Surface micromachining

Surface micromachining is a manufacturing technique used to create tiny structures and devices on the surface of materials, typically silicon. It involves layering materials, like metals and polymers, and then using processes like etching to remove unwanted parts, leaving behind precise features. This technology is crucial in making small components for sensors, microelectronics, and MEMS (Micro-Electro-Mechanical Systems), which are used in everything from smartphones to medical devices. Essentially, surface micromachining allows engineers to build intricate, miniature machines on a chip, enabling advancements in various fields.
