Abstract

Methods of manufacturing bulk acoustic wave resonators are disclosed. During a common processing step, a first patterned mass loading layer for a first bulk acoustic wave resonator is formed and a second patterned mass loading layer for a second bulk acoustic wave resonator is formed. The first patterned mass loading layer has a different density than the second patterned mass loading layer.
