Everyone, and I mean everyone, is gated by ASML machines. They can't make nearly enough EUV machines to satisfy the demand. ASML has also not scaled their production nearly as much because they're quite far away from the AGI-pilled companies in the supply chain.
Well, CXMT is not gated by ASML machines because they can't buy them. They can raise their capacity because they have access to the domestically produced steppers. They are not as good as the ASML ones, and if the memory prices were not bonkers, they'd never make a profit using them, but as it is the low yields and high die sizes don't matter.
