    Abstract: A packaged capacitive MEMS sensor device includes at least one capacitive MEMS sensor element with at least one capacitive MEMS sensor cell including a first substrate having a thick and a thin dielectric region. A second substrate with a membrane layer is bonded to the thick dielectric region and over the thin dielectric region to provide a MEMS cavity. The membrane layer provides a fixed electrode and a released MEMS electrode over the MEMS cavity. A first through-substrate via (TSV) extends through a top side of the MEMS electrode and a second TSV through a top side of the fixed electrode. A metal cap is on top of the first TSV and second TSV. A third substrate including an inner cavity and outer protruding portions framing the inner cavity is bonded to the thick dielectric regions. The third substrate together with the first substrate seals the MEMS electrode.

    Abstract: A vibration device includes a substrate, a first drive source, a second drive source, and a membrane. The membrane includes a main portion extending in an in-plane direction, and a damper protruding in a direction perpendicular to a plane of the membrane. The main portion includes a first region disposed on the first drive source, a second region disposed on the second drive source, and a third region disposed between the first region and the second region. The damper includes a first portion connecting the first region and the third region, and a second portion connecting the second region and the third region.

    Abstract: A wafer die assembly includes a first wafer having at least a central cavity defined therein. The wafer die assembly includes a second wafer mounted to the first wafer. At least one of the first or second wafers includes an etched pattern. The etched pattern including at least one peripheral cavity, and a raised area raised relative to the peripheral cavity. A method of assembling a wafer die assembly includes etching a central cavity into a first wafer and etching a pattern into at least one of the first wafer or a second wafer. The first wafer and/or the second wafer includes a raised area raised relative to the peripheral cavity or the central cavity. The method includes bonding the second wafer to the first wafer.
