| TSMC Kicks Off Volume Production of 7nm Chips TSMC last week announced that it had started high volume production (HVM) of chips using their first-gen 7 nm (CLN7FF) process technology. The contract maker of semiconductors says it has over a dozen of customers with tens of designs eager to use the technology to make their integrated circuits. The 7 nm node is a big deal for the foundry industry in general and TSMC in particular. When compared to the CLN16FF+ technology (TSMC’s most widely used FinFET process technology) the CLN7FF will enable chip designers to shrink their die sizes by 70% (at the same transistor count), drop power consumption by 60%, or increase frequency by 30% (at the same complexity). So far, TSMC has taped out 18 customer products using the CLN7FF technology, more than 50 CLN7FF products will be taped out by the end of 2018. Unlike TSMC’s CLN10FF, which is used by a limited number of customers for a limited number of mobile SoCs, the CLN7FF is expected to be used to build CPUs, GPUs, FPGAs, neural network processors, cryptocurrency mining accelerators, mobile SoCs and so on. This is important because demand for smartphones is slowing down and TSMC needs other customers to offset lower orders for mobile SoCs. “So far, we have already favored out more than 18 customer products with good yield [and] performance,” said C. C. Wei, a Co-CEO and President of TSMC, during a conference call with financial analysts. “More than 50 products tape-outs has been planned by end of this year from applications across mobile, server CPU, network processor, gaming, GPU, PGA, cryptocurrency, automotive and AI. Our 7nm is already in volume production.” TSMC’s CLN7FF process technology will rely on deep ultraviolet (DUV) lithography with argon fluoride (ArF) excimer lasers operating on a 193 nm wavelength. As a result, the world’s largest contract maker of semiconductors will be able to use existing manufacturing tools to make 7 nm chips. Meanwhile, to keep using DUV lithography the company and its customers have to use multipatterning (triple and quadruple patterning), which increases design and production costs as well as product cycles. https://www.anandtech.com/show/12677...n-of-7nm-chips |
