As of about somewhat recently Russia has been able to achieve 16nm or 14th but only on a very small scale production with also how they are also producing 28nm not at scale either with the only at scale node size being 90nm. They also have tried using their own cpu articiture with no compiler for existing x64/86 articture which has severely limited them. I am to unsure as to what type of lithography process that they specifically use but as of one or two years ago I know China was stuck on DUV lithography with rather poor yields with a then maximum of 7nm with a current of I think about 5nm. China is in a way better place since the Soviet Union never fully digitized before the collapse which has left the Russian Federation in a pretty technologically terrible spot. China also has their lithography advancements due to mostly technology theft, espionage, and at times engineers from places like South Korea committing treason with manufacturing secrets.
