Abstract

In this paper, an electrostatic silicon micro actuator has been designed and fabricated using the micro machining technology. The actuator consists of two counter electrodes. One is an Al film deposited on a pyrex glass, and the other is a circular corrugated diaphragm with boron doped. The diaphragm is fabricated by boron etch stop technique using an anisotropic etchant, EPW.
