<b>Traditional naming methods no longer match the actual transistor gate length.</b></p><p><b>In other words, transistor size is not the only determinant to some extent, and factors such as the \"interconnection\" between them cannot be ignored.</b></p><p>In 2011, after Intel launched FinFET transistor structure technology, the industry was further differentiated. It's an entirely new way to build transistors, with unique shapes and structures.</p><p>This structure is the key technology to continue to indent the stagnant 22nm.<b>But it must be clear that starting from 22nm, not to mention the public, even the industry's understanding of process numbers has gradually deviated from its actual \"coordinates\".</b></p><p><b>This is also the fundamental reason why Intel has established a new naming system.</b></p><p>As Tiger Sniff got the answer when interviewing engineers before: \"Intel is relatively more radical and demanding in formulating manufacturing process standards. But it is true that the manufacturing process has been delayed by 1 to 2 years. Saying that they are lagging behind does not mean that they have no possibility of catching up.\" But Intel's drastic process this time<b>rename</b>，<b>Maybe it's not that I don't believe myself, but that I smell the cruel reality that the market and capital have been confused by \"naming\" for a long time (such as the beginning), and even make business judgments based on it.</b></p><p>However, we thought of a question-even if a newly named product is launched, there is no reason for customers not to ask: \"How many nanometers is your intel7? How many nanometers is the benchmark of TSMC?\"</p><p>To be honest, we want to know how Intel answers this question when encountered.</p><p>Defend Moore's Law to the death?</p><p>At this extremely detailed \"process technology science popularization meeting\", Kissinger mentioned at least three times that \"Moore's Law will not die out, and Intel will continue to continue Moore's Law through various methods, such as changing materials, transistor structures, and packaging.\"</p><p>To be honest, apart from this meaningful new naming system,<b>Intel's most interesting and most noteworthy product is undoubtedly Intel20A after Intel3.</b></p><p>(Of course, Intel4 will also attract much attention as the first batch of processors to apply ASML's High-NA extreme ultraviolet radiation lithography (EUV) technology, but its symbolic significance is not as good as Intel20A.)</p><p>The reason why Intel 20A (5nm) is called the next watershed in the development of process technology in history by Intel is because it is the first chip to apply Intel's two \"pioneering technologies\":</p><p><ul><li><b>Gate-All-Around, a new transistor architecture to replace FinFET (Intel named it RibbonFET)</b></p><p></li><li><b>PowerVia, a power transmission system that can solve the \"interconnection bottleneck\".</b></p><p></li></ul>There is no need to elaborate on the importance of FinFET technology.</p><p>It is a 3D transistor technology (fin transistor) developed by Hu Zhengming, a professor of electrical engineering and computer science at the University of California, Berkeley, in 1999. The reason why Intel was able to take the lead in mass-producing 22nm transistors 12 years later was that TSMC and Samsung smoothly transitioned to the 16/14 nm process node, and FinFET contributed a lot.</p><p>It was this \"invention\" that enabled Moore's Law to \"extend its life\" for decades.</p><p>However, as the manufacturing process continues to shrink from 5nm to 3nm, semiconductor manufacturing experts have found that further reducing the size of FinFETs is increasingly limited by driving current and static control.</p><p>The Gate All Around that will replace it is commonly called GAAFET (Full Gate Field Effect Transistor), which uses a ribbon channel surrounded by the gate to achieve faster transistor switching speed and better control. Therefore, higher performance can be achieved in a smaller footprint. Samsung announced in 2020 that it would apply this architecture on 3nm process chips.</p><p><img src=\"https://static.tigerbbs.com/6a6fca1343877c136cbeef1a4caedada\" tg-width=\"1000\" tg-height=\"255\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>Image from Lam Semiconductor</p><p>Unlike FinFETs, in which higher currents require multiple side-by-side fins; The current carrying capacity of GAA transistors is mainly improved by stacking several nanosheets vertically (above), while the gate material is mainly wrapped around the channel. The size of the nanosheets can be scaled so that the transistors can be tuned to the specific performance required.</p><p>It sounds like the concept of \"nanosheets\" is actually not so difficult to understand; And in fact, this technology has been developed for many years. But the reason why it is not \"reused\" by the industry is,<b>The main bottleneck lies in \"materials\"</b>。</p><p>According to the explanation given by Fanlin Semiconductor, GAA transistors are made through the superlattice of \"alternating silicon\" and \"silicon-germanium epitaxial layer\", which is the basis of nanosheets. In addition, the manufacturing process is relatively complicated and may require ruthenium, Molybdenum, nickel and other new alloy materials are deposited, etched, and filled.</p><p>A semiconductor expert summed it up to Huxiu like this: \"It (GAA) will change the base material of the semiconductor, as will the materials connected to the semiconductor. At the same time, the physical structure of the entire transistor will also change.\" Therefore, Dr. Sanjay Natarajan, who led the team to develop this technology, called Intel's GAA-RibbonFET a \"major leap in transistor performance\", which is not false.</p><p>Based on the test chip results, they predict that the performance and density improvement brought by RibbonFET transistors will exceed that of current FinFET transistors. Intel 20A will be the first chip to apply RibbonFET.</p><p><img src=\"https://static.tigerbbs.com/e0a40c6ececaec4fa8741e6781f30b32\" tg-width=\"1000\" tg-height=\"487\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>The power transmission system PowerVia is a unique technology developed by Intel engineers.

By reducing the power wiring on the front of the wafer, more \"open space\" is freed up to optimize signal wiring and reduce delay to achieve better power transmission.</p><p><img src=\"https://static.tigerbbs.com/711724a13d34832717d6e33d027d163f\" tg-width=\"1000\" tg-height=\"603\" referrerpolicy=\"no-referrer\" width=\"100%\" height=\"auto\"></p><p>It is worth noting that although these two key technologies to be used in Intel20A are inevitably criticized as \"still in PPT state\" (after all, they are still PPT), Intel experts showed the scanning electron microscope images of these test chips, obviously after a series of tests.</p><p>As mentioned above, their successful application will determine whether Intel can overtake at the key node of 5nm.</p><p>From the time point of view, it is obvious that the \"realization of 7nm + + in 2023\" planned on the PPT in 2019 is not much apart from the \"realization of Intel20A in 2024\" planned this time.

IC Insights发布的《2021年Q1全球Top15半导体公司业绩与排名》指出，英特尔虽然位列第一，但却是所有厂商中唯一一家营收下滑的企业。\n\n图片来自IC Insights\n英特尔当然焦虑。这种焦虑可能体现在：\n\n受到资本市场巨大压力，2021年年初突然换帅，重新启用有40年制造技术履历的帕特·基辛格(Pat Gelsinger)为新任CEO。\n\n\n迅速接受了阿斯麦比自己更为先进的EUV制造工艺，用了大约两个季度的时间修复了7nm技术。\n\n\n在制造环节投入巨资。今年3月，帕特·基辛格正式公布十分关键的“IDM 2.0”战略，宣布重返晶圆代工市场，同时宣布投资200亿美元在美国亚利桑那州新建两座晶圆厂；5月再次宣布，投资35亿美元升级新墨西哥州工厂，投资100亿美元在以色列兴建的芯片厂，还计划在欧盟建厂。\n\n\n越来越多的英特尔半导体技术专家现身说法，为自己的制造技术正名，强调“每家晶圆厂的制程数据有对外宣传的差异”。\n\n当然，根据虎嗅平台的观察和媒体反应，在国内大大小小的人工智能、物联网以及数据中心市场活动上，你能越来越多次看到英特尔出现的身影。\n\n英特尔 CEO 帕特·基辛格\n以重新夺回“制程节点”为目标的英特尔，今年3月发布的“IDM2.0战略”就以大手笔和”绝不放弃制造”的态度虽然引起产业重视，但因为表现不佳的财报状况持续受到争议；\n而昨天，包括CEO基辛格在内的4位英特尔高级制造技术专家，再次通过大范围公开英特尔的制程技术和实现路径，向半导体产业投掷了一枚“新炸弹”：\n\n英特尔的确在10nm和7nm有所延迟（如果感兴趣，可以看我的这篇文章《英特尔退位，台积电称王》），但在5nm节点上，英特尔自认为非但没有延迟，反而会完成超越。\n\n\n为了应对台积电等对手的“制程虚假宣传”，以及纠正大家对制程的认知误区，英特尔直接舍弃了“10nm，7nm，5nm，3nm”这一本质上由摩尔定律决定的说法，而是直接采用100%英特尔主观视角的新命名体系——Intel7，Intel4，Intel3，Intel20A，Intel18A。\n\n\n这一次公开的Intel20A，本质对应的就是5nm制程。这是一个英特尔近2年来闭口不谈的制程节点，相关时间计划基本到7nm就戛然截止了。英特尔首次宣布将通过Intel20A，进入“埃米时代”。\n\n\nIntel20A背后两大关键技术非常值得注意。其中，这个制程将会采用全新的晶体管结构Gate-All-Around，并非是为22nm以下制程产品化立下汗马功劳的FinFET结构。\n\n换言之，这种应用了新材料的新结构芯片，将会对传统制程概念，产生重大改变。就如一位半导体技术专家告诉虎嗅：“这种新的材料结构，制程这些几纳米啥的就没那么大的关系了。”\n英特尔新制程命名体系：快醒醒，客户们\n关于制程的命名问题，被产业诟病已久。\n譬如我们曾在《英特尔退位，台积电称王》这篇文章里提及，业内不少工程师认为，英特尔在对待“纳米”制程数字的态度更实在，甚至表示“英特尔的10nm芯片对标的其实是台积电的7nm，甚至比后者的7nm都好”。\n这也是基辛格上任后，多次在公开场合呼吁大家正确理解“制程数字”：\n\n “包括英特尔在内，使用着各不相同的制程节点命名和编号方案，这些方案既不指代任何具体的度量方法，也无法全面展现如何实现芯片能效和性能的最佳平衡。”\n\n这就像是车展上那些号称自己芯片达到几百几千Tops的汽车，也像是加州每年发布的《自动驾驶接管报告》——没有统一测试条件和足够的企业诚信度，就绝对不配说出“谁比谁性能好”的结论。\n所以，英特尔这次兴师动众地更换了命名体系，美名曰：“让客户对整个行业的制程节点演进有一个更准确认知，进而做出更明智的决策”，其实主要目的就是对付台积电和三星不那么太靠谱的5nm和3nm制程名字。\n\n2021年下半年将推出的Intel 7 （是不是至少看起来像是7nm？），其实就是英特尔之前发布的10nm Enhanced SuperFin；\n\n\n2023年上半年发布的Intel 4（至少看起来像4nm？），其实就是英特尔之前PPT的7nm；\n\n\n2023年下半年发布的Intel3，其实就是英特尔之前PPT上的7nm+；\n\n\n2024年上半年发布的Intel20A（看起来像不像2nm？），其实就是英特尔标准下的5nm；\n\n\n2025年上半年发布Intel18A，其实就是英特尔标准下的5nm+。\n\n\n图片来自英特尔\n实际上，随着晶体管结构的愈加复杂，早在21世纪初，产业内就开始对芯片的纳米制程命名有了“分化趋势”。\n我们都清楚，微处理器是由以特定方式连接起来的数十亿晶体管组成。这些晶体管充当了“开关”的角色，负责处理电子数据的1和0。\n基辛格解释，在晶体管顶部有一个区域叫“栅极”，它决定了晶体管是开启还是关闭。而“制程节点”指代的是晶体管所需的数千个制造步骤组成的复杂方案。\n而所有最顶级半导体公司几乎都有同一个目标——让这些芯片变得更小、更快、更便宜、更高能效——最好的例子莫过于苹果的5nm制程芯片M1（有太多关于M1的测评可以去看，我也买了一台M1的Macbook Air，爱不释手）。\n\n最初，制程工艺“节点”的名称与晶体管的栅极长度相对应，并以“微米”为度量单位。随着晶体管越变越小，栅极的长度越来越微缩，产业开始以纳米为度量单位。\n而关于制程命名改变的关键节点出现在1997年。\n“随着技术进步和应变硅（strained silicon）等其他创新技术的出现，除了缩小晶体管，更快、更便宜和更高能效也变得同样重要。” 基辛格认为，从这时开始，传统命名方法不再与实际的晶体管栅极长度相匹配。\n换言之，晶体管尺寸在某种程度上不是唯一的决定因素，它们之间的“互连”等因素也不能忽略。\n2011年，在英特尔推出FinFET晶体管结构技术后，行业进一步分化。这是一种构建晶体管的全新方式，具有独特的形状和结构。\n这个结构就是将停滞不前的22nm继续往下缩进的关键技术。但要很显然，从22nm开始，不要说大众，就连产业内对制程数字的理解与它的实际“坐标”也开始逐渐脱离。\n这也是英特尔如今建立新命名体系的根本缘由。\n\n 正如虎嗅之前在采访工程师时得到的答案：“英特尔在制造工艺标准制定上相对更激进，要求也更高。但的确制程延迟了1~2年，说落后并不意味着他们没有追赶的可能性。”\n\n但英特尔这次大刀阔斧的制程更名，也许不是不相信自己，而是嗅到了市场和资本已经被“命名”困惑已久（譬如开头），甚至依此来做出商务判断的残酷现实。\n不过我们想到了一个问题——即便推出了新命名产品，客户没有理由不问一句：“你这intel7到底几纳米？对标的是台积电的几纳米？”\n说实话，我们更想知道英特尔在遇到这个问题时怎么回答。\n誓死捍卫摩尔定律？\n基辛格在这次可谓是极为详尽的“制程技术科普会”上，至少提了三次关于“摩尔定律不会消亡，英特尔会通过各种方法，如改材料、晶体管结构，以及封装等角度，继续来延续摩尔定律”的决心。\n实话讲，除了这个意味深长的新命名体系，英特尔最有趣且最应该受到关注的产品，毫无疑问是Intel3之后的Intel20A。\n（当然，Intel4 将作为第一批应用阿斯麦高数值孔径（High-NA）极紫外辐射光刻技术(EUV)的处理器也倍受瞩目，但象征意义不如Intel20A。）\nIntel 20A（5nm）之所以被英特尔称为历史上制程技术发展的下一个分水岭，是因为它是第一块应用英特尔两大“开创性技术”的芯片：\n\n替代FinFET的全新晶体管架构 Gate-All-Around（英特尔把它命名为RibbonFET）\n能够解决“互联瓶颈”的电能传输系统PowerVia。\n\nFinFET技术的重要性已经无须赘述。\n它是加州伯克利大学电子工程与计算机专业教授胡正明在1999年研发出的 3D 晶体管技术（鳍型晶体管）。英特尔之所以能在 12 年后率先量产出 22nm 晶体管，台积电与三星顺利过渡至 16/14nm 制程节点，FinFET功不可没。\n正是这项“发明”，摩尔定律才得以“延寿”数十年。\n但是，随着制程从5nm持续缩进至3nm，半导体制造专家们发现，进一步减少 FinFET 尺寸，就越来越受到驱动电流和静电控制的限制。\n而将要替代它的Gate All Around的常用名为GAAFET（全栅场效应管），它使用栅极包围的带状通道，从而能实现更快的晶体管切换速度和更好的控制。因此，在更小的占用空间内，可具备更高的性能。三星在2020年曾宣布将在3nm制程芯片上应用这一架构。\n\n图片来自泛林半导体\n与 FinFET不同的是，在 FinFET 中，较高电流需要多个并排的鳍片；GAA 晶体管的载流能力主要是通过垂直堆叠几个纳米片（上图），而栅极材料主要是包裹在沟道周围来提高的。纳米片的尺寸可以按比例缩放，以便晶体管可以按照要求的特定性能进行调整。\n听起来，“纳米片”的概念其实理解起来并不是那么困难；而且实际上，这项技术已经被研发多年。但其之所以不受业内“重用”，主要瓶颈就在于“材料”。\n根据泛林半导体给出的解释，GAA晶体管是通过“交替硅”和“硅锗外延层”的超晶格来制作的，这是构成纳米片的基础，此外制作工艺相对复杂，可能需要钌、钼、镍等各种合金新材料进行沉积、蚀刻、填充。\n\n 一位半导体专家这样给虎嗅总结：“它（GAA）将对半导体的基底材料进行更改，半导体连接的材料也要进行更改。同时整个晶体管的物理结构也要变化。”\n\n因此，带领团队开发这项技术的Sanjay Natarajan博士将英特尔的GAA——RibbonFET称为一次“晶体管性能上的重大飞跃”，并非虚话。\n根据测试芯片结果，他们预计RibbonFET晶体管带来的性能和密度提升，将超过当下的FinFET晶体管。而Intel 20A将是应用RibbonFET的第一枚芯片。\n\n而电能传输系统PowerVia则是英特尔工程师开发的一项独特技术。Sanjay Natarajan博士作为这项技术的开发负责人，指出半导体晶体管结构中存在的最大传统问题之一便是“布线效率低下”。\n“传统互连技术是在晶体管层的顶部进行互联，经常产生电源线和信号线的互混，导致了布线效率低下，进而影响性能和功耗。”\n他们的解决方法，便是把电源线置于晶体管层的下面（也就是晶圆的背面）。通过减少晶圆正面的电源布线，腾出更多的“空地儿”用于优化信号布线，并减少时延，实现更好的电能传输。\n\n值得注意的是，这两项将用于Intel20A的关键技术，虽然不可避免被人诟病为“仍然处于PPT状态”（毕竟还都是PPT），但英特尔的专家们展示了这些测试芯片的扫描电镜图像，显然经过了一系列测试。\n就像上面所说，它们的成功应用，将决定着英特尔是否能在5nm这个关键节点上进行反超。\n从时间来看，很明显，2019年时PPT上规划的“2023年实现7nm++”，与这次规划的“2024年实现Intel20A”没有多少间隔。也就是说，依然有机会在5nm这个节点上翻盘。\n\n英特尔2019年10月的制程产品规划图\n如基辛格所说，英特尔Intel20A在2024年的问世与两大关键技术的真正应用，将标志着半导体“埃米时代”（1埃米=0.1纳米）的启幕。\n现在来听，其实更像是英特尔在向外界喊话：你们以为我还想在“纳米时代”争夺领导权？不，我们要进入一个比纳米更小的单位去争夺话语权了。\n写在最后…希望不是PPT\n但话说回来，既然完全改变了以纳米为单位的命名体系，而且晶体管结构和材料正在发生下一轮巨大变化。此外，英特尔也在从封装技术层面提高芯片的带宽密度和能效……\n这一切难道不是意味着，所谓的纳米还是埃米的数字单位，已经越来越没意义了吗？\n英特尔嘴上说在捍卫摩尔定律，其实已经认识到不能再依靠摩尔定律。\n如今，Intel20A的制造工艺虽然官方说拿下了高通这个大订单，但距离2024年变数还有很大。我们虽然觉得英特尔这场发布会的意义重大，并且产品规划让人没有异议，但是PPT能够转变称真正的产品，还是需要实物说话。\n毕竟，当年延迟了4年的14nm产品，当时PPT做的也挺不错的。","news_type":1,"symbols_score_info":{"TSM":0.9,"EWT":0.9,"03145":0.9,"INTC":0.9,"03086":0.9,"09086":0.9,"TWmain":0.9}},"isVote":1,"tweetType":1,"viewCount":2275,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":808087297,"gmtCreate":1627544729719,"gmtModify":1703492037799,"author":{"id":"3586587763605977","authorId":"3586587763605977","name":"程導绅","avatar":"https://static.tigerbbs.com/17e557db7a706e6821394c3f5dc700d2","crmLevel":1,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3586587763605977","idStr":"3586587763605977"},"themes":[],"htmlText":"Hi","listText":"Hi","text":"Hi","images":[],"top":1,"highlighted":1,"essential":1,"paper":1,"likeSize":0,"commentSize":0,"repostSize":0,"link":"https://ttm.financial/post/808087297","repostId":"2155908504","repostType":4,"repost":{"id":"2155908504","kind":"news","pubTimestamp":1627544101,"share":"https://ttm.financial/m/news/2155908504?lang=en_US&edition=fundamental","pubTime":"2021-07-29

In addition, the market has very full expectations for the Fed to withdraw from easing, so it will not happen again in February-March at the beginning of the year. The situation that the upward trend of US Treasury yields has caused a serious impact on the equity market.
