DRIE
DRIE (Deep Reactive Ion Etching) is an important manufacturing process used to create tiny structures in computer chips and electronic devices. Think of it like a very precise way of carving extremely small patterns into silicon, similar to how a sculptor carefully removes material to create detailed artwork, but at a microscopic level. It's particularly useful when companies need to make deep, straight-sided holes or channels in silicon wafers, which are essential for many modern electronic devices. When you see this term in resumes, it usually indicates experience with advanced semiconductor manufacturing equipment and processes.
