TSMC has focused on defect density (D0) reduction for N7. This is why I still come to Anandtech. Again, taking the die as square, a defect rate of 1.271 per cm2 would afford a yield of 32.0%. TSMC illustrated a dichotomy in N7 die sizes mobile customers at <100 mm**2, and HPC customers at >300 mm**2. Nvidia IS on TSMC, but they're obviously using all their allocation to produce A100s. IoT Platform Here is a brief recap of the TSMC advanced process technology status. We anticipate aggressive N7 automotive adoption in 2021., only 7 customers will be able to afford to pursue 7nm designs, and only 5 customers at 5nm. @DrUnicornPhD @anandtech https://t.co/2n7ndI0323, I don't believe I've mentioned this explicitly in public, but I promoted him to Senior CPU Editor last month. Dr. Mii also confirmed that the defect density for N6 equals N7 and that EUV usage enables TSMC . There will be ~30-40 MCUs per vehicle. According to the estimates, TSMC sells a 300mm wafer processed using its N5 technology for about $16,988. TSMC emphasized the process development focus for RF technologies, as part of the growth in both 5G and automotive applications. Like you said Ian I'm sure removing quad patterning helped yields. S is equal to zero. 3nm is half the size of 7nm, that is, Intel's plans to debut its 7nm in late 2022 or early 2023, Best Raspberry Pi Pico Accessories and Add-Ons 2023, Best Raspberry Pi HATs 2023: Expansion Boards for Every Project. That last part is the killer for AMD right now as only 1-2 cores are able to hit rated frequencies and I'm pretty certain its due to quad patterning but do not know that for fact. This node has some very unique characteristics: The figure below illustrates a typical FinFET device layout, with M0 solely used as a local interconnect, to connect the source or drain nodes of a multi-fin device and used within the cell to connect common nFET and pFET schematic nodes. Each year, TSMC conducts two major customer events worldwide the TSMC Technology Symposium in the Spring and the TSMC Open Innovation Platform Ecosystem Forum in the Fall. TSMC was first in the industry to bring 5 nanometer (nm) technology into volume production in 2020 with defect density improving faster than the preceding 7nm generation. Weve updated our terms. Traditional models for process-limited yield are based upon random defect fails, and have stood the test of time over many process generations. TSMC introduced a new node offering, denoted as N6. The N5 process thus ensures 15% higher power or 30% lower consumption and 1.8 times the density of transistors compared to N7. If you are going to talk authoritatively about semiconductor yeild you should at least know that the path to production for a given device is a combination of process-limited yield and design-limited yield.Traditional models for process-limited yield are based upon random defect fails, and have stood the test of time over many process generations. Recent reports state that ASML is behind in shipping its 2019 orders, and plans to build another 25-27 in 2020 with demand for at least 50 machines. 23 Comments. A blogger has published estimates of TSMCs wafer costs and prices. We will support product-specific upper spec limit and lower spec limit criteria. As the semiconductor industry entered the era of sub-wavelength resolution, designers learned of the resolution enhancement technology algorithms that were being applied by the mask house. N6 strikes me as a continuation of TSMCs introduction of a half node process roadmap, as depicted below. From what I understand "3nm" does not necessarily mean what it has traditionally meant and more of a marketing label, perhaps as is mentioned above why the improvements seem underwhelming. Advanced Materials Engineering Inverse Lithography Technology A Status Update from TSMC, TSMCs 28-nm process in trouble, says analyst, Altera Unveils Innovations for 28-nm FPGAs, TSMC Offers the Industrys Most Successful FinFET Technology to Academia, TSMC Holds 3nm Volume Production and Capacity Expansion Ceremony, Marking a Key Milestone for Advanced Manufacturing, TSMC Launches OIP 3DFabric Alliance to Shape the Future of Semiconductor and System Innovations, TSMC Japan 3DIC RD Center Completes Clean Room Construction in AIST Tsukuba Center, Silicon Topology Joins TSMC Design Center Alliance (DCA), TSMC FinFlex, N2 Process Innovations Debut at 2022 North America Technology Symposium, Kura Technologies Partners with TSMC to Build the Future of the Metaverse, TSMC Holds Equipment Engineer Workshop to Strengthen Industry-academia Collaboration. The 16FFC platform has been qualified for automotive environment applications e.g., SPICE and aging models, foundation IP characterization, non-volatile memory, interface IP. They have at least six supercomputer projects contracted to use A100, and each of those will need thousands of chips. Or you can try a more direct approach and ask: Why are other companies yielding at TSMC 28nm and you are not? Were now hearing none of them work; no yield anyway,, this foundry is not yielding at a specific process node, comments posted on the Web by journalists and analysts, who should know better, not only offend me, they also insult TSMC and TSMCs top customers who. The paper is a little ambiguous as to which test chip the yields are referring to, hence my initial concern at only a 5.4% yield. This plot is linear, rather than the logarithmic curve of the first plot. To view blog comments and experience other SemiWiki features you must be a registered member. The company repeated its claim of shipping 1 billion good dies on the node, highlighting that it has enjoyed excellent yields while powering much of the industry with a leading-edge node that beats out both Intel and Samsung. Thanks for that, it made me understand the article even better. All rights reserved. @gavbon86 I haven't had a chance to take a look at it yet. Dr. Simon Wang, Director, IoT Business Development, provided the following update: The 22ULL SRAM is a dual VDD rail design, with separate logic (0.6V, SVT + HVT) and bitcell VDD_min (0.8V) values for optimum standby power. I need to ponder a bit more on the opportunity use M0 as a routing layer TSMC indicated that EDA router support for this feature is still being qualified. The N7 capacity in 2019 will exceed 1M 12 wafers per year. Future US, Inc. Full 7th Floor, 130 West 42nd Street, And this is exactly why I scrolled down to the comments section to write this comment. We have never closed a fab or shut down a process technology.. Founder and CEO of Ampere Computing Renee Jones presented at the event and said the company already has its next server chip being fabbed on the N5 process, so it's clear TSMC has already jumped most of the 5nm design hurdles. In the first phase, Dennard scaling refers to the goal of scaling FEOL linear lithographic dimensions by a factor of s (s < 1) in successive process nodes, achieving an improvement of (1 / s**2) in circuit density, measured as gates / mm**2. He writes news and reviews on CPUs, storage and enterprise hardware. TSMC is also working to define its next node beyond N3 and shared some of the industry advances that could help it move beyond 3nm, but didn't provide any specifics of which technologies it would employ. NY 10036. https://lnkd.in/gdeVKdJm Automotive Platform Intel has changed quite a bit since they tried and failed to go head-to-head with TSMC in the foundry business. In the disclosure, TSMC is stating that their 5nm EUV process affords an overall with a ~1.84x logic density increase, a 15% power gain, or a 30% power reduction. @DrUnicornPhD @anandtech https://t.co/2n7ndI0323, I don't believe I've mentioned this explicitly in public, but I promoted him to Senior CPU Editor last month. Nodes 16FFC and 12FFC both received device engineering improvements: NTOs for these nodes will be accepted in 3Q19. Manufacturing Excellence Therefore, it will take some time before TSMC depreciates the fab and equipment it uses for N5. When you hear about TSMC executives saying "yield rates on the process have improved after a two-quarter period with the defect density dropping from 0.3-0.4 to only 0.1-0.3, it is very true, but only a partially story. As part of any risk production, a foundry produces a number of test chips in order to verify that the process is working expected. Qualcomm Announces Next-generation Snapdragon Mobile Chipset Family. TSMC's Tech Symposium consists of a selection of pre-recorded videos, so we'll have further updates as we work through more of the material. N7 is the baseline FinFET process, whereas N7+ offers improved circuit density with the introduction of EUV lithography for selected FEOL layers. There was a conjecture/joke going around a couple of years ago, suggesting that only 7 customers will be able to afford to pursue 7nm designs, and only 5 customers at 5nm. As of Q1'2019, N7 already accounts for 22% of TSMC's total revenue, and we expect the strong momentum on customer adoption and product tapeouts will continue through 2020 and beyond. Using the calculator, a 300 mm wafer with a 17.92 mm2 die would produce 3252 dies per wafer. Also, it's time that BIOS fl https://t.co/z5nD7GAYMj, @ghost_motley I wouldn't say ASUS are overrated at all, but they do cost more than other brands. Mirroring what we've heard from other industry players, TSMC believes that advanced packaging technologies are the key to further density scaling, and that 3D packaging technologies are the best path forward. Still, the company shows no signs of slowing down its rapid pace of innovation and has plans to begin high volume production of its 3nm tech in 2022, compared to Intel's plans to debut its 7nm in late 2022 or early 2023. Part of what makes 5nm yield slightly better is perhaps down to the increasing use of Extreme UltraViolet (EUV) technology, which reduces the total number of manufacturing steps. If TSMC did SRAM this would be both relevant & large. Thank you for showing us the relevant information that would otherwise have been buried under many layers of marketing statistics. On paper, N7+ appears to be marginally better than N7P. Interesting. At higher levels of IP integration, the choice of the wiring track dimensions for routing and power grid distribution and via insertion has a major impact upon the design-limited yield. For those that have access to IEDM papers, search for, 36.7 5nm CMOS Production Technology Platform featuring full-fledged EUV, and High Mobility Channel FinFETs with Densest 0.021 m2 SRAM Cells for Mobile SoC and High Performance Computing Applications, IEEE IEDM 2019. Marvell claim that TSMC N5 improves power by 40% at iso-performance even, from their work on multiple design ports from N7. Do we see Samsung show its D0 trend? N7+ will enter volume ramp in 2H2019, and is demonstrating comparable D0 defect rates as N7. The size and density of particulate and lithographic defects is continuously monitored, using visual and electrical measurements taken on specific non-design structures. advanced fab facilities, defect densities range between 0.3 and 1.2 defects per square cen-timeter, whereas many of the older bipolar lines operate at defect densities as high as 3 defects per square centimeter. Best Quote of the Day TSMC's 7nm process currently yields just shy of 100 million transistors per square millimeter (mTr/mm2) when using dense libraries, about 96.27 mTr/mm2. For CPU, the plot shows a frequency of 1.5 GHz at 0.7 volts, all the way up to 3.25 GHz at 1.2 volts. The flip side is that the throughput of a single EUV machine (175 wafers per hour per mask) is much slower than a non-EUV machine (300 wafers per hour per mask), however the EUVs speed should be multiplied by 4-5 to get a comparison throughput. In short, it is used to ensure whether the software is released or not. Bottom line: Design teams today must accept a greater responsibility for the product-specific yield. To view blog comments and experience other SemiWiki features you must be a registered member. That's why I did the math in the article as you read. The cost assumptions made by design teams typically focus on random defect-limited yield. TSMC was founded in 1987, and has been holding annual Technology Symposium events since 1994 this was the 25th anniversary (which was highlighted prevalently throughout the Santa Clara Convention Center). Well people have to remember that these Numbers Are pure marketing so 3nm is not even same ballpark with real 3nm so the improvements Are Also smaller . The only fear I see is anti trust action by governments as Apple is the world's largest company and getting larger. The first chips on a new process are often mobile processors, especially high-performance mobile processors that can amortize the high cost of moving into a new process. This process is going to be the next step for any customer currently on the N7 or N7P processes as it shares a number design rules between the two. The fact that yields will be up on 5nm compared to 7 is good news for the industry. TSMC claims the N5 process offers up to 15% more performance (at the same power) or 30% power reduction at the same performance, and a 1.8X logic density gain over the 7nm N7 process. N5 is the next-generation technology after N7 that is optimized upfront for both mobile and HPC applications. Pushing the bandwidth further, TSMC was able to get 130 Gb/s still within tolerances in the eye diagram, but at a 0.96 pJ/bit efficiency. Of specific note were the steps taken to address the demanding reliability requirements of automotive customers. We have already seen 112 Gb/s transceivers on other processes, and TSMC was able to do 112 Gb/s here with a 0.76 pJ/bit energy efficiency. The introduction of N6 also highlights an issue that will become increasingly problematic. 2 0 obj << /Length 2376 /Filter /FlateDecode >> stream One downside to DTCO is that when applied to a given process or design, it means that any first generation of a future process node is technically worse than the holistic best version of the previous generation, or at best, on parity, but a lot more expensive. For a better experience, please enable JavaScript in your browser before proceeding. Defect density is counted per thousand lines of code, also known as KLOC. Wouldn't it be better to say the number of defects per mm squared? Heres how it works. Half nodes have been around for a long time. It really is a whole new world. AVALON 2023: Australian International Airshow and Aerospace & Defence Exposition, 3DIC Physical Verification, Siemens EDA and TSMC, Advances in Physical Verification and Thermal Modeling of 3DICs, Achieving 400W Thermal Envelope for AI Datacenter SoCs, TSMC 2022 Open Innovation Platform Ecosystem Forum Preview, Micron and Memory Slamming on brakes after going off the cliff without skidmarks, Application-Specific Lithography: 5nm Node Gate Patterning, How TSMC Contributed to the Death of 450mm and Upset Intel in the Process, Future Semiconductor Technology Innovations, TSMC 2022 Technology Symposium Review Advanced Packaging Development, TSMC 2022 Technology Symposium Review Process Technology Development. Bath Compared with N7, N5 offers substantial power, performance and date density improvement. The N10/N7 capacity ramp has tripled since 2017, as phases 5 through 7 of Gigafab 15 have come online., We have implemented aggressive statistical process control (measured on control wafer sites) for early detection, stop, and fix of process variations e.g., upward/downward shifts in baseline measures, a variance shift, mismatch among tools. For everything else it will be mild at best. TSMC has developed an approach toward process development and design enablement features focused on four platforms mobile, HPC, IoT, and automotive. N6 offers an opportunity to introduce a kicker without that external IP release constraint. Currently, there are over 20 operators and over 20 OEM devices focused on 5G deployment, including Europe, China, Japan, and Southeast Asia., And, dont overlook the deployment of 5G in applications other than consumer phones, such as wireless factory automation. Relic typically does such an awesome job on those. According to ASML, one EUV layer requires one Twinscan NXE step-and-scan system for every ~45,000 wafer starts per month. What are the process-limited and design-limited yield issues?. Looks like N5 is going to be a wonderful node for TSMC. I find there isn't https://t.co/E1nchpVqII, @wsjudd Happy birthday, that looks amazing btw. The company is also working with carbon nanotube devices. Yield, no topic is more important to the semiconductor ecosystem. Yet, the most important design-limited yield issues dont need EDA tool support they are addressed DURING initial design planning. The levels of support for automated driver assistance and ultimately autonomous driving have been defined by SAE International as Level 1 through Level 5. TSMC. The 256Mb HC/HD SRAM macros and product-like logic test chip have consistently demonstrated healthier defect density than our previous generation. The new 5nm process also implements TSMCs next generation (5th gen) of FinFET technology. Are you sure? Also switching to EUV the "lines" drawn are less fuzzy which will lead to better power and I have to assume higher frequencies at least higher frequencies on average. The stage-based OCV (derating multiplier) cell delay calculation will transition to sign-off using the Liberty Variation Format (LVF). They're currently at 12nm for RTX, where AMD is barely competitive at TSMC's 7nm. For over 10 years, packages have also offered two-dimensional improvements to redistribution layer (RDL) and bump pitch lithography. There's no rumor that TSMC has no capacity for nvidia's chips. The process node N5 incorporates additional EUV lithography, to reduce the mask count for layers that would otherwise require extensive multipatterning. You are using an out of date browser. This means that TSMCs N5 process currently sits around 0.10 to 0.11 defects per square centimeter, and the company expects to go below 0.10 as high volume manufacturing ramps into next quarter. N5 Can you add the i7-4790 to your CPU tests? For the SRAM chip, TSMC is demonstrating that it has both high current (HC) and high density (HD) SRAM cells, at a size of 25000 nm2 and 21000 nm2 respectively. A node advancement brings with it advantages, some of which are also shown in the slide. I find there isn't https://t.co/E1nchpVqII, @wsjudd Happy birthday, that looks amazing btw. RetiredEngineer, a well-known semiconductor blogger, has published a table with a calculation of TSMCs sale price per hypothetical chip by node in 2020. It's not useful for pure technical discussion, but it's critical to the business; overhead costs, sustainability, et al. TSMCs latest N5 (5nm) fabrication process appears to be particularly expensive on per-wafer basis because it is new, but its transistor density makes it particularly good for chips with a high transistor count. RF @ChaoticLife13 @anandtech Swift beatings, sounds ominous and thank you very much! In a nutshell, DTCO is essentially one arm of process optimization that occurs as a result of chip design i.e. Lin indicated. When you purchase through links on our site, we may earn an affiliate commission. You mention, for example, that this chip does not utilize self-repair circuitry, whereas presumably commercial chips would, along with a variety of other mechanisms to deal with yield, from the most crude (design the chip with 26 cores, sell something with 24 cores; or design it with 34 banks of L3 and ship it with the best 32 of those 34 enabled) to redundancy on ever smaller scales. The 16FFC-RF-Enhanced process will be qualified for automotive platforms in 2Q20.. Registration is fast, simple, and absolutely free so please. TSMC also shared details around its 3DFabric technology and provided some clues about what technologies it will use to continue scaling beyond the 3nm node. But the point of my question is why do foundries usually just say a yield number without giving those other details? What used to be 30-40 masks on 28 nm is now going above 70 masks on 14nm/10nm, with reports that some leading edge process technologies are already above 100 masks. I have no clue what NVIDIA is going to do with the extra die space at 5nm other than more RTX cores I guess. Source: TSMC). It may not display this or other websites correctly. Registration is fast, simple, and absolutely free so please. This comes down to the greater definition provided at the silicon level by the EUV technology. TSMC's statements came at its 2021 Online Technology Symposium, which kicked off earlier today. Maria Marced, president of TSMC Europe, repeated what has been said before by herself and other TSMC executives before; that defect density reduction is on track for the 28-nm node and ahead of where TSMC was with 40/45-nm process technology at an equivalent stage in its roll out. Defect density is numerical data that determines the number of defects detected in software or component during a specific development period. The current test chip, with. TSMC says that its 5nm fabrication process has significantly lower defect density when compared to 7nm early in its lifecycle. The technology is currently in risk production, with high volume production scheduled for the first half of 2020. While TSMC may have lied about its density, it is still clear that TSMC N5 is the best node in high-volume production. Get instant access to breaking news, in-depth reviews and helpful tips. TSMC states that this chip does not include self-repair circuitry, which means we dont need to add extra transistors to enable that. Wei, president and co-CEO . TSMC continues to deepen its investments in research and development, with $2.96 billion invested in 2019 alone, and the company is building a new R&D center staffed with 8,000 engineers next to the company headquarters. Only thing up in the air is whether some ampere chips from their gaming line will be produced by samsung instead. Dr. J.K. Wang, SVP, Fab Operations, provided a detailed discussion of the ongoing efforts to reduce DPPM and sustain manufacturing excellence. Secondly, N5 heavily relies on usage of extreme ultraviolet lithography and can use it on up to 14 layers. Or, in other words, infinite scaling. (Indeed, it is easy to foresee product technologies starting to use the metric gates / mm**3 .). It is defined with innovative scaling features to enhance logic, SRAM and analog density simultaneously. For this chip, TSMC has published an average yield of ~80%, with a peak yield per wafer of >90%. Also read: TSMC Technology Symposium Review Part II. Some wafers have yielded defects as low as three per wafer, or .006/cm2. TSMC has benefited from the lessons from manufacturing N5 wafers since the first half of 2020 and applied them to N5A. TSMC is investing significantly in enabling these nodes through DTCO, leveraging significant progress in EUV lithography and the introduction of new materials. For sub-6GHz RF front-end design, TSMC is introducing N40SOI in 2019 the transition from 0.18um SOI to 0.13um SOI to N40SOI will offer devices with vastly improved ft and fmax. The first products built on N5 are expected to be smartphone processors for handsets due later this year. For 10nm they rolled out SuperFIN Technology which is a not so clever name for a half node. TSMC details that N5 currently is progressing with defect densities one quarter ahead of N7, with the new node having better yields at the time of mass production than both their predecessor major . One of the key metrics on how well a semiconductor process is developing is looking at its quantitative chip yield or rather, its defect density. If you remembered, who started to show D0 trend in his tech forum? Does it have a benchmark mode? We have established 2D wafer profile measurement criteria, and in-line monitoring and comparison to an acceptance profile across each wafer., The DDM reduction rate on N7 has been the fastest of any node., For automotive customers, we have implemented unique measures to achieve the demanding DPPM requirements. Get instant access to breaking news, in-depth reviews and helpful tips. N5 provides a 15% performance gain or a 30% power reduction, and up to 80% logic density gain over the preceding N7 technology. "We have begun volume production of 16 FinFET in second quarter," said C.C. Anton Shilov is a Freelance News Writer at Toms Hardware US. The best approach toward improving design-limited yield starts at the design planning stage. TSMC announced the N7 and N7+ process nodes at the symposium two years ago. One could point to AMDs Zen 2 chiplet as more applicable chip, given it comes from a non-EUV process which is more amenable to moving to 5nm EUV, however something like this will come later and will use high performance libraries to not be as dense. From: Cold Fusion, 2020 View all Topics Add to Mendeley About this page New top-level BEOL stack options are available with elevated ultra thick metal for inductors with improved Q. It supports ultra-low leakage devices and ultra-low Vdd designs down to 0.4V. Headlines. It is intel but seems after 14nm delay, they do not show it anymore. Unfortunately, we don't have the re-publishing rights for the full paper. The transition of design IP from N7 to N7+ necessitates re-implementation, to achieve a 1.2X logic gate density improvement. To my recollection, for the first time TSMC also indicated they are tracking D0 specifically for large chips, and reported a comparable reduction learning for large designs as for other N7 products. Silicon Motion SM2268XT DRAM-less NVMe SSD Controller: PCIe 4.0 Speeds on a Budget, Western Digital Launches 22 TB HDD for Consumers in Updated My Book Portfolio, ASRock Industrial's 4X4 BOX 7000/D5 Series Brings Zen 3+ and USB4 40Gbps to UCFF Systems, Western Digital Unveils Dual Actuator Ultrastar DC HS760 20TB HDD, Seagate Confirms 30TB+ HAMR HDDs in Q3, Envisions 50TB Drives in a Few Years, Intel Reports Q4 2022 and FY 2022 Earnings: 2022 Goes Out on a Low Note, SK hynix Intros LPDDR5T Memory: Low Power RAM at up to 9.6Gbps, TSMC's 3nm Journey: Slow Ramp, Huge Investments, Big Future, Micron Launches 9400 NVMe Series: U.3 SSDs for Data Center Workloads, CES 2023: QNAP Brings Hybrid Processors and E1.S SSD Support to the NAS Market, CES 2023: Akasa Introduces Fanless Cases for Wall Street Canyon NUCs, CES 2023: IOGEAR Introduces USB-C Docking Solutions and Matrix KVM, I bet it's a decent board as the Tomahawk series is one of the go to midrange models. By continuing to use the site and/or by logging into your account, you agree to the Sites updated. 3nm is two full process nodes ahead of 5nm and only netting TSMC a 10-15% performance increase? Their 5nm EUV on track for volume next year, and 3nm soon after. The three main types are uLVT, LVT and SVT, which all three have low leakage (LL) variants. To make things simple, we assume the chip is square, we can adjust the defect rate in order to equal a yield of 80%. If the SRAM is 30% of the chip, then the whole chip should be around 17.92 mm2. They are saying 1.271 per sq cm. The process offers either, a 35% speed gain or, a 55% power reduction, as compared with TSMC's existing 28nm HKMG planar process. We anticipate aggressive N7 automotive adoption in 2021.,Dr. Ultimately its only a small drop. The effects of this co-optimization can be dramatic: the equivalent of another process node jump in PPA is not something to be sniffed at, and it also means that it takes time to implement. This collection of technologies enables a myriad of packaging options. The company certainly isn't wasting any time speeding past its competitors one year after breaking ground in 2018, TSMC began moving in over 1,300 fab tools, completing that task in just eight months. The source of the table was not mentioned, but it probably comes from a recent report covering foundry business and makers of semiconductors. Why are other companies yielding at TSMC 28nm and you are not? You are currently viewing SemiWiki as a guest which gives you limited access to the site. TSMC also briefly highlighted ongoing R&D activities in materials research for future nodes e.g., Ge nanowire/nanoslab device channels, 2D semiconductor materials (ZrSe2, MoSe2) see the figure below (Source: TSMC). Three Key Takeaways from the 2022 TSMC Technical Symposium! Using a proprietary technique, TSMC reports tests with defect density of .014/sq. The company is now rolling these technologies under a new "3DFabric" umbrella, which appears to be a new branding scheme for its 3D packaging technologies that tie together chiplets, high bandwidth memory, and specialized IPs into heterogeneous packages. Bryant referenced un-named contacts made with multiple companies waiting for designs to be produced by TSMC on 28-nm processes. But the fact that DTCO is needed just to draw parity means that were getting a further elongation of process node announcements: if it doesnt come with a form of DTCO, its not worth announcing as no-body will want it. One obvious data point that TSMC hasn't disclosed is the exact details on its fin pitch sizes, or contacted poly pitch (cpp), which are often quoted when disclosing risk production of new process nodes. Bryant said that there are 10 designs in manufacture from seven companies. (In his charts, the forecast for L3/L4/L5 adoption is ~0.3% in 2020, and 2.5% in 2025. The test significance level is . Because it is IP-compatible with the N5 node, TSMC's 5nm N4 process offers a straightforward migration with unspecified performance, power, and density enhancements.
