Etching (microfabriion) - Wikipedia

2019-5-13 · Etching is used in microfabriion 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.
