Since you and theobserver want only official or public news, just wait for Huawei produce 3nm chips.
Needs EUV to produce 3nm and beyond.

Needs EUV to produce 3nm and beyond.
As per WSJ, the de-Americanised semiconductor production line in Beijing has gone "beyond the pilot production level, a person familiar with the matter said. "

The article makes no mention of a 28nm SMEE lithography machine, but the whole point of a "de-Americanised" semiconductor production line has to include domestically made Chinese 28nm lithography machines.
SMEE machines have been reported as "arriving/arrived in 2024" from a significant numbers of sources. I doubt we will have any official confirmation for a few years yet.
its better for you to start reading previous pages of this thread and if you have time. you should start this thread from page 1.. very informative especially for new members.. will clear all your doubts and questions ..
CIOMP is the source of this news.. first LPP EUV prototype coming soon.
CIOMP = Changchun Institute of Optics, Fine Mechanics and Physics.
it's a black box model, government forbid any public announcement.
Even a few years later it remains to be true.
we can theorize based on the type and the amount chips China output in the future.
SMEE machines have been tested for a manufacturing process raging from 55nm, that was tested 2021 I guess, to 28nm is the current production line and 14-7nm will be the near future production line. SMEE officially itself stated that, the problem is that people have trouble picking up the clues or don't want believe.
". . . but the whole point of a "de-Americanised" semiconductor production line has to include domestically made Chinese 28nm lithography machines." Doesn't de-Amercanized typically mean ASML but no LAM, AMAT, etc?
Also, on the SMEE DUVi comment from yesterday re: yield rates that was written in Mandarin(?), what was the basis for the 70% yield comment at 28 nm now? I don't recall ever seeing such a comment here. Not that I am complaining.

Nope you can't give statement without linking to the sources I assume comes from leakers and social media.
There is domestic and de-Americanised.
As now domestic are lines to basically put to work domestic equipment in harmony to solve issues as they come, one of those lines was make by a consortium of equipment companies led by Naura and SMEE, there is another made by the Shanghai IC innovation center. From 55nm to 28nm. Getting ready for 14nm to 7nm.
De-Americanised are lines made because there is no to other options with US sanctions, they have to remove US equipment or risk worse sanctions or even death.
Thats not a source. What you posted is literally the same as the description in this YouTube video by some rando.
