"Web1. Process Description. Photochemical etching is the selective removal of metal from the surface of a metal sheet using a chemical reagent. To create an etched pattern on the surface of a metal, we need a way to transfer the required image or pattern onto the metal surface; this is achieved using photoresist technology.
