This paper introduces a micromachining manufacturing process of quartz vibrating beam accelerometer. This work focuses on thin metal film depositing and wet etching processes. Some possible reasons that affect the performance of the thin metal film are analyzed by theory and the solutions are proposed. The accuracy of depth and profile of the beam are proved to be important for the wet etching by simulation.
