Abstract
A new Fabry–Perot (FP) microcavity structure with a novel single deeply corrugated diaphragm (SDCD) is presented for use in pressure sensing. Both analytical expression and finite‐element model (FEM) are used to evaluate the device's performance. The FP microcavity is fabricated on a single chip using both surface and bulk micromachining techniques. The results show that the signal averaging effect can substantially be reduced for the FP microcavity pressure sensor by the flatness‐enhancing diaphragm structure. © 2003 Wiley Periodicals, Inc.
