tsmc defect density

You must register or log in to view/post comments. A manufacturing process that has fewer defects per given unit area will produce more known good silicon than one that has more defects, and the goal of any foundry process is to minimize that defect rate over time. So, the next time you hear someone say, that process is not yielding, be sure to stop them and ask: Are you sure? 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. (In his charts, the forecast for L3/L4/L5 adoption is ~0.3% in 2020, and 2.5% in 2025. If Apple was Samsung Foundry's top customer, what will be Samsung's answer? TSMC introduced a new node offering, denoted as N6. In short, it is used to ensure whether the software is released or not. We have never closed a fab or shut down a process technology. (Wow.). 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. Thanks for that, it made me understand the article even better. 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. They are saying 1.271 per sq cm. 23 Comments. TSMC has focused on defect density (D0) reduction for N7. Yields based on simplest structure and yet a small one. For now, head here for more info. This collection of technologies enables a myriad of packaging options. The size and density of particulate and lithographic defects is continuously monitored, using visual and electrical measurements taken on specific non-design structures. N6 strikes me as a continuation of TSMCs introduction of a half node process roadmap, as depicted below. First, some general items that might be of interest: Longevity 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. This means that TSMC's N5 process currently sits around 0.10 to 0.11 defects per square centimeter, and the company. Only thing up in the air is whether some ampere chips from their gaming line will be produced by samsung instead. . Knowing the yield and the die size, we can go to a common online wafer-per-die calculator to extrapolate the defect rate. TSMC N5 from almost 100% utilization to less than 70% over 2 quarters. This comes down to the greater definition provided at the silicon level by the EUV technology. It is intel but seems after 14nm delay, they do not show it anymore. Remember when Intel called FinFETs Trigate? One of the features becoming very apparent this year at IEDM is the use of DTCO. By contrast, the worlds largest contract maker of semiconductors charges around $9,346 per 300mm wafer patterned using its N7 node as well as $3,984 for a 300mm wafer fabbed using its 16nm or 12nm technology. Traditional models for process-limited yield are based upon random defect fails, and have stood the test of time over many process generations. . 3nm is two full process nodes ahead of 5nm and only netting TSMC a 10-15% performance increase? Fabrication design rules were augmented to include recommended, then restricted, and now equation-based specifications to enhance the window of process variation latitude. Definition: Defect density can be defined as the number of confirmed bugs in a software application or module during the period of development, divided by the size of the software. 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. Meanwhile, the foundry sale price per chip also includes design costs, yet this number varies greatly from company to company and from node to node (i.e., design costs of a 610 mm25nmaredifferent for different companies and implementation of a 610 mm2chip varies from node to node due to different design rules and IP), so it should be taken with a grain of salt. TSMC has developed new LSI (Local SI Interconnect) variants of its InFO and CoWoS packaging that merit further coverage in another article. 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. Why? Automotive customers tend to lag consumer adoption by ~2-3 years, to leverage DPPM learning although that interval is diminishing. Currently, the manufacturer is nothing more than rumors. Another dumb idea that they probably spent millions of dollars on. For 10nm they rolled out SuperFIN Technology which is a not so clever name for a half node. 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. As a result, addressing design-limited yield factors is now a critical pre-tapeout requirement. Headlines. The transition of design IP from N7 to N7+ necessitates re-implementation, to achieve a 1.2X logic gate density improvement. The company also said its 3nm N3 node would begin risk production in 2021 and hit high volume manufacturing (HVM) in the second half of 2022. TSMC. I have no clue what NVIDIA is going to do with the extra die space at 5nm other than more RTX cores I guess. There are several factors that make TSMCs N5 node so expensive to use today. The high-volume ramp of 16nm FinFET tech begins this quarter, on-track with expectations. N10 to N7 to N7+ to N6 to N5 to N4 to N3. This is pretty good for a process in the middle of risk production. Equipment is reused and yield is industry leading. You are currently viewing SemiWiki as a guest which gives you limited access to the site. TSMC has more than 15 years of experience with nanosheet technologies and has demonstrated that it can yield working 32Mb nanosheet SRAM devices that operate at 0.46V. BA1 1UA. TSMC also covered its N12E process, which is designed specifically for low-power devices, like IoT, mobile, and edge devices, while improving density. 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. Consider the opportunities for manufacturing flexibility in a wire-free environment, enabled by 5G., for early detection, stop, and fix of process variations e.g., upward/downward shifts in baseline measures, a variance shift, mismatch among tools. L2+ TSMC is investing significantly in enabling these nodes through DTCO, leveraging significant progress in EUV lithography and the introduction of new materials. Firstly, TSMC started to produce 5nm chips several months ago and the fab as well as equipment it uses have not depreciated yet. Nvidia IS on TSMC, but they're obviously using all their allocation to produce A100s. This plot is linear, rather than the logarithmic curve of the first plot. Sometimes I preempt our readers questions ;). According to TSMC, its N5 has a lower defect density than N7 at the same time of its lifespan, so chip designers can expect that eventually N5-based chips will yield better than N7-based ICs in general. Weve updated our terms. . The company has already taped out over 140 designs, with plans for 200 devices by the end of the year. There will be ~30-40 MCUs per vehicle. 2023. It's not useful for pure technical discussion, but it's critical to the business; overhead costs, sustainability, et al. Those are screen grabs that were not supposed to be published. Do we see Samsung show its D0 trend? That seems a bit paltry, doesn't it? TSMC also has its enhanced N5P node in development for high performance applications, with plans to ramp in 2021. This means that chips built on 5nm should be ready in the latter half of 2020. That's why I did the math in the article as you read. Because its a commercial drag, nothing more. For 5nm, TSMC is disclosing two such chips: one built on SRAM, and other combing SRAM, logic, and IO. Weve updated our terms. The latter is something to expect given the fact that N5 replaces DUV multi-patterning with EUV single patterning. The first products built on N5 are expected to be smartphone processors for handsets due later this year. 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. 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. Inverse Lithography Technology A Status Update from TSMC, 2019 TSMC Technology Symposium Review Part I, 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, N7 is in production, with over 100 new tapeouts (NTOs) expected in 2019. 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. TSMC. (link). TSMC has also identified several non-silicon materials suitable for 2D that could scale channel thickness below 1nm. He indicated, Our commitment to legacy processes is unwavering. The levels of support for automated driver assistance and ultimately autonomous driving have been defined by SAE International as Level 1 through Level 5. Compare toi 7nm process at 0.09 per sq cm. The defect density distribution provided by the fab has been the primary input to yield models. In reality these still Are about 40 to 54 nm in reality correct me if I am wrong , isnt true 3nm impossible to reach ? https://lnkd.in/gdeVKdJm 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. TSMCs first 5nm process, called N5, is currently in high volume production. Description: Defect density can be calculated as the defect count/size of the release. @ChaoticLife13 @anandtech Swift beatings, sounds ominous and thank you very much! On paper, N7+ appears to be marginally better than N7P. Marvell claim that TSMC N5 improves power by 40% at iso-performance even, from their work on multiple design ports from N7. As far as foundry sale price per patterned 300-mm wafer is concerned, the model takes into account such things as CapEx, energy use, depreciation, assembly, test and packaging costs, foundry operating margins, and some other factors. Again, taking the die as square, a defect rate of 1.271 per cm2 would afford a yield of 32.0%. 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. N7 is the baseline FinFET process, whereas N7+ offers improved circuit density with the introduction of EUV lithography for selected FEOL layers. Subscribe to the JEDEC Dictionary RSS Feed to receive updates when new dictionary entries are added.. 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. Or, in other words, infinite scaling. (Indeed, it is easy to foresee product technologies starting to use the metric gates / mm**3 .). 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. TSMC states that this chip does not include self-repair circuitry, which means we dont need to add extra transistors to enable that. If TSMC did SRAM this would be both relevant & large. This is why I still come to Anandtech. 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. Xilinx Reaches Industry Milestone with Record-Fast 28nm Product Rollout @gustavokov @IanCutress It's not just you. @ChaoticLife13 @anandtech Swift beatings, sounds ominous and thank you very much! 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. 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. Interesting. I've heard rumors that Ampere is going to 7nm, which is going to keep them ahead of AMD probably even at 5nm. Based on a die of what size? Bryant referenced un-named contacts made with multiple companies waiting for designs to be produced by TSMC on 28-nm processes. This process maximizes die cost scaling by simultaneously incorporating optical shrink and process simplification. Defect density is numerical data that determines the number of defects detected in software or component during a specific development period. N5P offers 5% more performance (as iso-power) or a 10% reduction in power (at iso-performance) over N5. Clearly, the momentum behind N7/N6 and N5 across mobile communication, HPC, and automotive (L1-L5) applications dispels that idea. 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. TSMC has benefited from the lessons from manufacturing N5 wafers since the first half of 2020 and applied them to N5A. But what is the projection for the future? TSMC are the current leaders in silicon device production and this should help keep them in that spot, and also benefit those who use them to manufacture their chips. In a nutshell, DTCO is essentially one arm of process optimization that occurs as a result of chip design i.e. The migration of a design integrating external IP is dependent upon the engineering and financial resources of the IP provider to develop, release (on a testsite shuttle), characterize, and qualify the IP on a new node on a suitable schedule. I double checked, they are the ones presented. Over the past couple of decades, he has covered everything from CPUs and GPUs to supercomputers and from modern process technologies and latest fab tools to high-tech industry trends. Visit our corporate site (opens in new tab). The process offers either, a 35% speed gain or, a 55% power reduction, as compared with TSMC's existing 28nm HKMG planar process. 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. TSMC illustrated a dichotomy in N7 die sizes mobile customers at <100 mm**2, and HPC customers at >300 mm**2. New York, Remember, TSMC is doing half steps and killing the learning curve. Are you sure? This means that current yields of 5nm chips are higher than yields of . This means that the new 5nm process should be around 177.14 mTr/mm2. As part of any risk production, a foundry produces a number of test chips in order to verify that the process is working expected. Dr. Cheng-Ming Lin, Director, Automotive Business Development, describes the unique requirements of TSMCs automotive customers, specifically with regards to continuity of supply over a much longer product lifetime. Or you can try a more direct approach and ask: Why are other companies yielding at TSMC 28nm and you are not? Secondly, N5 heavily relies on usage of extreme ultraviolet lithography and can use it on up to 14 layers. 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. 2 0 obj << /Length 2376 /Filter /FlateDecode >> stream NY 10036. N7+ is said to deliver 10% higher performance at iso-power or, alternatively, up to 15% lower power at iso-performance. Manufacturing Excellence The process node N5 incorporates additional EUV lithography, to reduce the mask count for layers that would otherwise require extensive multipatterning. TSMC listed nanosheets and nanowires among the advances, along with new materials, like high mobility channels, 2D transistors, and carbon nanotubes as candidates that it is already researching. Of course, a test chip yielding could mean anything. One of the key elements in future chips is the ability to support multiple communication technologies, and in the test chip TSMC also included a transceiver designed to enable high-speed PAM-4. Yield is a metric used in MFG that transfers a meaningful information related to the business aspects of the technology. Figure 3-13 shows how the industry has decreased defect density as die sizes have increased. We will support product-specific upper spec limit and lower spec limit criteria. TSMC's 26th Technology Symposium kicked off today with details around its progress with its 7nm N7 process, 5nm N5, N4, and 3nm N3 nodes. Three Key Takeaways from the 2022 TSMC Technical Symposium! RF The N5 process thus ensures 15% higher power or 30% lower consumption and 1.8 times the density of transistors compared to N7. (with low VDD standard cells at SVT, 0.5V VDD). Perhaps in recognition of the difficulties in achieving L3 through L5, a new L2+ level has been proposed (albeit outside of SAE), with additional camera and decision support features. Bryant referenced un-named contacts made with multiple companies waiting for designs to be produced by TSMC on 28-nm processes. England and Wales company registration number 2008885. At N5, the chip will not only be relatively small (at 610mm2tobe more precise), but it will also run 15% faster at a given power or consume 30% less power at a given frequency when compared to N7. The N5 node is going to do wonders for AMD. 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/N7+ If youre only here to read the key numbers, then here they are. 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. 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. For 5nm, TSMC says it's ramping N5 production in Fab 18, its fourth Gigafab and first 5nm fab. Highlights of Dr. Wangs presentation included: Since the introduction of the N16 node, we have accelerated the manufacturing capacity ramp for each node in the first 6 months at an ever-increasing rate. For over 10 years, packages have also offered two-dimensional improvements to redistribution layer (RDL) and bump pitch lithography. Given TSMCs volumes, it needs loads of such scanners for its N5 technology. These were the nodes that Pascal and Turing were on respectively, yet NVIDIA wanted to add around 60% more transistors between the GP102 (1080 Ti) and TU102 (2080 Ti). 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. An L2+ car would typically integrate 6 cameras, 4 short-range radar systems, and 1 long-range radar unit, requiring in excess of 50GFLOPS graphics processing and >10K DMIPS navigational processing throughput.. Same with Samsung and Globalfoundries. Paul Alcorn is the Deputy Managing Editor for Tom's Hardware US. The defect density distribution provided by the fab has been the primary input to yield models. TSMC invited Jim Thompson, CTO, Qualcomm, to provide his perspective on N7 a very enlightening presentation: N6 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. Source: TSMC). It is defined with innovative scaling features to enhance logic, SRAM and analog density simultaneously. The TSMC RF CMOS offerings will be used for SRR, LRR, and Lidar. We're hoping TSMC publishes this data in due course. 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). 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%. Three Key Takeaways from the 2022 TSMC Technical Symposium! %PDF-1.2 % The cost assumptions made by design teams typically focus on random defect-limited yield. 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. Registration is fast, simple, and absolutely free so please, by Tom Dillinger on 04-30-2019 at 7:00 am, The first Silicon Valley symposium had less than 100 attendees now, the attendance exceeds 2000., Our commitment to legacy processes is unwavering. Therefore, it will take some time before TSMC depreciates the fab and equipment it uses for N5. I expect medical to be Apple's next mega market, which they have been working on for many years. Why are other companies yielding at TSMC 28nm and you are not? Those two graphs look inconsistent for N5 vs. N7. The rumor is based on them having a contract with samsung in 2019. Each EUV tool is believed to cost about $120 million and these scanners are rather expensive to run, too. 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. Interesting things to come, especially with the tremendous sums and increasing on medical world wide. @gavbon86 I haven't had a chance to take a look at it yet. And, there are SPC criteria for a maverick lot, which will be scrapped. He writes news and reviews on CPUs, storage and enterprise hardware. 10nm Technology TSMC's 10nm Fin Field-Effect Transistor (FinFET) process provides the most competitive combination of performance, power, area. Yield, no topic is more important to the semiconductor ecosystem. Copyright 2023 SemiWiki.com. Half nodes have been around for a long time. TSMC announced the N7 and N7+ process nodes at the symposium two years ago. Fab 18 began volume production of N5 in the second quarter of 2020 and is designed to process approximately one million 12-inch wafers per year. To make things simple, we assume the chip is square, we can adjust the defect rate in order to equal a yield of 80%. By continuing to use the site and/or by logging into your account, you agree to the Sites updated. Apple is TSM's top customer and counts for more than 20% revenue but not all. 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 . For over 10 years, packages have also offered two-dimensional improvements to redistribution layer (RDL) and bump pitch lithography. You are currently viewing SemiWiki as a guest which gives you limited access to the site. I find there isn't https://t.co/E1nchpVqII, @wsjudd Happy birthday, that looks amazing btw. Bath These terms are often used synonymously, although in the same sense that there are different yield responsibilities, these terms are also very different. Defect Density The defect density and mechanical condition of the bulk material which permits the Pd lattice to withstand and contains high bulk deuterium activities when D atoms equilibrate to produce extreme pressures of D2 gas inside closed incipient voids within the metal. Best Quip of the Day 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. Relic typically does such an awesome job on those. 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. There are parametric yield loss factors as well, which relate to the electrical characteristics of devices and parasitics. TSM has truly reached critical mass in several respects and I expect them to further outpace the competition with Apple's finances and marketing muscle which is immense and growing with no sign of a slowdown. The test significance level is . Intel, TSMC, and to a certain extent Samsung, have to apply some form of DTCO to every new process (and every process variant) for specific products. on the Business environment in China. Usually it was a process shrink done without celebration to save money for the high volume parts. The N4 enhancement to the 5nm family further improves performance, power efficiency and transistor density along with the reduction of mask layers and close compatibility in . Registration is fast, simple, and absolutely free so please. S is equal to zero. The source of the table was not mentioned, but it probably comes from a recent report covering foundry business and makers of semiconductors. 2023 White PaPer. @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. 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. I would say the answer form TSM's top executive is not proper but it is true. The first Silicon Valley symposium had less than 100 attendees now, the attendance exceeds 2000., according to Dave Keller, President and CEO of TSMC North America.

And this is exactly why I scrolled down to the comments section to write this comment. Can you add the i7-4790 to your CPU tests? 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. The three main types are uLVT, LVT and SVT, which all three have low leakage (LL) variants. For higher-end applications, 16FFC-RF is appropriate, followed by N7-RF in 2H20. Using the calculator, a 300 mm wafer with a 17.92 mm2 die would produce 3252 dies per wafer. JavaScript is disabled. TSMC's 7nm Fin Field-Effect Transistor (FinFET) process technology provides the industry's most competitive logic density. 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 current test chip, with 256 Mb of SRAM and some logic, is yielding 80% on average and 90%+ in peak, although scaled back to the size of a modern mobile chip, the yield is a lot lower. 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). TSMC says that its 5nm fabrication process has significantly lower defect density when compared to 7nm early in its lifecycle.
