This thesis begins with the enhancement of an above-IC silicon carbide-based beam resonator microfabrication process for improved device manufacturability and performance. Technological developments achieve vertical transduction gaps as small as 100 nm as well as full beam resonator metallization so as to significantly reduce electrical loss and operating voltage levels. The improved resonators require polarization voltages less than 6× lower than the initial devices for similar filtering ability, which is critical for eventual fully-monolithic MEMS oscillators. Based on the developed resonators, a functional vacuum sensor is also designed for pressure monitoring from 10 mbar to atmospheric, along with a novel system architecture for temper...
