摘要: Acoustic resonator devices and filters are disclosed. A piezoelectric plate is attached to a substrate, a portion of the piezoelectric plate forming a diaphragm spanning a chip cavity in the substrate. A first conductor pattern is formed on a surface of the piezoelectric plate. The first conductor pattern includes interleaved fingers of an interdigital transducer on the diaphragm, and first contact pads. An interposer has walls on its back surface that are attached to the chip front surface and that surround the diaphragm. An interposer cover layer spans the walls creating an enclosed interposer cavity over the diaphragm. A second conductor pattern formed on the walls and cover layer includes second contact pads on the interposer back surface. Electrical connections between the second contact pads and connection points on the chip electrically connect the first contact pads to respective ones of the second contact pads.

摘要: Methods of making acoustic resonator devices and filters are disclosed. A method of fabricating an acoustic resonator device includes fabricating an acoustic resonator chip including: attaching a back surface of a piezoelectric plate to a front surface of a substrate, such that portions of the piezoelectric plate form at least first and second diaphragms spanning at least first and second cavities, and forming a first conductor pattern as one or more conductor layers on the piezoelectric plate. The first conductor pattern includes at least first and second interdigitated transducers (IDTs) and a first plurality of contact pads. The method further includes fabricating an interposer having front and back surface and a second plurality of contact pads on the interposer back surface, forming conductive balls, and bonding each of the first plurality of contact pads to a respective pad of the second plurality of contact pads using the respective conductive ball.
