Lithographic processing
WebIn the lithographic process, a photoresist is first uniformly applied to the substrate by spin coating or spraying. With the aid of a structured template, typically a chrome-coated glass mask, the open areas are exposed to UV light or particle irradiation, whereby the solubility of the resist changes. WebLithography is a planographic printmaking process in which a design is drawn onto a flat stone (or prepared metal plate, usually zinc or aluminum) and affixed by means of a …
