The process of photolithography
WebbThe word lithography (Greek for the words stone [ lithos] and to write [ gráphein ]) refers to the process invented in 1796 by Aloys Senefelder, who inked Bavarian limestone and transferred a carved image from stone onto paper. The most widely used form of lithography is photolithography. WebbPhotolithography, also called optical lithography or UV lithography, is a process used in microfabrication to pattern parts on a thin film or the bulk of a substrate (also called a wafer). It uses light to transfer a geometric pattern from a photomask (also called an optical mask) to a photosensitive (that is, light-sensitive) chemical photoresist on the …
