But the new chinese maschines are "only" DUV and not EUV, so it will only go to a certain point. Anyway, the current Huawei phones show that even with chips made with DUV you can go pretty far... — Nick Naylor Except DUV can make almost everything EUV makes: it's a question of cost, not capability.
With multipatterning (exposing the same layer multiple times), immersion DUV produces 7nm chips and can in principle reach 5nm. As you yourself hint, SMIC makes Huawei's 7nm smartphone and — Arnaud Bertrand
