COMBINED RESONATORS AND PASSIVE CIRCUIT COMPONENTS ON A SHARED SUBSTRATE

摘要

This disclosure provides implementations of electromechanical systems combined resonator and passive circuit component structures, devices, apparatus, systems, and related processes. In one aspect, the device includes a piezoelectric resonator structure formed over an insulating substrate. A portion of the piezoelectric resonator structure is spaced apart from the substrate by a first gap. A passive circuit component structure such as an inductor or a capacitor is formed over the insulating substrate. A portion of the passive circuit component structure is spaced apart from the substrate by a second gap. The first gap and the second gap are defined by removal of a sacrificial (SAC) layer.
