Abstract
An acoustic wave device comprises a substrate including a piezoelectric material, interdigital transducer (IDT) electrodes including interdigitated electrode fingers disposed on a surface of the substrate, and a passivation layer formed on tops of the IDT electrodes and on the piezoelectric material in gaps between adjacent IDT electrodes, the passivation film being thicker on the tops of the IDT electrodes than on the piezoelectric material in the gaps between adjacent IDT electrodes to improve an electromechanical coupling factor of the acoustic wave device.
