Abstract
A transducer assembly in which an electric current is passed through plating solution in recesses of a metal substrate to plate electrical contact bumps having bump fronts in the recesses and exposed bump backs. The transducer is partially formed on the substrate, sealing the exposed bump backs. One or more vacuum processes are performed to complete formation of the transducer. At least a portion of the metal substrate is etched away to expose the bump fronts of the electrical contact bumps.
