According to Scott, overall, the two processes are similar in density with TSMC leading in the ramp-up and likely yield and I agree, absolutely. The company is optimistic that its risk trial production yield in the second half of 2023 can reach 90%. A 7nm data-center processor is now expected to arrive the first half of 2023 rather than in 2022 as expected. TSMC, one of the biggest silicon manufacturers in the world, ... Yup that make producing Big Navi chip at 500mm2 7nm at 80% yield rate cost just as much as 750mm2 12nm chip at 50% yield rate. As of now, its 5nm process is already in mass-production and 3nm will enter in 2022. It also has the steepest yield learning curve, d0 coming down faster than in previous nodes. Node names are basically marketing nowadays, samsung's 5LPE ("5nm") is worse than TSMC's 7nm. Intel's 7nm process node is six months behind schedule, and the yield is a year behind. A new report suggests that Nvidia might move the production of Ampere GPUs from Samsung’s 8nm to TSMC’s 7nm process node. 7nm EUV stochastic failure probability. The 7nm node is just the beginning of TSMC's plans, though. I suspect that when 7nm failed to deliver in Samsung, the shift to 8nm was open but Nvidia tried to claw back into TSMC but they said not on your nelly on that timeline. The volume ramp that TSMC executed for N7 was the fastest ever to meet time to market, faster than 10nm and 16nm. TSMC 2nm process makes a significant breakthrough. The report claims mass production of TSMC's 5 nm chips will begin in the first quarter of next year at the earliest. TSMC begins 7nm+ mass production, prepares for 6nm trials in Q1 2020. In addition to AMD, other clients like Huida, Supermicro, and MediaTek have also placed additional 7nm orders, allowing the Taiwanese Foundry to expand its 7nm … 7nm features are expected to approach ~20 nm width. The primary driver is the yield of Intel's 7nm process, ... You know this is why TSMC did the initial 7nm where only some up front processes were 7nm rest was 12-14nm. There is no two ways about it, TSMC's 7nm is very much superior to Samsung's 8nm which is a tweaked 10nm. The primary driver is the yield of Intel's 7nm process, which based on recent data, is now trending approximately twelve months behind the company's internal target. Samsung and TSMC are struggling to attract customers who want to have 5nm process chips manufactured. I won't be the judge whether this guy knows his beef, but there are some yield benchmarks to the dismay of fanbots of a very vocal community. The probability of EUV stochastic failure is measurably high for the commonly applied dose of 30 mJ/cm 2 . In the case of TSMC, we know that their customers pay almost twice as much for chips manufactured in this process compared to 7nm from the same company. 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. TSMC Talks 7nm, 5nm, Yield, and Next-Gen 5G and HPC Packaging (wikichip.org) 176 points by rbanffy 6 months ago | hide | past | web | favorite | 77 comments sanxiyn 6 months ago AMD has placed 5nm GPU orders for its future RDNA 3 graphics cards, essentially upending a crisis at TSMC. With its 7nm family of technologies in volume production since 2018, TSMC possesses industry-leading yield learning and quality assurance experience to both deliver on the increasing demand for leading-edge processes to fulfill high computation needs for automotive applications, and also meet rigorous durability and reliability requirements. Hsinchu, Taiwan R.O.C., September 26, 2019 - Arm and TSMC, the High-Performance Computing (HPC) industry leaders, today announced an industry-first 7nm silicon-proven chiplet system based on multiple Arm® cores and leveraging TSMC’s Chip-on-Wafer-on-Substrate (CoWoS®) advanced packaging solution. Nvidia is reportedly partnering with TSMC for 7nm Ampere production next year A smart way to avoid Samsung's yield troubles ... and could signify the long-awaited arrival of 7nm Ampere cards. They found that TSMC’s 5nm node requires exceptionally expensive wafers that aren’t cheaper on a per-chip basis than 7nm chips. -- Digitimes (online translated) -- TSMC 7nm chips is a major supporting force for 5G products. With AMD's recent growth and the increased popularity of Apple's latest iPhones, TSMC's 7nm capacity is reportedly at its limits, which is great news for TSMC if it can steadily increase its productivity. TSMC has already increased its quarterly spending to help prepare for the company's high demands for both 7nm and 5nm silicon. Share this post via: Categories Foundries , Samsung Foundry , TSMC Tags 7nm , euv , ic knowledge , samsung 7lpe , scotten jones , smasung 7nm , tsmc , tsmc … However, they still believe that 5nm chips are a popular purchase. Apple and AMD have a very large chunk of their capacity booked up. TSMC has been formally recognized by the IEEE with the 2021 IEEE Corporate Innovation Award. Intel CEO Bob Swan has said that the debut of the company's own 7nm manufacturing process has been delayed by a further 6 months due to yield issues. With its 7nm family of technologies in volume production since 2018, TSMC says it offers industry-leading yield learning and quality assurance experience to fulfill high computation needs for automotive applications, while also meeting durability and reliability requirements. The issue isn't density it's power efficiency; Ampere was probably designed with TSMC's 7nm process in mind and its efficiency. We also know that AMD has been shipping 7nm silicon out of TSMC since mid-2019, implying that the node should be pretty mature by now, even for high-power desktop chips and GPUs.
