Lol Kevin zhang oversaw 10nm sram test chip failure at AD for A and B steppings and he is not involved in processOne Taiwanese news program mentioned WJL seldom use computer and he has a habit to use hand written notes. Therefore, I also suspect it is very likely that TSM benefited enormously from from WJL's experience at Intel. Also when Intel's employees joined TSM such as Kevin Zhang, Intel's progress plans/difficulties could be likely leaked out which would allow TSM to devise plans to catch up with Intel.
