WebJul 31, 2012 · Optical lithography is a photon-based technique comprised of projecting an image into a photosensitive emulsion (photoresist) coated onto a substrate such as a silicon wafer. It is the most widely used lithography process in the high volume manufacturing of nano-electronics by the semiconductor industry. Optical lithography’s ubiquitous use ... WebIntroducing Optical Lithography Lithography creates a resist image on the wafer. The subsequent etching, lift off, or ion implantation process is masked by the resist image at the areas dictated by the lithography mask. Hence, the thin film material on the wafer is selectively removed, built up, or its characteristics are selectively altered.
