  • Methods of manufacturing acoustic wave device with anti-reflection layer
    Patent number: 11855603
    Abstract: 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.
