Abstract
An acoustic resonator device includes a bottom electrode disposed on a substrate over an air cavity, a first piezoelectric material layer disposed on the bottom electrode, an electrically-isolated layer of high-acoustic-impedance material disposed on the first piezoelectric material layer, a second piezoelectric material layer disposed on the electrically-isolated layer of high-acoustic impedance material, and a top electrode disposed on the second piezoelectric material layer, where an overlap among the top electrode, the first piezoelectric material layer, the electrically-isolated layer of high-acoustic-impedance material, the second piezoelectric material layer, and the bottom electrode over the air cavity defines a main membrane region.
