Claim 14:
15. A device comprising:
an acoustic resonator comprising a first electrode, a second electrode and a piezoelectric region between the first and second electrodes;
an insulating layer on the second electrode; and
an interconnection metal layer on the acoustic resonator, connected by a via to the first electrode or the second electrode and having a portion extending onto the insulating layer adjacent the via that serves as a first capacitor electrode of a capacitor disposed laterally adjacent the acoustic resonator and having a portion of the second electrode as a second capacitor electrode of the capacitor and a portion of the insulating layer between the first and second capacitor electrodes as a dielectric of the capacitor, wherein the first electrode is formed from a first conductive layer, wherein the second electrode is formed from second conductive layer, wherein the via connects the interconnection metal layer to a portion of the second conductive layer electrically connected to the first electrode and wherein the first capacitor electrode overlaps the portion of the second conductive layer electrically connected to the first electrode.
