WebExtreme ultraviolet lithography (also known as EUV or EUVL) is an optical lithography technology used in semiconductor device fabrication to make integrated circuits (ICs). It uses extreme ultraviolet (EUV) wavelengths near 13.5 nm, using a laser-pulsed tin (Sn) droplet plasma, to produce a pattern by using a reflective photomask to expose a … WebLithography의기술개발에전기를마련한Stepper의시대가시작되었다.
