The process of photolithography
Webbför 2 dagar sedan · Lithography is the process of transferring a photomask design onto a wafer's surface. In lithography, an ultraviolet laser beam is directed at the photoresist on the wafer after passing through a... 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 …
