INTEL 32NM的contached gate pitch小于TSMC和IBM的28NM是不是因为INTEL的design rule比较特别?
Roy.Yu 17:36:14
性能要求不一样,所有design rule要求也不一样
Roy.Yu 17:36:45
一般而言,intel的工艺比foundry的下一代还要tight
Roy.Yu 17:37:04

At IEDM, Intel manager Paul Packen said Intel's flagship 32 nm technology achieved record drive current levels, with the PMOS transistor showing a 35% drive current improvement over the 45 nm PMOS device. "For the first time, linear drive currents on the PMOS have overtaken NMOS," he said. The sharp gain in PMOS performance comes partly by adding germanium to the SiGe stressors, and from the replacement-gate process.
Intel Corp. presented details on its 32 nm logic technology at the International Electron Devices Meeting (IEDM), reporting that its fourth-generation strain techniques have boosted the PMOS performance to a historic point. "For the first time, linear drive currents on the PMOS have overtaken NMOS," said Paul Packan, 32 and 15 nm technology programs manager.

For the oft-quoted saturated drive current, the 32 nm NMOS value remains higher, at 1.62 mA/μm Idsat compared with 1.37 mA/μm for the 32 nm PMOS transistor. Packan said the PMOS linear drive current (ldlin) reached 0.24 mA/μm, a 35% improvement over the 45 nm PMOS transistor. The NMOS device Idlin gained a 20% improvement, partly from a raised source-drain architecture, reaching a linear drive current of 0.231 mA/μm. Linear drive current is important because transistors rarely get to full saturation, making Idlin a meaningful metric for real-world device operation.

With NMOS and PMOS now in rough parity, designers can adjust the size of the PMOS transistors to their needs, said Mark Bohr, a senior fellow at Intel. "For many generations, there was a 2:1 ratio between the NMOS and PMOS," largely caused by inherently different mobilities between electrons and holes. "At the 32 nm generation, our saturation and linear drive currents are closer to being matched; we are getting very close." That means for the Westmere processor Intel designers could create circuits with smaller PMOS transistors in some cases, Bohr said.
The sharp gain in PMOS performance comes partly by adding more germanium to the SiGe stressors, to a 40% level. Also, "we are moving the SiGe closer to the channel at the 32 nm generation, which is challenging at these dimensions," Bohr said.

The replacement gate technique adds another boost, rivaling that of the SiGe stressors. Before high-k/metal gate technology was introduced, the polysilicon electrode was neutral in terms of strain on the PMOS channel. With the replacement gate, or gate-last, technology, removal of the sacrificial gate allows the SiGe stress regions to exert a stronger tensile strain on the channel, reaching 2 GPaFor the NMOS, the raised source and drain reduces resistance, "helping to mitigate the pitch scaling issues," Packan said. By moving transistors closer together, there is less room for stress regions. Though in previous interviews Bohr has not been positive about the value of SiC stressors on the NMOS channel, he declined to comment on whether Intel is using SiC at the 32 nm node.

Although Intel remains on a Moore's Law pace in terms of contact gate pitch scaling, with a 112.5 nm pitch, shrinking is no longer delivering the speed improvements seen in past generations, Packan said. With smaller dimensions, less material can be deposited to add strain. And threshold voltages have crept up slightly in recent years at the same Ioff levels.

"Traditional scaling is losing steam," Packan told the standing-room-only Wednesday IEDM session on leading-edge CMOS. He estimated that were it not for the additional benefits of higher strain, performance actually would have declined for the 32 nm transistors. One reason, Bohr said, is that to counter short channel effects in the aggressively scaled gates the channel must receive higher dopant levels, causing threshold voltages to rise and slowing down the transistor.

"We need a new paradigm for performance improvement," Packan said.

Though several participants at IEDM said CMOS scaling is likely to slow to a three-year pace, Bohr said Intel plans to stay on a two-year cadence. The Westmere processors are shipping now from two Intel fabs to computer vendors, and the 22 nm technology is on pace to ship two years later. Not only does Intel want to remain ahead of its MPU competition, its computer customers need faster MPUs every two years so they can sell new systems to their customers, he said.

Abstract
This work presents a 32 nm SOI CMOS technology featuring high-k/metal gate and an SRAM cell size of 0.149 mum2. Vmin operation down to 0.6 V in a 16 Mb SRAM array test vehicle has been demonstrated. Aggressive ground rules are achieved with 193 nm immersion lithography. High performance is enabled by high-k/metal gate plus innovation on strained silicon elements including embedded SiGe and dual stress liner (DSL). Gate lengths down to 25 nm have been demonstrated enabling performance without the power penalty from gate capacitance. AC drive currents of 1.55 mA/um and 1.22 mA/um have been achieved at an off-state of 100 nA/mum and VDD of 1 V for NFET and PFET, respectively. For the first time, we have also demonstrated that SOI maintains performance benefit over bulk silicon in high-k/metal gate and 32 nm ground rules.

    所谓高性能的45NM,EOT相当于INTEL的90NM,电气性能是在at 1.0V and 200nA/um Ioff.得出的,而且PMOS性能不行。gate-first就是这儿搞不下去。所以这款45NM仅仅是研究用的
作者: PRAM    时间: 2010-9-20 20:59
For AMD, the goal was not only to shrink the physical dimensions but also to increase performance. Scaling transistors means better performance, but most of the dimensional scaling at 45 nm is related to gate and metal pitches rather than to length of the transistor gate or channel. The minimum gate length on Shanghai is 38 nm—a reduction of only seven percent from the 65-nm node. But the transistor performance is 19 percent better for the NFET and 23 percent better for the PFET compared with 65-nm generation transistors.


How'd they do that? The answer, in a word, is optimization. Although there are no new materials or techniques like adding an additional stressor for strained silicon engineering, AMD improved transistor performance by squeezing every last drop out of the performance-enhancing structures already in use at 65 nm. As usual, the starting point was a silicon-on-insulator (SOI) wafer as opposed to the bulk wafer technology used elsewhere. The rest of the transistor performance story relates to strain engineering.



On the NFET side, stress memorization stretches the n-channel, which is enhanced later in the process flow by the addition of a nitride tensile stress liner. The liner itself is scaled down at 45 nm to ensure the required strain is adequately supplied to the transistor channel to enhance electron mobility and subsequently increase the drive current. The gate-stack design is modified as well, with a new sidewall spacer design for 45nm.



The PFET performance improvement is more dramatic with drive current now up to 660 µA/µm compared with 510 µA/µm on 65-nm transistors.
Again, this increased output current is the result of optimized compressive strain for the p-channel device. The new design of the PFET moves the embedded silicon-germanium source/drain regions closer to the channel to maximize the transfer of stress, thereby increasing hole mobility. Although shorter gate lengths are not driving the improvements, it is a reduction in dimensions that allows increased channel stress to provide the performance scaling. AMD 45-nm PFET design reduces the space from embedded

We all want our Google results to come fast, so server-chip speed is important. Intel has a long history of pushing processor-speed performance ratings, and did so by designing transistors with high on currents to drive fan out gates quickly. In fact, Intel's 45-nm high-K metal gate transistors have the best peak drive currents on the market with 1.36µA/µm for NFETs and just over a milliamp for PFETs. Compared with Intel's speed-burners, a typical 45-nm transistor on AMD's Shanghai is a lot less powerful. I know very little about CPU benchmarks let alone server tests, but I know the speed performance for a Shanghai-based server would be limited at some point by the lower drive current available from the AMD 45-nm transistors.
The transistor drive current for AMD's 45-nm devices is much lower than that of the Intel HKMG transistors.

    拿一个不量产的东西吹有意义---------------------Molten silicon and atomic radiation are two of the hazards Intel is confronting in its race to make faster circuits, the company said on Friday at the International Electron Devices meeting in Washington DC.

As part of this battle it unveiled a new design for transistors, one of which it says will operate at speeds hundreds of times faster than today's production devices.

The terahertz transistor design -- a terahertz is a thousand gigahertz, or one trillion cycles a second -- is an evolution of current designs, using new materials such as zirconium dioxide. Smaller transistors go faster but also leak more current when turned off and need a higher voltage to work; zirconium dioxide is a superior insulator that reduces this leakage and thus reduces power consumption while maintaining speed and low voltages. Intel says that the new design will work down to around 0.6v before long.

Other problems tackled include high capacitance, which increases the power needed to turn the transistor on and slows it down, and radiation from the atmosphere and packaging, which injects electrons directly into the transistor and causes a "soft error" in memory or logic designs. These have been minimised by putting the transistor on a sheet of insulator, which shields the effects of the radiation.

It also reduces the amount of conductor present near the transistor thus reducing the capacitance. Intel's new design reduces the number of electrons left floating around after the transistor operates, making the design more consistent.

Pushing the frontiers of Moore's Law
Without these innovations, it would be extremely difficult to build Pro-Acessor with a billion transistors, which is predicted by Moore's Law to happen by 2007. That design will have 0.045u geometry, two-thirds smaller than that of today, and will operate at around a terahertz. If it weren't for the power reduction inherent in the new design, it could be expected to need around half a kilowatt per square centimetre, a power density higher than that in a nuclear reactor and one that would present a severe challenge to even the most ardent overclocker.

intel付出了怎样的代价------------1.不用昂贵的SOI,导致SOI现在用者寥寥无几  2.由於超越了光學臨近修正(OPC)和設計準則的範疇,英特爾的模型技術功能可以允許使用通常是落後一個世代的設備,來製造當代的晶片。這樣來說,不僅有較低成本的優勢並且允許使用現有設備來加速進展。以45奈米邏輯製程的關鍵層來說,根據Borodovsky所言,使用193奈米乾式微影取代浸潤式微影將可省下百分之27的成本。让别人的SOI无法普及,浸潤式微影出货量减少,代价太大了

32nm阶段:



IBM/AMD首次使用dual pattern的曝光模式和HKMG。这两者都是相当“昂贵”的,而且不可避免。
注意“浸入式曝光”和“双曝光模式”都是可以使193nm刻更细的线的技术,有趣的是IBM/AMD和intel使用的次序恰相反,只是32nm下将殊途同归。

IBM/AMD的I dsat参数仅略逊于intel(考虑到AC-DC折算),但是EOT却大了不少,所以就性能而言,IBM/AMD公布的数据将有明显优势。如果gate first确实能降低成本,则IBM/AMD可能还有一些成本优势。

IBM强大的都是纸面技术,特許、聯電這批抱IBM大腿的這幾年都被tsmc打得快下海賣身了,更何況有NV多年前給IBM代工的慘痛經驗
,很奇怪不少人喜欢神话IBM,在半导体芯片生产上IBM比intel差十万八千里,IBM的某神话芯片,被用在某游戏机上的,开发团队也正式解散了

在下不是已经说了很多次了? 在下只会一点小学算术,不小心把ibm的废物工艺算得比intel强大工艺还高了那么一点点, 望大人不计小人过,放过在下,去讨伐techreport误导我等外行为宜。

咱是外行,只能看这些外行网站。不过他们数据是copy正式会议的信息,算法也是专家给的 ...

    IBM technology is better than TSMC. However, in the production condition, TSMC is more discipline company; IBM, a research oriented company. Intel discipline is more tough than TSMC. 读不懂这句话的话,请继续YY

    一会说是IBM的PMOS,NMOS性能不如INTEL,EOT却大了不少,所以就性能而言,IBM/AMD公布的数据将有明显优势,一会儿有说Tox更薄性能更好。可是有人就愿意牺牲I dsat和I off换更厚栅氧层有啥不可以?特别是此时I dsat也并不比对手差很多。----这跟小学算术没有关系,是前后逻辑有问题

-阁下所依赖的techreport的结论-------------
    The semiconductor industry is gearing up for a 32nm battle royale, with Intel, IBM, GlobalFoundries, TSMC, and others all prepping competing technologies at the same node. How will they match up? Fresh from the 2008 International Electron Devices Meeting and the 2009 VLSI Symposia, David Kanter of Real World Technologies has posted an in-depth article that seeks to answer that question.

Kanter's comparison includes IBM's high-k metal gate (HKMG) 32nm bulk and silicon-on-insulator processes, which GlobalFoundries should use to manufacture chips for AMD next year. The article also examines TSMC's performance 32nm HKMG process, which should be used to make future graphics processors, and Intel's performance HKMG tech, which we'll see in Clarkdale processors either late this year or in early 2010.

Now, some parts of this piece will probably be well over most readers' heads—unless they happen to have electrical engineering or semiconductor design backgrounds, that is, in which case we expect them to nod their heads slowly and go, "Hmm, yes, very interesting." How else do you expect seasoned engineers to react to graphs like these?

The rest of us might want to skip ahead to page 11, which includes a more accessible and quite interesting overview of the aforementioned processes (plus others from TI and Fujitsu). Here, Kanter comments that IBM's 32nm SOI and Intel's 32nm bulk technologies "have the best transistor performance by a wide margin and with almost identical results." He adds, "This suggests that on paper, Intel, IBM and AMD will be at parity for performance. Although Intel will be in production in late 2009, a year ahead of IBM and AMD."
Kanter makes other interesting observations. Intel's current 45nm process is "ahead of all other production processes," including TSMC's bulk 32nm process. Also, IBM's 32nm bulk process is "closely matched" with TSMC's. That means competition between GlobalFoundries and TSMC at the 32nm node may be quite heated.

要注意的是, IBM's 32nm SOI and Intel's 32nm bulk technologies "have the best transistor performance by a wide margin and with almost identical results指的是INTEL 2008IEDM发表的32NM和IBM 2009年发表的32NM性能相当,INTEL IEDM2009发表的32NM性能又有提升
