That is just about mianzi, no worries. Anyways, after reading the articles, it sounds like they are using older ASML lithography equipment, rather than homemade equipment from SMEE. Which is strange, because they announced they can do 3nm, but they are only putting 28nm into production this year. https://abachy.com/news/chinas-28nm-lithography-machine-expected-2024 https://abachy.com/news/chinas-28nm-lithography-machine-expe...
- alephnerd 3y agoI mean it makes sense. Most vendors can do 3nm, but probably not at production scale other than ASML. 28nm is very worrying from a NatSec standpoint though - way more than leading edge nodes - as that enough to produce a Sandy Bridge or Maxwell type architecture, which meets the needs for most American defense applications (eg. drones, precision missiles, C-RAM, etc) Russia manufactures their Elbrus-8s architecture using 28nm lithography as well, and that's the backbone for most of their newer precision, electronics, and avionics weapons systems.
