🌿 lithos(@lithos_graphein):🧵1/ An interesting EUV lithography paper just dropped from the Department of Radiophysics at the University of Nizhny Novgorod. It is not a tweak to ASML’s architecture. It is a radically different theory of the lens: stop counting mirrors, and start counting how many times each photon is allowed to bounce.
