Bulk acoustic wave components

Abstract:

Aspects of this disclosure relate to bulk acoustic wave components. A bulk acoustic wave component can include a substrate, at least one bulk acoustic wave resonator on the substrate, and a cap enclosing the at least one bulk acoustic wave resonator. The cap can include a sidewall spaced apart from an edge of the substrate. The sidewall can be 5 microns or less from the edge of the substrate.
