I'm not sure why this is so heavily downvoted - it's an interesting question. The PRC's official position is that Taiwan is part of China, so perhaps Taiwanese equipment does count.

I don't think many equipment makers are Taiwanese. The names I am familiar with are KLA from the US. Tokyo Electron from Japan and ASML from Netherlands. TSMC buys equipment from them and build the fabs. The PRC wants complete vertical integration.

Equipment not product. It started with money going to R&D and scams like epic HSMC https://www.chinatalk.media/p/billion-dollar-heist-how-scamm... but Chinese are patient and real innovation eventually rises to the top. Case in point Made in China 2025 - looked like pipe dream 10 years ago, yet became bitter reality for western component manufacturers.
