Abstract
A surface acoustic wave device can include a piezoelectric layer, first and second interdigital transducer electrodes in electrical communication with the piezoelectric layer, a reflector positioned between the first and second interdigital transducer electrodes such that the first and second interdigital transducer electrodes and the reflector are aligned along a longitudinal direction, and a temperature compensation layer over the first and second interdigital transducer electrodes and the reflector. The temperature compensation layer has a first region with a first thickness overlapping at least the first interdigital transducer electrode and a first portion of the reflector, a second region with a second thickness overlapping at least the second interdigital transducer electrode and a second portion of the reflector, and a sidewall between the first and second regions. The first thickness is greater than the second thickness. At least a portion of the sidewall extending non-perpendicular to the longitudinal direction.
