Abstract:
1. A method of manufacturing a device having a contact structure, the device comprising: a component having an electrical contact surface, wherein the component is a power semiconductor; and a substrate, the component arranged on the substrate, the method comprising: attaching a contiguous insulating layer of electrically insulating material to the substrate and to the component such that the electrical contact surface of the component remains at least partly free of insulating material, wherein the insulating material covers edges of the component facing away from the substrate; and applying a contiguous conducting layer of electrically conductive material onto the insulating layer and onto the contact surface, wherein attaching the insulating layer results in a free conduct surface comprising at least 60% of an extent of the component and applying the conducting layer includes arranging at least two part conducting layers having different electrically conductive materials one above the other.
