Heard some crazy stuff about how Chinese nationals were touring an advanced chip fap research lab associated with a Bay Area university, thanks to a "grant" given by a university in Shenzhen Seems like the result of that "lucky" relationship https://x.com/I_loves_deep_nn/status/1898247993121452314?s=19

hyperbolic imo generating the EUV light isn't the hardest part (nor does wallplug efficiency really matter?) not that i disagree with the trend of china catching up on tech

If the hardest part is mechatronics, that's really just a matter of time since China has the most advanced consumer electronic supply chain in the world, and a boatload of very motivated people to figure it out If it's lithography or die design, that seems like knowhow they can more easily "acquire" (or already have), using money and influence to gain necessary access

I am somewhat out of date on this but my understanding is that the optics are the hard part, which won’t directly benefit from mechatronics progress

Ok So the OP recast from Twitter is that they made hella progress on optics, so I assumed you meant that you thought other parts were harder such as systems integration of a $400m+ machine

I agree that optics are the most "hard science" part of chip fab, so thus seeing this type of progress by Chinese fabs is alarming

I read the op tweet as saying they had made progress in generating the euv beam with more efficiency, which is different from what I was referring to which is the optics for using the beam

How would they test it without the optics?

Oh you can detect the generation of the euv light easily. The optics (lenses / mirrors) that allow it to pattern a chip with precision, reliability, and durability are a different beast
