Who says there are no lithography machines in Russia?
Let's just say it's not state-of-the-art.
Chips, Russia can also produce, but not the production of high-end chips.
Lithography machine is the core equipment for the production of large-scale integrated circuits, manufacturing and maintenance requires a high degree of optical and electronic industrial base, and only a few manufacturers in the world have mastered. Western countries have no restrictions on the purchase of low - and medium-end lithography machines in Russia.
