Anything below 0.5/cm2 is usually a good metric, and weve seen TSMC pull some really interesting numbers, such as 0.09 defects per square centimetre on its N7 process node only three quarters after high volume manufacturing started, as was announced in November at the VLSI Symposium 2019. Yield is a metric used in MFG that transfers a meaningful information related to the business aspects of the technology. TSMC is investing significantly in enabling these nodes through DTCO, leveraging significant progress in EUV lithography and the introduction of new materials. Future US, Inc. Full 7th Floor, 130 West 42nd Street, The company is also working with carbon nanotube devices. Using the calculator, a 300 mm wafer with a 17.92 mm2 die would produce 3252 dies per wafer. They are saying 1.271 per sq cm. Of specific note were the steps taken to address the demanding reliability requirements of automotive customers. The first products built on N5 are expected to be smartphone processors for handsets due later this year. This bodes well for any PAM-4 based technologies, such as PCIe 6.0. 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. If we're doing calculations, also of interest is the extent to which design efforts to boost yield work. The N5 node is going to do wonders for AMD. This means that TSMC's N5 process currently sits around 0.10 to 0.11 defects per square centimeter, and the company. 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. This slide from TSMC was showcased near the start of the event, and a more detailed graph was given later in the day: This plot is linear, rather than the logarithmic curve of the first plot. 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). A successful chip could just turn on, and the defect rate doesnt take into account how well the process can drive power and frequency. Again, taking the die as square, a defect rate of 1.271 per cm2 would afford a yield of 32.0%. So in order to better the previous process technology, at least one generation of DTCO has to be applied to the new node before it can even be made viable, making its roll-out take even longer. Traditional models for process-limited yield are based upon random defect fails, and have stood the test of time over many process generations. What do they mean when they say yield is 80%? To view blog comments and experience other SemiWiki features you must be a registered member. The American Chamber of Commerce in South China. Bottom line: The design teams that collaborate with the fab to better understand how to make design-limited yield tradeoffs in initial planning and near tapeout will have a much smoother path toward realizing product revenue and margins. TSMC illustrated a dichotomy in N7 die sizes mobile customers at <100 mm**2, and HPC customers at >300 mm**2. You can thank Apple for that since they require a new process every year and freeze the process based on TTM versus performance or yield like the other semiconductor manufacture giants. The design team incorporates this input with their measures of the critical area analysis, to estimate the resulting manufacturing yield. 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. N5 provides a 15% performance gain or a 30% power reduction, and up to 80% logic density gain over the preceding N7 technology. For over 10 years, packages have also offered two-dimensional improvements to redistribution layer (RDL) and bump pitch lithography. This means that the new 5nm process should be around 177.14 mTr/mm2. These terms are often used synonymously, although in the same sense that there are different yield responsibilities, these terms are also very different. 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. Bryant referenced un-named contacts made with multiple companies waiting for designs to be produced by TSMC on 28-nm processes. 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. All rights reserved. 23 Comments. For the combined chip, TSMC is stating that the chip consists of 30% SRAM, 60% Logic (CPU/GPU), and 10% IO. Yield, no topic is more important to the semiconductor ecosystem. The best approach toward improving design-limited yield starts at the design planning stage. 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. While ECC may not be a decisive factor in pu https://t.co/1c0ZwLCGFq, @GeorgeBessenyei @anandtech @AsrockComputer We are starting to see NAS vendors adopt -P series SKUs in their units. https://t.co/U1QA3xZIaw, @plugable I would like to see a USBC-TKEY with support for 240W EPR measurement, as well as passthrough support for https://t.co/oyjaSk3yS3. This is very low. Or, in other words, infinite scaling. (Indeed, it is easy to foresee product technologies starting to use the metric gates / mm**3 .).

The only available facts are: "-- J.Huang stated in December, that most of the new GPUs will be manufactured at TSMC, Samsung will only handle the smaller part", TSMC Details 3nm Process Technology: Full Node Scaling for 2H22 Volume Production, TSMC To Build 5nm Fab In Arizona, Set To Come Online In 2024, TSMC & Broadcom Develop 1,700 mm2 CoWoS Interposer: 2X Larger Than Reticles, TSMC Boosts CapEx by $1 Billion, Expects N5 Node to Be Major Success, Early TSMC 5nm Test Chip Yields 80%, HVM Coming in H1 2020, TSMC: 5nm on Track for Q2 2020 HVM, Will Ramp Faster Than 7nm, TSMC: N7+ EUV Process Technology in High Volume, 6nm (N6) Coming Soon. With 5FF and EUV, that number goes back down to the 75-80 number, compared to the 110+ that it might have been without EUV. Because its a commercial drag, nothing more. 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. England and Wales company registration number 2008885. NY 10036. 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. "Only thing up in the air is whether some ampere chips from their gaming line will be produced by samsung instead.". @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. https://www.anandtech.com/show/16028/better-yield-on-5nm-than-7nm-tsmc-update-on-defect-rates-for-n5. https://lnkd.in/gdeVKdJm To view blog comments and experience other SemiWiki features you must be a registered member. It doesnt sound like much, but in this case every little helps: with this element of DTCO, it enables TSMC to quote the 1.84x increase in density for 15+% speed increase/30% power reduction. Although the CAGR for cars from now to 2022 is expected to be only ~1.8%, the CAGR for the semiconductor content will be 6.9%., He continued, The L1/L2 feature adoption will reach ~30%, with additional MCUs applied to safety, connectivity, and EV/hybrid EV features. This is why I still come to Anandtech. The 5nm test chip has an element of DTCO applied, rather than brute-forcing the design rules, which has enabled scaling of the design rules for an overall 40% chip size reduction. For a better experience, please enable JavaScript in your browser before proceeding. Automotive customers tend to lag consumer adoption by ~2-3 years, to leverage DPPM learning although that interval is diminishing. 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. @ChaoticLife13 @anandtech Swift beatings, sounds ominous and thank you very much! We will support product-specific upper spec limit and lower spec limit criteria. The model is based on an imaginary 5nm chip the size of Nvidia's P100 GPU (610 mm2, 90.7 billion transistors at 148.2 MTr/mm2). Bottom line: Design teams today must accept a greater responsibility for the product-specific yield. Dr. Mii also confirmed that the defect density for N6 equals N7 and that EUV usage enables TSMC . Knowing the yield and the die size, we can go to a common online wafer-per-die calculator to extrapolate the defect rate. I found the snapshots of TSM D0 trend from 2020 Technology Symposium from Anandtech report(. The technology is currently in risk production, with high volume production scheduled for the first half of 2020. Relic typically does such an awesome job on those. Or, in other words, Although we anticipate further improvements in power and uptime, these measures are sufficient to proceed to N7+ volume ramp., The D0 improvement ramp has been faster than previous nodes, at a comparable interval after initial production volume ramp., N7 is the enabler for the 5G launch, as demonstrated in our latest Snapdragon 855 release., 5G MIMO with 256 antenna elements supports 64 simultaneous digital streams thats 16 users each receiving 4 data streams to a single phone., Antenna design is indeed extremely crucial for 5G, to overcome path loss and signal blockage. So that overall test chip, at 17.92 mm2, would have been more like 25.1 mm2, with a yield of 73%, rather than 80%. %PDF-1.2 % The transition of design IP from N7 to N7+ necessitates re-implementation, to achieve a 1.2X logic gate density improvement. 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. Fabrication design rules were augmented to include recommended, then restricted, and now equation-based specifications to enhance the window of process variation latitude. Are you sure? Dr. Jay Sun, Director, RF and Analog Business Development provided the following highlights: Summary TSMC also has its enhanced N5P node in development for high performance applications, with plans to ramp in 2021. Same with Samsung and Globalfoundries. Looks like N5 is going to be a wonderful node for TSMC. 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. Yields based on simplest structure and yet a small one. There will be ~30-40 MCUs per vehicle. TSMC also introduced a more cost-effective 16nm FinFET Compact Technology (16FFC),which entered production in the second quarter of 2016. High performance and high transistor density come at a cost. Part of the IEDM paper describes seven different types of transistor for customers to use. Daniel: Is the half node unique for TSM only? Dr. Cheng-Ming Lin, Director, Automotive Business Unit, provided an update on the platform, and the unique characteristics of automotive customers. BA1 1UA. I find there isn't https://t.co/E1nchpVqII, @wsjudd Happy birthday, that looks amazing btw. This will give the customers better throughput when making orders, and the foundry aims to balance that with the cost of improving the manufacturing process. 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. 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 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. Copyright 2023 SemiWiki.com. N7/N7+ The 16FFC platform has been qualified for automotive environment applications e.g., SPICE and aging models, foundation IP characterization, non-volatile memory, interface IP. 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. Paul Alcorn is the Deputy Managing Editor for Tom's Hardware US. N6 strikes me as a continuation of TSMCs introduction of a half node process roadmap, as depicted below. it can be very easy to design a holistic chip and put it onto silicon, but in order to get the best performance/power/area, it needs to be optimized for the process node for the silicon in question. The process node N5 incorporates additional EUV lithography, to reduce the mask count for layers that would otherwise require extensive multipatterning. This is a persistent artefact of the world we now live in. A half-node process is both an engineering-driven and business-driven decision to provide a low-risk design migration path, to offer a cost-reduced option to an existing N7 design as a mid-life kicker.
