Still waiting until SMEE finally announces and then after that it is proven that it has built a DUVi machine equivalent at least to the mid range level of performance of those of ASML, Canon, and Nikon, using entirely domestically made equipment. When this happens, China will at least be free, because doing so will mean that China will also have solved its lapses in aligning and other necessary metrological equipment in chip making.
@Weaasel it seems you missed a lot information on this thread or you don't read previous pages of this thread ..When it finally happens it will be a massive moment in history for China. But I feel when it happens you won't feel the hype because few will cover it.
When the ws15 engines were ready for j20, for some reason there was not much impact as expected. Maybe it's China's strategy to keep everything under wraps even big breakthroughs. That way by the time you know China has it, it's too late. Better being like India and announcing every single thing for the world to hear.
SMEE last year officially announced top Metrology tool ''SHM800'' for chip making.. it is said to be pair with SSA800i.. SMEE specifically mentioned 7nm .. so metrological equipment aligning with Litho have solved already..

---------------------------------------------------------------------------------------------------------
all core and critical components of SSA800i are locally developed and produced by Chinese companies/institutes.. like lens , optical system , light source .. we have complete information available on this thread..
Havok confirmed this news- all technical bottleneck regarding immersion machine have solved. back in 2022.. so there is no technological hurdle in immersion machine..
so now its all about verification time period and work for volume production. this thing always takes time..

AECC didn't announce WS-10 engine completion news, never announced mass production. never disclose WS-10 engine specification. same happening with WS-20/WS-15 engines ..
SMIC didn't announce Finfet production.. still not acknowledge about 7nm .. though its been a year since Mate60 released.. LOL
this is how we Chinese people works..
so probably SMEE might never announce SSA800i.. though we have information from suppliers announcement about volume production .. this year SMEE is all set to start volume production of Lithography .. this is confirmed information..
