Patent ID: 7855451

Claim:
A device having a contact structure, comprising: a substrate of the circuit supporting type with a conductive layer formed on the substrate; a power electronic semiconductor chip component having upper and lower opposing surfaces with the lower surface in contact with the conductive layer formed on the substrate and the upper surface of the chip component including an electrical contact surface facing away from the conductive layer formed on the substrate; an insulating layer of electrically insulating material attached onto the substrate and to the component such that an element of the insulating layer extends over a surface contour which includes contact between the insulating layer and each of a portion of the substrate, a portion of the conductive layer formed on the substrate and the electrical contact surface of the chip component which faces away from the conductive layer formed on the substrate, wherein the electrical contact surface of the component remains at least partially free of the insulating material, wherein a thickness of the insulating layer covering a straight-edged area of the substrate differs by less than 50% from a thickness of the insulating layer covering a straight-edged area of the component; and a conducting layer of electrically conductive material applied onto the insulating layer and onto the contact surface such that the contact surface is electrically contacted by the conducting layer.
