Abstract
An acoustic wave resonator is disclosed. The acoustic wave resonator can include a plurality of interdigital transducer electrodes and a multilayer piezoelectric substrate (MPS) adjacent the plurality of interdigital transducer electrodes. The MPS includes a first substrate layer of a piezoelectric material, and a second substrate layer of silicon that is bonded to the first layer. The silicon has a cut direction and/or acoustic wave propagation direction that is different from those of a silicon substrate. The silicon substrate has a cut direction and a propagation direction property defined by the silicon cut angle of {100} and the propagation direction <110>.
