Patent ID: 7385467

Claim:
A component comprising: a plurality of resonators that form at least a portion of a circuit; wherein the plurality of resonators comprise layer structures above a wafer, wherein each of the layer structures comprises first and second electrode layers that comprise electrodes, and at least one piezoelectric layer that is between the first and second electrode layers; a dielectric layer above the plurality of resonators, the dielectric layer comprising a hermetic encapsulation for the plurality of resonators, the dielectric layer comprising a material and having a thickness that results in a first acoustic impedance, the material comprising a low-K dielectric, the dielectric layer having top and bottom surfaces that substantially follow a topology of the plurality of resonators; and a metal layer above the dielectric layer, the metal layer comprising a material and having a thickness that results in a second acoustic impedance, the second acoustic impedance being higher than the first acoustic impedance, the metal layer and the dielectric layer being parts of an acoustic mirror; wherein the wafer has a surface comprising solderable contacts that are electrically connected to the plurality of resonators or to one or more of a plurality of active and/or passive components integrated with the plurality of resonators in circuits; and wherein the plurality of resonators are electrically interconnected by electrode layers of the resonators to form the at least a portion of a circuit.
