WebBasics of the Photolithography Process. In the photolithography process, a light source and collimating optical system are used to create an image of a patterned mask onto a substrate coated with a photosensitive polymer layer (photoresist). This illuminated pattern is then transferred into the substrate by a subsequent etching process.
WebDeep- UV photolithography [1–3] has been optimized for the semiconductor industry as a main patterning technology.
