Definition
In terms of a production engineering process (Allen 2004), etching is better defined as a material removal process by accelerated, controlled corrosion, comprising a heterogeneous chemical reaction in which a liquid (or, more rarely, a gas) reacts with a solid material and oxidizes it to produce a soluble (or volatile gaseous) reaction product.
Theory and Application
Etching as a Process Employed in Manufacturing and Production Technology
The “art” of etching (Chamberlain 1972) was developed into a production process for the graphic arts, printing, and die-making industries, utilizing chemical etching and photoresist imaging to produce printing plates and dies by etching the surface of metals such as copper, zinc, and magnesium alloys. This process is commonly known as photoengraving (Wallis and Cannon 1969).
A further variation of this technique, developed in the late 1950s, led to etching completely...
