Abstract:
1. A MEMS resonator device, comprising: a substrate; an electrode comprising a first microstructure supported by the substrate; an electro-mechanically resonant element comprising a second microstructure spaced from the first microstructure by a gap and configured for mechanical, resonant vibration of the second microstructure that varies the gap during operation; a disabled shunt coupled to the electrode or the resonant element, the disabled shunt being disabled to enable the resonant vibration but otherwise configured to protect the electrode and the resonant element from damage from an electrostatic charge imbalance before the operation of the MEMS resonator device; and a cap mounted to the substrate to define a sealed cavity in which the electrode, the resonant element, and the disabled shunt are enclosed; wherein the disabled shunt comprises a fuse link spaced from the substrate by a gas within the sealed cavity.
