Abstract:
1. A method for forming a vibrating micromechanical structure, the method comprising: in a base substrate of a Silicon-On-Insulator wafer, machining one or more transmission lines in the base substrate; forming one or more resonator anchors adjacent to a capacitive air gap; to the resonator anchors of the base substrate, coupling a single crystal silicon semiconductor material active layer of a Silicon-On-Insulator resonator wafer having a dielectric layer between a semiconductor material handle layer and the semiconductor material active layer; removing the handle and dielectric layers of the Silicon-On-Insulator resonator wafer; in the single crystal silicon semiconductor material active layer of the Silicon-On-Insulator resonator wafer, silicon dry etch machining a single crystal silicon resonator that is structured to form a filter device.
