Film bulk acoustic resonator package and method of fabricating same

摘要

A microfabricated device has a first substrate, a second substrate, a film bulk acoustic resonator (FBAR) device, and a circuit. The second substrate is bonded to the first substrate to define a chamber. The FBAR device is located on a surface of the first substrate and inside the chamber. The circuit is located on a surface of the second substrate and inside the chamber. An electrical connection connects the circuit and the FBAR device.
