Patent ID: 7479691

Claim:
A power semiconductor module comprising: surface-mountable flat external contacts, which provide external contact areas on an underside of the power semiconductor module; and at least one power semiconductor chip, the top side of the power semiconductor chip comprising source contact areas and gate contact areas and the rear side of the semiconductor chip comprising a drain contact area, the flat external contacts comprising top sides arranged in an inner housing plane, the drain contact area of the rear side of the semiconductor chip being fixed on the top side of a drain external contact, and an insulation layer covering the top side and edge sides of the semiconductor chip and also the housing plane whilst leaving free the source and gate contact areas on the top side of the semiconductor chip and also whilst leaving free contact pads on the top sides of the source and gate external contacts, and the insulation layer bridging an interspace between the external contacts in the region of the inner housing plane in approximately planar fashion.
