Abstract:
A passive component integrated circuit chip formed on an insulative substrate includes a first conductive metallic layer on a major surface of the substrate; a layer of dielectric material on top of the first conductive metallic layer; a second conductive metallic layer on top of the formation of dielectric material; a layer of insulative material on top of the layer of dielectric material and on and around the second conductive metallic layer, but not completely covering the second conductive metallic layer; a conductive via in contact with a portion of the second conductive metallic layer left uncovered by the layer of insulative material; a resistive layer on top of the layer of insulative material and in contact with the conductive via; a conductive contact in contact with the resistive layer; and a passivation layer on top of the resistive layer so as to provide a seal between the resistive layer and the conductive contact. Conductive end terminations are advantageously formed on the ends of the substrate to terminate selected conductive contacts and/or conductive metallic layers.
