Abstract:
1. A power semiconductor module, comprising: a substrate; at least one power semiconductor component on the substrate; and a composite film arranged on the at least one power semiconductor component such that the at least one power semiconductor component is between the substrate and the composite film, wherein the composite film has a thin circuit-structured logic metal layer, a comparatively thick circuit-structured power metal layer, and a thin electrically insulating film disposed between the circuit-structured logic metal layer and the circuit-structured power metal layer, the composite film having contact nubs for bonding to the at least one power semiconductor component, wherein feedthrough holes are provided between the logic metal layer and the power metal layer, the electrically insulating film defining a recess in the region of each feedthrough hole that is free of the logic metal layer, and wherein a flexible segment of a thin wire extends through the region that is free of the logic metal layer and through the recess in the electrically insulating film and is bonded to bonding sites at each of the logic metal layer and the power metal layer.
