Lithography basics
WebPhoto (or UV) lithography is the technique of pattering through the use of a light sensitive polymer (called photoresist) and a stencil (called a photomask). Through a series of chemical treatments this pattern is inscribed by either etching away of exposed areas or the deposition of new material to fabricate the desired device.
