Wet etching - Citizendia

In microfabrication, wet etching is chemical etching performed with a liquid etchant, as opposed to a plasma. Microfabrication or micromanufacturing are the terms to describe processes of fabrication of miniature structures of Micrometre sizes and smaller In Industry, etching (sometimes called chemical Milling or wet etching) is the process of using Acids bases or other Liquid is one of the principal States of matter. A liquid is a Fluid that has the particles loose and can freely form a distinct surface at the boundaries of In Physics and Chemistry, plasma is an Ionized Gas, in which a certain proportion of Electrons are free rather than being bound See also Etching (microfabrication). Etching is used in Microfabrication to chemically remove layers from the surface of a wafer during manufacturing
