Claim 10:
11. A method of fabricating a bulk acoustic wave resonator structure for a fluidic device comprising:
disposing a first conductive material over a portion of a first surface of a substrate to form at least a portion of a first electrode, the substrate having a second surface opposite the first surface;
disposing a piezoelectric material over the first electrode;
disposing a second conductive material over the piezoelectric material to form at least a portion of a second electrode, wherein the second conductive material extends substantially parallel to the first surface of the substrate, the second conductive material at least partially extending over the first conductive material, wherein an overlapping region of the first conductive material, the piezoelectric material, and the second conductive material forms a bulk acoustic wave resonator, the bulk acoustic wave resonator having a first side and an opposing second side;
disposing an acoustic energy management structure over a first side of the bulk acoustic wave resonator; and
disposing a third conductive material over a portion of the second conductive material that extends beyond the bulk acoustic wave resonator, wherein the third conductive material forms an interconnect extending above the acoustic energy management structure in a direction substantially perpendicular to the first surface of the substrate.
