A semiconductor device (8) has an insulating layer (16) overlying a semiconductor substrate (12). The insulating layer has a first opening that defines an aperture (18) extending from the insulating layer to the semiconductor substrate, and at least a first portion of a first conductive terminal (42) is disposed in the aperture. A second conductive terminal (52) has a second portion (28) disposed in the aperture. The second portion of the second conductive terminal is separated from the first conductive terminal by a composite dielectric layer including a nitride layer (32) and an oxide layer (30). In one approach, the oxide layer is formed by the oxidation of the second portion of the second conductive terminal.
