WebEtching is the process of taking off unwanted substrate sites from a substrate, plays a very important role in nanofabrication. This process is of two types: dry and wet etching. In dry or plasma etching technique, plasmas or reactive gases are used whereas wet etching involves using reactive liquid chemicals or etchants. WebThe etch process can be described as a sequence of three steps: (1) the etchant diffuses from the bulk liquid to the surface being etched, (2) the surface reaction takes place, and (3) the by-products diffuse out to the bulk liquid. The … WebJun 24, 2024 · Step 1: Create Or Find A Circuit Diagram. Before you start drawing wires and stuff, you need to know what circuit you want to build. So you need a circuit diagram.
