Paper Abstract

This paper discusses the use of high power lasers in the manufacture of microelectromechanical systems (MEMS). The ability to process a wide range of materials, and to produce truly three-dimensional structures with tolerances at the micron or sub-micron level, give laser micromachining some key advantages over other more established micromachining techniques. Previous work in this area is reviewed, covering the following topics: use of ablation in the direct fabrication of MEMS devices and to define polymer masters for subsequent replication by electroforming and moulding (the so-called Laser-LIGA process); laser-assisted deposition and etching on planar and non-planar surfaces; laser-assisted manipulation of microparts and laser-assisted assembly.
