Abstract
An ultrasonic transducer device includes a bottom electrode layer of a transducer cavity disposed over a substrate, and a plurality of vias that electrically connect the bottom electrode layer with the substrate. A bottom cavity layer is disposed over the bottom electrode layer, and one or more openings are formed in the bottom cavity layer so as to expose a region of the bottom electrode layer, wherein locations of the one or more openings are segments that are disposed proximate an outer perimeter of the transducer cavity and substantially correspond to locations where the plurality of vias are not disposed directly beneath.
