    Abstract: A micro-electromechanical systems (MEMS) transducer device mounted to a package substrate includes an active transducer having a resonator stack formed over a cavity through a transducer substrate, and a stress mitigation structure between the transducer substrate and the package substrate. The stress mitigation structure reduces stress induced on the transducer substrate due to mismatched coefficients of thermal expansion (CTEs) of the transducer substrate and the package substrate, respectively.

    Abstract: A device includes a first wafer, a second wafer, a gasket bonding the first wafer to the second wafer to define a cavity between the first wafer and the second wafer, and an acoustic transducer disposed on the first wafer and disposed within the cavity between the first wafer and the second wafer. One or more apertures are provided for communicating an acoustic signal between the acoustic transducer and an exterior of the device. An aperture may be formed in the cavity itself, or the cavity may be hermetically sealed. An aperture may be formed completely through the first wafer and located directly beneath at least a portion of the acoustic transducer.
