A RESONATOR INCLUDING A PASSIVATION LAYER, A VIBRATING SENSOR INCLUDING SUCH A RESONATOR, AND A METHOD OF MANUFACTURE

摘要

A resonator has a body of silicon-based material with at least one resonant part having at least one portion covered in an electrical conduction layer and at least one portion not covered in a conduction layer. The portion of the resonator not covered in a conduction layer is covered in a passivation layer in such a manner that, in the resonant part, the silicon-based material is completely covered by the conduction layer and by the passivation layer in combination. A vibrating sensor is also provided which includes such a resonator and a method of fabricating the resonator.
