Abstract: An ultrasonic transducer is described. The ultrasonic transducer comprises a membrane and a substrate disposed opposite the membrane such that a cavity is formed therebetween. The substrate comprises an electrode region and pedestals protruding from a surface of the substrate and having a height greater than a height of the electrode region, the pedestals being electrically isolated from the electrode region.

Abstract: An ultrasonic transducer device includes a bottom electrode layer of a transducer cavity disposed over a substrate. The bottom electrode layer includes a bottom layer of a first type metal; a top layer of the first type metal; a second type metal disposed between the bottom layer and the top layer; and at least one intermediate layer of the first type metal disposed between the bottom layer and the top layer, the at least one intermediate layer configured so as to define at least two discrete layers of the second type metal.
