Abstract
An acoustic wave device has a substrate, an optional functional layer disposed over at least a portion of the substrate, a piezoelectric layer disposed over at least a portion of the functional layer and/or substrate, and an interdigital transducer electrode disposed on the piezoelectric layer. The piezoelectric layer has an outer edge spaced inward of an outer edge of the substrate, the outer edge of the piezoelectric layer being tapered at an angle relative to a surface of the substrate to thereby reduce an acoustic reflection magnitude at said outer edge of the piezoelectric layer.
