【Abstract】 The pulsed laser microfabrication technologies and their applications in MEMS manufacture are reviewed. The high energy pulsed lasers have 3 dimension microstructure fabrication capabilities with micro/sub micro precision, and are applicable to a wide range of materials. Therefore, compared with traditional microfabrication technologies, such as lithography, etching, bulk and surface silicon micromaching processes, pulsed laser microfabrication processes are quite unique.The pulsed laser direct fabrication of MEMS, laser LIGA processes, laser assisted etching and deposition processes, laser assisted micromanipulation and assembly technologies are discussed.更多还原
