i think its KLA tools. two domestic players reached on 28nm inspection tools
LAM and AMAT already covered by NAURA/AMEC..
The biggest issue in the Chinese semiconductor industry right now is lithography, most of the tools can be used in more advanced nodes with some upgrades, but the overlay issue is really holding everyone back.
i think 28nm non american is basically qualified at this point. They have enough lithography machines around. That's not a problem. The issue is 14nm and then 7nm. For that, it's not entirely clear to people outside what really is the limiting factor. But it's quite clear lithography machine is not the limiting factor
I think Tianjin and Beijing fabs are not running yet.
havok said ICRD was testing 55nm on non american production line，that was 2023. Don't know their progress，hopefully they can test 28nm this year
no, he said that was fully domestic line. Big difference.
40nm de-americanized line qualified in 2022. 28nm achieved that status in 2023 based on what Paul Triolo heard when he was talking to people in China.
didn't I just tell you to raise the level of your post?
I would suggest you spend more time just reading this thread rather than asking stupid questions or making comments that are clearly wrong based on easily searchable comments from this forum. You will be officially warned the next time this happens.
Fully domestic is way more important than it used to be ever since the US got the European and Japanese tool vendors to follow their sanctions on sales to China. Just a de-americanized line doesn't cut it anymore.
One big question I have is if SMIC managed to get the tools they needed for all their massive 28nm GigaFabs in time or not. From what I understand they should still be able to buy these even with the sanctions if things continue as they are. But this ramp up is pretty important since it will make SMIC a leading player in legacy nodes.
Then there is the question with regards YMTC and CXMT if they can get the other tools than the lithographers from Chinese vendors or not. So that they can ramp up their production facilities.
