Chinese EUV light source showcased at CIIF; supply chain visibility read as a proximity signal
teortaxesTex · x · 2026-10-15
Langdao Silex showed its Flint-LPP EUV light source at CIIF 2026: FlintNano already in production, FlintMicro still in validation, alongside Glow MOPA lasers up to 20 kW. Commenters note 20 kW is far from enough for EUV and Langdao isn't a major EUV light-source supplier. The original poster argues the real signal is that supply-chain players are willing to publicly demo at all — plus Huawei talking about domestic EUV development this week — suggesting things are getting close.
