Publication number: 20220224308Abstract: Methods of manufacturing an acoustic wave device are disclosed. An anti-reflection layer can be formed over a conductive layer that is over a piezoelectric layer. The conductive layer can include aluminum, for example. The anti-reflection layer can remain distinct from the conductive layer after a heating process. A photolithography process can pattern an interdigital transducer of the acoustic wave device from one or more interdigital transducer electrode layers that include the conductive layer. The anti-reflection layer can reduce reflection from the conductive layer during the photolithography process.Type: ApplicationFiled: March 31, 2022Publication date: July 14, 2022Inventors: Satoru Matsuda, Tatsuya Fujii, Yoshiro Kabe, Kenji Nagano
