I doubt they have anything viable right now. Having actually watched these EUV machines get installed and seen the insides, there is a reason nobody else has made them yet. They’re incredibly complex, requiring extreme care and precision. I was at GF Fab 8 when they got their EUV machines; it was a process, I’ll tell you that much. Custom cranes had to be installed in the fab just to facilitate any sort of meaningful work on them, and they were down a lot.
(…) Unlike ASML’s LPP (laser-produced plasma) method, which relies on high-energy lasers and complex FPGA-based controls, the report indicates that China’s LDP (laser-induced discharge plasma) offers a simpler design, smaller footprint, better energy efficiency, and potentially lower production costs.
(…) set for trial production for the third quarter, 2025, with mass manufacturing aimed for 2026.

i absolutely believe you that the technology of these old machines is much too complex and this is an argument why the Chinese have to make a better technology to replace it :
