Plasma Etching

Term from Semiconductor Manufacturing industry explained for recruiters

Plasma Etching is a crucial process used in making computer chips and electronic components. Think of it as a very precise way of carving or removing tiny bits of material using a special gas called plasma, similar to how a sculptor carefully removes material to create their artwork. This technique is essential because it helps create the microscopic patterns needed for modern electronics. When reading resumes, you might also see it called "dry etching" or "plasma processing." It's different from wet etching, which uses liquid chemicals instead of plasma gas.
