Abstract
A semiconductor module includes a laminated substrate having an insulating plate, a circuit pattern arranged on an upper surface of the insulating plate and a heat dissipating plate arranged on a lower surface of the insulating plate. The semiconductor module also includes a semiconductor device having a collector electrode arranged on its upper surface, having an emitter electrode and a gate electrode arranged on its lower surface, and bumps respectively bonding the emitter electrode and the gate electrode to an upper surface of the circuit pattern. Each of the bumps is made of a sintered metal such that the bump is formed to be constricted in its middle portion in a thickness direction orthogonal to a surface of the insulating plate.
