Power semiconductor module with insulation shell support for plural separate substrates
First Claim
1. A power module comprising, in combination, a plurality of power semiconductor die each having a bottom surface and a top surface;
- an insulation support shell;
a plurality of thermally conductive semiconductor die support means for receiving the bottom surfaces of respective ones of said power semiconductor die; and
a printed circuit board containing a control circuit thereon for controlling the operation of said plurality of power die;
said printed circuit board disposed in a plane and parallel to the plane of said die support means;
said printed circuit board having a plurality of spaced openings therein;
said insulation support shell having a plurality of coplanar openings therein which are each centered on a respective one of the openings in said printed circuit board;
said plurality of thermally conductive support means being disposed and fixed within respective ones of said openings in said insulation shell and being electrically insulated from one another by said insulation shell; and
wire bond means extending through said openings and connecting said control circuits to respective ones of said power semiconductor die.

Abstract
A power semiconductor device module has a plurality of spaced thermally supported substrates mounted within coplanar openings in an insulation support shall and electrically insulated from one another by the body of the insulation support shell. Each of the substrates may be a separate metal heatsink or a separate IMS sheet. Each of the substrates may receive one or more semiconductor die. A printed circuit board containing control circuits for the die is mounted above the plane of the substrate and contains openings in registry with each substrate for wire bonding the control circuits to the die. The structure permits the reduction in area of any IMS substrate or permits the elimination of the IMS.
