Lithography Process Summary Lithography Process Summary - Lithography Coating System - Cheersonic 1. Optical lithography is a patterning process, which uses ultraviolet light to transfer the pattern designed on the lithography or scaled lithography to the photoresist temporarily coated on the surface of the product. 2. Positive photoresist will become soluble after UV light; negative photoresist will become insoluble due to polymer crosslinking. Positive photoresists are more commonly [...]
