Etching
Etching is a process used in manufacturing to create detailed designs or patterns on a surface, such as metal, glass, or semiconductor wafers. It involves applying a protective mask to the substrate, then exposing it to chemicals or acids that dissolve the unprotected areas. This selective removal of material reveals the desired pattern or features. Etching is essential in industries like electronics, jewelry, and printing, allowing for precise and intricate designs or circuit patterns to be formed with accuracy and efficiency.
