Etching Processes

Etching is a process used in manufacturing to remove specific areas of material from a surface, often in electronics and microfabrication. It involves applying a chemical solution or physical method to selectively dissolve or carve away parts of a material like metal, silicon, or glass. This controlled removal creates precise patterns or features necessary for the device's function. There are two main types: wet etching, which uses liquid chemicals, and dry etching, which employs gases or plasma. Etching is essential for building intricate, miniaturized components in modern technology.
