Thanks for the info. Butare you sure they couldn't or cannot ramp up their yield? They bought a lot of TMSC knowledge in the last years.

  It’s the lithography equipment they are using, it isn’t designed for 7nm and the only reason we guess their yields are bad is because lots of people have tried already. TSMC also buys from the same Dutch company, the knowledge/equipment to build commercially viable chips is incredibly distributed: if China took all of TSMC’s factories and people in tact, they would still be unable to do that well because the supply chain is intentionally distributed through multiple US allied countries. China needs to do everything, they will need to produce and master their own lithography and so on.

    Not convinced. E.g. the DUV machines for sure are build to allow flexible multiple patterning. Some progress there may ramp up the yield significantly.
