Claim 10:
11. A method of manufacturing a bulk acoustic wave (BAW) assist filter structure, comprising:
stacking at least one BAW resonator over at least one integrated passive device (IPD), the at least one BAW resonator comprising a substrate, at least one transducer over the substrate, the at least one transducer comprising a first electrode, a second electrode, and a piezoelectric layer between the first electrode and the second electrode; and
electrically coupling the at least one BAW resonator to an electrical circuit of the at least one IPD, wherein the at least one IPD comprises conductive landing pads and wherein the at least one BAW resonator comprises pillars aligned with and electrically coupled to the conductive landing pads of the at least one IPD.
