Patent ID: 7125798

Claim:
A method of manufacturing a semiconductor module comprising: preparing a semiconductor device comprising: a plurality of conductive paths having a first face and a second face opposed to the first face, a first circuit element electrically connected to the first face of the conductive paths, wherein the first circuit element includes a semiconductor element and a passive element which are electrically connected by one or more of the conductive paths and are both located on a first side of the conductive paths, and an insulating resin supporting the conductive paths and the first circuit element, and having a first surface and a second surface with a shape substantially the same as the first surface, wherein each surface of the insulating resin except the first surface is only insulating resin; and an electrode formed by exposing the second face of the conductive paths from the first surface of the insulating resin; mounting a second circuit element on the electrode exposed at the first surface of the insulating resin as a mounting face; and providing an insulating film to cover the first surface but to expose a region of the electrode to be connected with the second circuit element.
