Abstract

This paper presents a novel design of poly-silicon corrugated diaphragm which can be used for micro-machined microphone. The microphone is built on a corrugated polysilicon diaphragm with eight-leg supports. In order to reduce the residual stress, the diaphragm is designed with a corrugated ring. A theoretical calculation is presented to show the result of the new design; the FEM simulation results have shown that the eight-leg support diaphragm is the best compared to other two types. The eight-leg-support diaphragm has more deformation than the all-edge-support diaphragm. The fabrication process is also presented in order to confirm that the new design is possibly built by the new technology.
