Etching (microfabrication)Wikipedia

Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module and every wafer undergoes many etching steps before it is complete. For many etch steps part of the wafer is protected from the etchant by a "masking" material which resists etching.
