    摘要： A SAW filter is fabricated at a wafer level for providing desirable temperature characteristics. The filter includes a piezoelectric substrate bonded to a carrier substrate, wherein the coefficient of thermal expansion of the carrier substrate is less than the coefficient of thermal expansion of the piezoelectric substrate. Interdigital transducers are formed on the piezoelectric substrate so as to form a SAW composite die structure. A cap substrate having a coefficient of thermal expansion similar to that of the carrier substrate is bonded to the SAW composite die structure for enclosing the interdigital transducers. Plated vias form signal pad interconnects to input and output pads of the interdigital transducer and a sealing pad formed on the surface of the piezoelectric substrate bonds the SAW composite die structure to the cap substrate.

    摘要： An electro-mechanical device package includes a cap material permanently bonded to a device wafer encapsulating an electromechanical device. An intermediate material is used to bond the device and capping material together at a low temperature, and a structure including the intermediate material emanating from either the device or cap material, or both, provides an interlocking at the bonding interface. One package includes a reusable carrier wafer with a similar coefficient of thermal expansion as a mating material and a low cost cap wafer of different material than the device wafer. A method for temporarily bonding the cap material to the carrier wafer includes attaching the cap material to the carrier wafer and is then singulated to mitigate thermal expansion mismatch with the device wafer.
