Abstract:
A power semiconductor device module comprising a thin flat thermally conductive substrate having a bottom surface engageable by a heat sink surface and a top surface receiving at least one power semiconductor die in surface-to-surface contact; the top surface of said at least one semiconductor die having control electrode means; an enlarged planar printed circuit board having electrical components thereon for the control of said at least one power semiconductor die; said printed circuit board having an opening therein of a shape which at least approximates the shape of said thermally conductive substrate; said printed circuit board being disposed in a plane parallel to the plane of said substrate and being placed above said substrate; at least one wire bond connection extending from at least one of said components on said printed circuit board, through said opening in said printed circuit board and to said control electrode means on said semiconductor die; and an insulation shell for supporting said substrate; said insulation shell having an opening therethrough for exposing said bottom surface of said substrate around a peripheral edge thereof and for receiving a projecting mesa of a heat sink which engages said bottom surface of said substrate; the upper surface of said insulation shell receiving and supporting the bottom surface of said printed circuit board.
