A chemical substance which is rendered insoluble upon exposure to light. By exposing photoresist through a mask, electrical circuits can be created by washing the unexposed areas and etching the material below. Photoresists are usually optimized for specific regions of the UV spectrum specified as UVC, UVB, and UVA depending on the type of lamp emp...
