  • Film bulk acoustic resonator (FBAR) devices with temperature compensation
    Patent number: 7561009
    Abstract: The temperature-compensated film bulk acoustic resonator (FBAR) device comprises an FBAR stack that comprises an FBAR characterized by a resonant frequency having a temperature coefficient and a temperature-compensating layer comprising doped silicon dioxide. The FBAR comprises opposed planar electrodes and a piezoelectric element between the electrodes. The piezoelectric element has a temperature coefficient on which the temperature coefficient of the resonant frequency of the FBAR depends at least in part.
