Abstract
A film bulk acoustic wave resonator (FBAR) is disclosed with recessed and raised frame portions in the piezoelectric film. The FBAR can include a substrate, the piezoelectric film supported to oscillate in a direction opposite to a main surface of the substrate, and a pair of top and bottom electrodes formed respectively on top and bottom surfaces of the film. The recessed frame portion and the raised frame portion can be formed in the film to extend adjacent to each other along a periphery of an active region of the film oscillating during an operation of the film on a top surface of the top electrode.
