Structure to achieve high-Q and low insertion loss film bulk acoustic resonators |
摘要 |
A film bulk acoustic resonator is formed on a substrate. The film bulk acoustic resonator includes a layer of piezoelectric material having a first surface proximate the substrate, and a second surface distal from the substrate. The first conductive layer deposited on the first surface of the piezoelectric material includes a first portion having a surface on a different plane than a surface associated with a second portion.
