Bulk Micromachining

Bulk micromachining is a fabrication process used to create tiny structures and features within a solid material, such as silicon, by removing large amounts of material through chemical etching. This technique involves exposing the desired areas to etchants that selectively dissolve the material, resulting in precise, three-dimensional micro-scale structures. It’s widely used in manufacturing microelectromechanical systems (MEMS) like sensors, actuators, and microfluidic devices. The process benefits from high precision and control, enabling the creation of complex devices with miniaturized components essential for modern electronics and sensing technologies.
