I never said anything about ASML stealing technology or ingenuity. The point is that EUV photolithography is an international effort. The machines don't exist at all without about 6 different countries contributing technology and expertise.
ASML has certainly proven itself to be a very capable integrator of many international technologies and processes.
Why isn't there an American company doing this? Why isn't an American company making the lasers, mirrors, metrology, vacuum handling tech, etc?
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
Simultaneously Japan created its own initiative (EUVA), and Gigaphoton didn't rely upon the US initiative at all. And again in an alternate universe -- one where Japan isn't protectionist and Cymer wasn't out of financial runway and desperate -- we'd be talking about how ASML is really Japanese tech, etc.
Has a lot of the history
Yes the OP is completely biased.
Cymer was one of multiple vendors (Gigaphoton, XTREME) providing this sort of light source, and ASML acquired it because it couldn't achieve what they wanted (they needed 100+W and Cymer could only achieve 15W). ASML needed to control and fund the company, and add engineering talent, to achieve what they actually needed.
Oh and ASML bought Cymer because Gigaphoton (another company at basically the same stage of development as Cymer), being a Japanese company, objected to foreign control. Though if ASML knew the protectionist, insular direction the US was going to go they probably would rethink their past decisions.
So this retconning that Cymer is really the secret magic of ASML and the Netherlands is just stealing US ingenuity is hilarious stuff.
And for that matter, it is amazing how so often we hear about "American" tech that is actually overwhelmingly combining acquisitions and manpower from abroad. Like is an iPhone an "American" creation? LOL, no.
