A structure and method for creating a contact between a conductive layer and a pad for dissipating electrostatic charges comprising the steps of, forming a pad and a composite insulating layer between and over conductive plates on a substrate, wherein the insulating layer isolates and protects the conductive plates and pad from damage, the insulating layer comprising a dielectric region underlying a conductive layer. A passivation layer is formed over at least a portion of the conductive layer and a photoresist is patterned over at least a portion of the passivation. An opening is etched through the passivation and the insulating layers, wherein the photoresist and the conductive layer serve as masks. Finally, a conductive material is deposited in the opening to form an electrical contact between the pad and the conductive layer.
