The 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 ARE yielding. I've heard rumors that Ampere is going to 7nm, which is going to keep them ahead of AMD probably even at 5nm. "We have begun volume production of 16 FinFET in second quarter," said C.C. TSMC announced the N7 and N7+ process nodes at the symposium two years ago. As it stands, the current N5 process from TSMC has a lower defect density than N7 did at the same time in its development cycle. 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. In a nutshell, DTCO is essentially one arm of process optimization that occurs as a result of chip design i.e. Remember, TSMC is doing half steps and killing the learning curve. S is equal to zero. Advanced Materials Engineering The technology is currently in risk production, with high volume production scheduled for the first half of 2020. Yet 5G is moving much faster than 4G did at a comparable point in the rollout schedule, there were only 5 operators and 3 OEM devices supporting 4G, mostly in the US and South Korea. Best Quote of the Day Again, taking the die as square, a defect rate of 1.271 per cm2 would afford a yield of 32.0%. The 16FFC platform has been qualified for automotive environment applications e.g., SPICE and aging models, foundation IP characterization, non-volatile memory, interface IP. If the SRAM is 30% of the chip, then the whole chip should be around 17.92 mm2. 6nm. It often depends on who the lead partner is for the process node. Like you said Ian I'm sure removing quad patterning helped yields. Therefore, it will take some time before TSMC depreciates the fab and equipment it uses for N5. The first products built on N5 are expected to be smartphone processors for handsets due later this year. For 5nm, TSMC is disclosing two such chips: one built on SRAM, and other combing SRAM, logic, and IO. TSMC has already disrupted the pecking order of the semiconductor industry when it brushed aside Intel and Samsung and moved to its industry-leading 7nm node, powering Intel's competitor AMD (among others) to the forefront. I have no clue what NVIDIA is going to do with the extra die space at 5nm other than more RTX cores I guess. You must log in or register to reply here. Part 2 of this article will review the advanced packaging technologies presented at the TSMC Technology Symposium. Ultimately its only a small drop. Bryant referenced un-named contacts made with multiple companies waiting for designs to be produced by TSMC on 28-nm processes. Were now hearing none of them work; no yield anyway, Suffi https://t.co/VrirVdILDv, Now that I've finally had a chance to catch my breath (and catch up on my sleep), a big kudos to @gavbon86 for maki https://t.co/Sddmfr0UtE. A100 is already on 7nm from TSMC, so it's pretty much confirmed TSMC is working with nvidia on ampere. Given the time of the year (and the stres https://t.co/k1hD9NCwGc, @awill_me @anandtech Claimed perf numbers are better than all DRAMless Gen 4 SSD currently in the market, and essen https://t.co/e4QUhCxKm7, @aingsword @anandtech @AsrockComputer The controller supports up to 8 distinct ECC-protected regions [ at least in https://t.co/BZXciTjyGB, Not the typical mini-PC review, thanks to the presence of in-band ECC. Using a proprietary technique, TSMC reports tests with defect density of .014/sq. This is pretty good for a process in the middle of risk production. The process offers either, a 35% speed gain or, a 55% power reduction, as compared with TSMC's existing 28nm HKMG planar process. What are the process-limited and design-limited yield issues?. 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. TSMC was a natural partner since they do not compete with customers and Apple was a VERY big customer when this all started (2014). Compared to their N7 process, N7+ is said to deliver around 1.2x density improvement. All rights reserved. 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. Based on the numbers provided, it costs $238 to make a 610mm2chip using N5 and $233 to produce the same chip using N7. Each step is a potential chance to decrease yield, so by replacing 4 steps of DUV for 1 step of EUV, it eliminates some of that defect rate. 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. A 256 Mbit SRAM cell, at 21000 nm2, gives a die area of 5.376 mm2. It really is a whole new world. @gustavokov @IanCutress It's not just you. And as the TSMC chart shows, for the time being, the defectivity of process N5 is also lower than that of N7, although over time the two processes converge in this respect. The latter is something to expect given the fact that N5 replaces DUV multi-patterning with EUV single patterning. The first phase of that project will be complete in 2021. We have never closed a fab or shut down a process technology. (Wow.). To view blog comments and experience other SemiWiki features you must be a registered member. 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. TSMC has benefited from the lessons from manufacturing N5 wafers since the first half of 2020 and applied them to N5A. @gustavokov @IanCutress It's not just you. Tom's Hardware is part of Future plc, an international media group and leading digital publisher. He indicated, Our commitment to legacy processes is unwavering. 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). The defect density distribution provided by the fab has been the primary input to yield models. N16FFC, and then N7 Given the time of the year (and the stres https://t.co/k1hD9NCwGc, @awill_me @anandtech Claimed perf numbers are better than all DRAMless Gen 4 SSD currently in the market, and essen https://t.co/e4QUhCxKm7, @aingsword @anandtech @AsrockComputer The controller supports up to 8 distinct ECC-protected regions [ at least in https://t.co/BZXciTjyGB, Not the typical mini-PC review, thanks to the presence of in-band ECC. Having spent a number of processes built upon 193nm-based ArF immersion lithography, the mask count for these more and more complex processors has been ballooning. Of course, a test chip yielding could mean anything. 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. The American Chamber of Commerce in South China. 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. With this paper, TSMC is saying that extensive use of EUV for over 10 layers of the design will actually, for the first time, reduce the number of process masks with a new process node. Dr. Mii also confirmed that the defect density for N6 equals N7 and that EUV usage enables TSMC . These parameters are monitored using electrical measurements taken on additional non-design structures during fabrication excursions of these parameters outside process model limits will limit the design from meeting electrical specifications. For example, the Kirin 990 5G built on 7nm EUV is over 100 mm2, closer to 110 mm2. 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. Key highlights include: Making 5G a Reality TSMC shared a few additional details of its 7nm node, which started production in 2018 and has powered many high-performance chips from the likes of AMD, Apple and others. 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. First, some general items that might be of interest: Longevity Significant device R&D is being made to enhance the device ft and fmax for these nodes look for 16FFC-RF-Enhanced in 2020 (fmax > 380GHz) and N7-RF-Enhanced in 2021. After spending a significant part of my career on Design for Manufacturability (DFM) and Design for Yield (DFY), Im seriously offended when semiconductor professionals make false and misleading statements that negatively affects the industry that supports us. In addition to the N5 introduction of a high mobility channel, TSMC highlighted additional materials and device engineering updates: An improved local MIM capacitance will help to address the increased current from the higher gate density. For 5nm, TSMC says it's ramping N5 production in Fab 18, its fourth Gigafab and first 5nm fab. 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. TSMC is actively promoting its HD SRAM cells as the smallest ever reported. Currently, the manufacturer is nothing more than rumors. We have never closed a fab or shut down a process technology.. The TSMC IoT platform is laser-focused on low-cost, low (active) power dissipation, and low leakage (standby) power dissipation. There are new, innovative antenna implementations being pursued in the end, its just math, although complex math for sure., Theres certainly lots of skepticism about the adoption rate of 5G. Interesting things to come, especially with the tremendous sums and increasing on medical world wide. TSMC. I double checked, they are the ones presented. The N7 capacity in 2019 will exceed 1M 12 wafers per year. Another dumb idea that they probably spent millions of dollars on. N7+ is benefitting from improvements in sustained EUV output power (~280W) and uptime (~85%). 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.

Oracle Plans to Speed Up Release of Next-Generation 28nm SPARC T5 Chip, The EDA industry has assisted design teams with addressing process-limited and design-limited yield by offering products for DFM and DFY. 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. We will either scrap an out-of-spec limit wafer, or hold the entire lot for the customers risk assessment. (See the figures below. Apple is TSM's top customer and counts for more than 20% revenue but not all. Those two graphs look inconsistent for N5 vs. N7. Their 5nm EUV on track for volume next year, and 3nm soon after. I find there isn't https://t.co/E1nchpVqII, @wsjudd Happy birthday, that looks amazing btw. The defect density distribution provided by the fab has been the primary input to yield models. This means that TSMC's N5 process currently sits around 0.10 to 0.11 defects per square centimeter, and the company. What are the process-limited and design-limited yield issues?. Best Quip of the Day But the point of my question is why do foundries usually just say a yield number without giving those other details? One could argue that these arent particularly useful: the designs of CPUs and GPUs are very different and a deeply integrated GPU could get a much lower frequency at the same voltage based on its design. TSMC also says the defect density learning curve for N5 is faster than N7, meaning the 5nm process will reach higher yield rates quicker than its predecessor. TSMC is investing significantly in enabling these nodes through DTCO, leveraging significant progress in EUV lithography and the introduction of new materials. TSMC says N6 already has the same defect density as N7. Yet, the most important design-limited yield issues dont need EDA tool support they are addressed DURING initial design planning. on the Business environment in China. Each EUV tool is believed to cost about $120 million and these scanners are rather expensive to run, too. 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. 2 0 obj << /Length 2376 /Filter /FlateDecode >> stream Here is a brief recap of the TSMC advanced process technology status. Bryant said that there are 10 designs in manufacture from seven companies. Yields based on simplest structure and yet a small one. A yield rate of 32.0% for a 100 mm2 chip would even be sufficient for some early adopters wanting to get ahead of the game. There will be ~30-40 MCUs per vehicle. Thankfully in TSMCs 5nm paper at IEDM, the topic of DTCO is directly addressed. @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. Get instant access to breaking news, in-depth reviews and helpful tips. According to ASML, one EUV layer requires one Twinscan NXE step-and-scan system for every ~45,000 wafer starts per month. 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. This plot is linear, rather than the logarithmic curve of the first plot. 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. @ChaoticLife13 @anandtech Swift beatings, sounds ominous and thank you very much! You must register or log in to view/post comments. For a 90 % significance level use = 1.282 and for a 95 % test use = 1.645. is the maximum risk that an acceptable process with a defect density at least as low as "fails" the test. In that chip are 256 mega-bits of SRAM, which means we can calculate a size. Does it have a benchmark mode? TSMC already has a robust portfolio of 3D packaging technologies in its wafer-level 3DIC technologies, like Chip-on-Wafer-on-Substrate (CoWoS), Integrated Fan Out (InFO-R), Chip on Wafer (COW), and Wafer-on-Wafer (WoW). Defect density is numerical data that determines the number of defects detected in software or component during a specific development period. TSMC has also identified several non-silicon materials suitable for 2D that could scale channel thickness below 1nm. TSMC illustrated a dichotomy in N7 die sizes mobile customers at <100 mm**2, and HPC customers at >300 mm**2. N6 offers an opportunity to introduce a kicker without that external IP release constraint. 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. TSMC President and Co-CEO Mark Liu said that 16nm FinFET Plus will have more than 50 tapeouts by the end of 2015 and have 50% less total power over TSMC's 20nm SoC process at the same speed.
