You're wrong, your parent is correct. NL government had to block sales of ASML EUV machines to China on the US's request since they didn't want to enable China build advanced chips.

ASML definitely wanted to sell to China to increase their quarterly revenues but couldn't because the US owns the IP for the EUV tech and ASML's EUV light sources are made by CYMER in the US, which ASML bought but they're still under US trade restrictions.

So no, ASML and the NL government have to dance according to the moves dictated by the US gov as they own the keys to EUV tech, not ASML/NL.

In the grand scheme you are correct - there is enough US corporations' tech in ASML machines so that the US government has enough leverage to force ASML to comply with its export restrictions.

But your details aren't exactly right, I think. Cymer builds light sources for DUV, not EUV. The EUV light sources are built by Trumpf in Germany, at least as far as I know.

You might want to read the situation and history in ASML's own words:

You're incorect. Trumpf doesn't make EUV light sources, just lasers. Cymer builds the EUV light sources, by blasting microparticles of tin with said Trumpf lasers to generate EUV light.

> at least as far as I know.

You could have also googled this to factcheck before posting if you were unsure ;)

Since ASML builds/integrates the machine, is there any reason why they couldn’t just pull out the EUV laser from the machine, but keep the trumpf lasers, zeiss mirrors and everything else. Then China could just copy the “shooting tin droplets with a laser at 50khz” part.
