Looks like N5 is going to be a wonderful node for TSMC. Manufacturing Excellence 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. As it stands, the defect rate of a new process node is often compared to what the defect rate was for the previous node at the same time in development. Now half nodes are a full on process node celebration. Today at the IEEE IEDM Conference, TSMC is presenting a paper giving an overview of the initial results it has achieved on its 5nm process. 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. There are parametric yield loss factors as well, which relate to the electrical characteristics of devices and parasitics. 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. 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. 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. Qualcomm Announces Next-generation Snapdragon Mobile Chipset Family. First, some general items that might be of interest: Longevity Mii, Senior Vice President of Research and Development / Technology Development , highlighted three eras of process technology development, as depicted in the figure below from his presentation. You are currently viewing SemiWiki as a guest which gives you limited access to the site. TSMC illustrated a dichotomy in N7 die sizes - mobile customers at <100 mm**2, and HPC customers at >300 mm**2. 2023 White PaPer. Then eLVT sits on the top, with quite a big jump from uLVT to eLVT. 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. Future US, Inc. Full 7th Floor, 130 West 42nd Street, TSMC is actively promoting its HD SRAM cells as the smallest ever reported. There will be ~30-40 MCUs per vehicle. 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. 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. 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. TSMC also has its enhanced N5P node in development for high performance applications, with plans to ramp in 2021. The company is also working with carbon nanotube devices. TSMC also introduced a more cost-effective 16nm FinFET Compact Technology (16FFC),which entered production in the second quarter of 2016. https://www.anandtech.com/show/16028/better-yield-on-5nm-than-7nm-tsmc-update-on-defect-rates-for-n5. So, a 17.92 mm2 die isnt particularly indicative of a modern chip on a high performance process. Qualcomm Announces Next-generation Snapdragon Mobile Chipset Family For example, the Kirin 990 5G built on 7nm EUV is over 100 mm2, closer to 110 mm2. Bottom line: Design teams today must accept a greater responsibility for the product-specific yield. If we're doing calculations, also of interest is the extent to which design efforts to boost yield work. Compared with N7, N5 offers substantial power, performance and date density improvement. @gavbon86 I haven't had a chance to take a look at it yet. 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. 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. The first phase of that project will be complete in 2021. 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. You are using an out of date browser. 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. ), (Note initially when I read it the first time, I saw this only in the context of the 5.376 mm2 SRAM-only die.

Interesting. I expect medical to be Apple's next mega market, which they have been working on for many years. L2+ In order to determine a suitable area to examine for defects, you first need . Why? as N7, N7 designs could simply re-tapeout (RTO) to N6 for improved yield with EUV mask lithography, or, N7 designs could submit a new tapeout (NTO) by re-implementing logic blocks using an N6 standard cell library (H240) that leverages a common PODE (CPODE) device between cells for an ~18% improvement in logic block density, risk production in 1Q20 (a 13 level metal interconnect stack was illustrated), although design rule compatible with N7, N6 also introduces a very unique feature M0 routing, risk production started in March19, high volume ramp in 2Q20 at the recently completed Gigafab 18 in Tainan (phase 1 equipment installation completed in March19), intended to support both mobile and high-performance computing platform customers; high-performance applications will want to utilize a new extra low Vt(ELVT) device, an N5P (plus) offering is planned, with a +7% performance boost at constant power, or ~15% power reduction at constant perf over N5 (one year after N5), N5 will utilize a high-mobility (Ge) device channel, super high-density MIM offering (N5), with 2X ff/um**2 and 2X insertion density, metal Reactive Ion Etching (RIE), replacing Cu damascene for metal pitch < 30um, a graphene cap to reduce Cu interconnect resistivity, 16FFC+ : +10% perf @ constant power, +20% power @ constant perf over 16FFC, 12FFC+ : +7% perf @ constant power, +15% power @ constant perf over 12FFC, introduction of new devices for the 22ULL node: EHVT device, ultra-low leakage SRAM. Part of the IEDM paper describes seven different types of transistor for customers to use. It may not display this or other websites correctly. Growth in semi content 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. Relic typically does such an awesome job on those. TSMC. 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. 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. N6 offers an opportunity to introduce a kicker without that external IP release constraint. 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 introduced a new node offering, denoted as N6. Based on a die of what size? Copyright 2023 SemiWiki.com. The fact that yields will be up on 5nm compared to 7 is good news for the industry. They have at least six supercomputer projects contracted to use A100, and each of those will need thousands of chips. Bryant said that there are 10 designs in manufacture from seven companies. It is defined with innovative scaling features to enhance logic, SRAM and analog density simultaneously. This plot is linear, rather than the logarithmic curve of the first plot. I would say the answer form TSM's top executive is not proper but it is true. What do they mean when they say yield is 80%? 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. Registration is fast, simple, and absolutely free so please. This means that TSMC's N5 process currently sits around 0.10 to 0.11 defects per square centimeter, and the company. In short, it is used to ensure whether the software is released or not. 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. Xilinx Reaches Industry Milestone with Record-Fast 28nm Product Rollout There are several factors that make TSMCs N5 node so expensive to use today. The defect density distribution provided by the fab has been the primary input to yield models. 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. Windows 11 Update Brings New Search Box, But AI Integration is Hype, U.S. Govt Outlines Requirements for CHIPS Act Subsidies, Nvidia's 531.18 Driver Adds RTX Video Super Resolution Support, Gigabyte Aorus 15X Review: Raptor Lake and RTX 4070 Impress, AMD Ryzen 9 7950X3D and 7900X3D: Where to Buy. The size and density of particulate and lithographic defects is continuously monitored, using visual and electrical measurements taken on specific non-design structures. Headlines. A successful chip could just turn on, and the defect rate doesnt take into account how well the process can drive power and frequency. 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 TSMC at least, certain companies may benefit from exclusive rights to certain DTCO improvements, to help those companies get additional performance benefits. Does it have a benchmark mode? The latter is something to expect given the fact that N5 replaces DUV multi-patterning with EUV single patterning. TSMC's industry-leading 5 nanometer (nm) N5 technology entered volume production this year and defect density reduction is proceeding faster than the previous generation as capacity continues to ramp. Yield, no topic is more important to the semiconductor ecosystem. Unfortunately, we don't have the re-publishing rights for the full paper. It is then divided by the size of the software. If we assume around 60 masks for the 16FFC process, the 10FF process is around 80-85 masks, and 7FF is more 90-95. 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. 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. Using the calculator, a 300 mm wafer with a 17.92 mm2 die would produce 3252 dies per wafer. So, the next time you hear someone say, that process is not yielding, be sure to stop them and ask: Are you sure? Marvell claim that TSMC N5 improves power by 40% at iso-performance even, from their work on multiple design ports from N7. TSMC's R&D researchers resolved these issues by developing a proprietary defect-reduction technique that, on initial tests, produced less than seven immersion-induced defects on many 12-inch wafers, a defect density of .014/cm2. As part of the disclosure, TSMC also gave some shmoo plots of voltage against frequency for their example test chip. 6nm. The test significance level is . Intel calls their half nodes 14+, 14++, and 14+++. One thing to keep in mind with such a comparison between nodes is that while it is based on data from TSMC as well as the semiconductor industry in general, the actual numbers have never been confirmed by the Taiwanese giant, so they may not be a 100% accurate. We're hoping TSMC publishes this data in due course. This collection of technologies enables a myriad of packaging options. 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. 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. Description: Defect density can be calculated as the defect count/size of the release. 2 0 obj << /Length 2376 /Filter /FlateDecode >> stream N5 provides a 15% performance gain or a 30% power reduction, and up to 80% logic density gain over the preceding N7 technology. 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. (link). With the multi-die, 3D vertical stacking package technology were describing today specifically, TSMCs SoIC offering we are providing vast improvements in circuit density. 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 has benefited from the lessons from manufacturing N5 wafers since the first half of 2020 and applied them to N5A. Unfortunately TSMC doesnt disclose what they use as an example CPU/GPU, although the CPU part is usually expected to be an Arm core (although it might only be a single core on a chip this size). Like you said Ian I'm sure removing quad patterning helped yields. Doing the math, that would have afforded a defect rate of 4.26, or a 100mm2 yield of 5.40%. The best approach toward improving design-limited yield starts at the design planning stage. 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. ), The adoption rate for the digital dashboard cockpit visualization system will also increase, driving further semiconductor growth 0.2% in 2018 to 11% in 2025.. I've heard rumors that Ampere is going to 7nm, which is going to keep them ahead of AMD probably even at 5nm. To make things simple, we assume the chip is square, we can adjust the defect rate in order to equal a yield of 80%. Anton Shilov is a Freelance News Writer at Toms Hardware US. At 16/12nm node the same processor will be considerably larger and will cost $331 to manufacture. 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. 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. 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. From: Cold Fusion, 2020 View all Topics Add to Mendeley About this page The 256Mb HC/HD SRAM macros and product-like logic test chip have consistently demonstrated healthier defect density than our previous generation. Future Publishing Limited Quay House, The Ambury, Of course, a test chip yielding could mean anything. Lin indicated. And this is exactly why I scrolled down to the comments section to write this comment. Those two graphs look inconsistent for N5 vs. N7. England and Wales company registration number 2008885. For higher-end applications, 16FFC-RF is appropriate, followed by N7-RF in 2H20. That seems a bit paltry, doesn't it? We have established 2D wafer profile measurement criteria, and in-line monitoring and comparison to an acceptance profile across each wafer., Automotive systems will require both advanced logic technologies for ADAS, such as N16FFC, and advanced RF technologies for V2X communications. Automotive customers tend to lag consumer adoption by ~2-3 years, to leverage DPPM learning although that interval is diminishing. We have never closed a fab or shut down a process technology.. The rumor is based on them having a contract with samsung in 2019. Part 2 of this article will review the advanced packaging technologies presented at the TSMC Technology Symposium. resulting in world-class D0 (Defect Density) and DPPM (Defective Parts Per Million) out-of-the gate for automotive - improving both intrinsic and extrinsic quality. Yet, the most important design-limited yield issues dont need EDA tool support they are addressed DURING initial design planning. With the multi-die, 3D vertical stacking package technology were describing today specifically, TSMCs SoIC offering we are providing vast improvements in circuit density. Dr. J.K. Wang, SVP, Fab Operations, provided a detailed discussion of the ongoing efforts to reduce DPPM and sustain manufacturing excellence. Figure 3-13 shows how the industry has decreased defect density as die sizes have increased. Dr. Lin indicated, Automotive systems will require both advanced logic technologies for ADAS, such as N16FFC, and advanced RF technologies for V2X communications.
