Abstract

An acoustic resonator has a piezoelectric plate attached to the surface of the substrate except for a portion of the piezoelectric plate forming a diaphragm spanning a cavity in the substrate. An interdigital transducer (IDT) formed on the plate has interleaved fingers on the diaphragm with first parallel fingers extending from a first busbar and second parallel fingers extending from a second busbar of the IDT. The first and second busbars of the IDT terminate in beveled corners that extend off of the diaphragm as side edges of the busbars that form angles with a perimeter of the cavity.
