So; would I be correct in assuming that mainland China ALSO has to get chips from the Taiwanese; too?
Back around 2002, Mainland China was trying to swing a cross license agreement with Intel.
It nearly happened until someone high up at Intel pointed out the obvious that China was trying to get access at Intel’s patents and advanced technology.
China since then has been trying to invent advanced process technology but so far has been unable.
Beyond 14nm, things get very expensive and much more difficult.
