Abstract:
A semiconductor module mounting a plurality of semiconductor elements of the same kind, which comprises:a substrate made of an insulator; said plurality of semiconductor elements arranged on said insulator substrate; external connecting terminals electrically connected to an external apparatus; a conductor pattern formed on said insulator substrate, jointed with said external connecting terminals as well as electrically connected with the electrodes of said plurality of semiconductor elements in parallel to form a current path from said external connecting terminals to said plurality of semiconductor elements; wherein said conductor pattern is formed symmetrically in regard to a certain phantom line on said insulator substrate, a plurality of positions on said phantom line and symmetrical in regard to said phantom line being used as jointing zones for said external connecting terminal, current bypass portions to make the individual current paths of said plurality of semiconductor elements in a nearly equal length being provided, the current bypass portion being formed by cutting away a path between a semiconductor element and said jointing zone and providing a bypass for allowing current to flow between the semiconductor element and said jointing zone when the distance between the electrode of the semiconductor element and said jointing zone is shorter than the distances between the electrodes of the other semiconductor elements and said jointing zones (in a case where the semiconductor element has plural electrodes or an expanded electrode the averaged distance being taken as said distance between the electrode of the semiconductor element and said jointing zone.)
