Abstract: A film bulk acoustic wave resonator of the invention includes a substrate; a resonant structure provided on the substrate constituted by a lower electrode, a piezoelectric film and an upper electrode; and an acoustic multilayer of a plurality of reflective films provided between the substrate and the resonant structure. At least one of the reflective films of the acoustic multilayer has a specified crystal plane orientation, and an X-ray rocking curve full width at half maximum that is preferably not greater than 10 degrees, and more preferably is not greater than 3 degrees. This makes it possible to obtain better resonance characteristics than in the case of the prior art, by increasing the efficiency with which bulk waves propagating towards the substrate are reflected.

Abstract: A film bulk acoustic wave resonator wafer of the present invention prevents electric discharge from occurring in the process of fabricating a film bulk acoustic wave resonator, thereby enhancing product reliability and yield. The film bulk acoustic wave resonator wafer of the present invention comprises a substrate, a lower electrode and an upper electrode provided on the substrate and a piezoelectric film provided between the lower electrode and upper electrode. The lower electrode and upper electrode are shorted through a window provided in the piezoelectric film. Since the lower electrode and upper electrode are therefore kept at the same potential, no electric discharge passing through the piezoelectric film occurs even during the formation of a protective film covering the upper electrode, dicing of the substrate and other processes in which discharge has heretofore been likely to occur.

Abstract: A film bulk acoustic resonator of the present invention includes an upper electrode 104, a lower electrode 102, and a piezoelectric film 103 as well as an acoustic multilayer 120 that are provided between the upper electrode 104 and the lower electrode 102. Thus, a distance between the upper electrode 104 and the lower electrode 102 is extended by a thickness of the acoustic multilayer 120, and electrostatic capacitance between the upper electrode 104 and the lower electrode 102 per unit area can be reduced accordingly. Therefore, an electrode area can be increased as compared to when there is no acoustic multilayer 120, and an influence of grains of a piezoelectric material can be reduced.
