@cstross @mirrorwitch they’ve built an EUV light source, that’s a critical component but that’s not a EUV machine.
They still need to develop all kind of other sub-systems, some completely unique to EUV.
The EUV radiation is absorbed even by gases, let alone lenses. They need to create the tech for the extremely accurate lenses.
The handling and placement of the wafers must also match the nanometer precision of the projection.
So they have a ways to go before they’ve built a EUV-machine.
To use the precision of an EUV machine you need lots and lots of knowledge, skill and experience. The fabs value that IP very highly and protect it accordingly.
Chips rivalling TSMC’s will take a good while to come out of China’s home-grown machines.
They’ll get there eventually, but the rest of the world isn’t sitting idle while they do…
