Micro machining for micro electro mechanical systems. Silicon grown either as a monocrystal or as a polycrystal is the familiar material for micromachining performed in this case with standard techniques for silicon processing. Any micromachining technique removes a part of a bulk substrate or of a thin film using various etching methods. Bulk micromachining starts with a silicon wafer or other substrates which is selectively etched using photolithography to transfer a pattern from a mask to the surface. In the more than two decades since a team of researchers from the center for ultrafast optical science at the university of michigan first demonstrated the use of a femtosecond laser for micromachining 1 this technology has clearly made its evolutionary step from scientific equipment to a reliable.
