Probably not. This process is based on DUV so it requires multiple patterning. That didn’t work out great for Intel. No information on yields listed. Also,

Probably not. This process is based on DUV so it requires multiple patterning. That didn’t work out great for Intel. No information on yields listed. Also, DUV equipment is about to become restricted for sale to China, which means they can’t scale the fabs.

Tsmc 7nm doesn't use EUV and is fantastic

  It uses EUV. > 7nm FinFET plus (N7+) technology entered full-scale production in 2019 and delivered customer 7nm products to market in high volume. N7+ technology is the first commercially available extreme ultraviolet EUV-enabled foundry manufacturing process https://www.tsmc.com/english/dedicatedFoundry/technology/logic/l_7nm https://www.tsmc.com/english/dedicatedFoundry/technology/log... It looks like there was a 7nm SRAM process in 2016 that only used DUV, but I'd be surprised if more than, say, 1% of "7nm" mentions over the last few years were intended to refer to the 2016 process rather than the 2019 process.

    That is N7+, normal N7 was without EUV According to Wikipedia: https://en.wikipedia.org/wiki/7_nm_process https://en.wikipedia.org/wiki/7_nm_process , mass production with N7+ which uses EUV was ramping up from 2018 to 2019. It seems that the Apple A12 as well as some Ryzen chips were using the N7 DUV process.

They've been running production for probably more than a year according to the article, so they are likely already done scaling. If they have enough spare capacity from building supercomputers and military chips to make bitcoin ASICs they are probably already at a good scale.

  China already moved in the Semi conductor equipment space years ago during the trump trade war phase. From what i gathered they have secured 28~14nm nodes with almost complete domestic components and materials and non sanctionable component and materials.

    Great, but what about 7nm?
