Most of those technologies being European, including the most difficult to make components in the system.
Why isn't there an American company doing this? Why isn't an American company making the lasers, mirrors, metrology, vacuum handling tech, etc?
they are licensed to European company yes
reason why US didn't produce most of these component because US gov didn't continue investment so privately owned enterprise take over from there namely ASML
that also reason why US can restrict EUV sales to china
I’d say Japan is a more important source than sources in Europe.
