Abstract:
1. A structure comprising: a substrate having a device layer comprising a substantially freely suspended micro-electro-mechanical systems (MEMS) resonator body of a MEMS resonator device; a dielectric layer over the device layer and comprising a gate dielectric for a gate of a field effect transistor (FET), and further comprising a dielectric plate for at least one transducer of the MEMS resonator device, such that the dielectric layer includes both the gate dielectric and the dielectric plate; and a conductive layer comprising a gate electrode over the gate dielectric for the gate, and further comprising a transducer plate over the dielectric plate for the at least one transducer, such that the conductive layer includes both the gate electrode and the transducer plate, wherein the field effect transistor is formed on the device layer and apart from the substantially freely suspended MEMS resonator body.
