  • SINGLE CRYSTAL MICROMECHANICAL RESONATOR AND FABRICATION METHODS THEREOF
    Publication number: 20170054432
    Abstract: The present invention relates to a single crystal micromechanical resonator. In particular, the resonator includes a lithium niobate or lithium tantalate suspended plate. Also provided are improved microfabrication methods of making resonators, which does not rely on complicated wafer bonding, layer fracturing, and mechanical polishing steps. Rather, the methods allow the resonator and its components to be formed from a single crystal.
