摘要
New developments in deep reactive ion etching (DRIE) technology, when combined with silicon fusion bonding (SFB), make it possible, for the first time, to span nearly the entire range of microstructure thicknesses between surface and bulk micromachining, using only single-crystal silicon. The combination of these two powerful micromachining tools forms a versatile new technology for the fabrication of micromechanical devices. The two techniques are described and a process technology is presented. Some of the experimental structures and devices that have been demonstrated using this new process technology are discussed.
