Abstract:
A semiconductor module in which at least two semiconductor elements arranged along a certain direction, and at least two electrode pad regions arranged along a direction approximately perpendicular to said certain direction, are respectively connected in parallel to each other, characterized in comprising:a) a base plate; b) a lower layer substrate comprising: a first insulation substrate in approximately rectangular shape with the back surface fixed on said base plate; a first and a second electrode pads in approximately identical shapes disposed on a front surface of said first insulation substrate along one side of said first insulation substrate so as to be juxtaposed to each other in this order from a corner portion of said one side; and a first and a second wires which are juxtaposed to each other along other side of said first insulation substrate approximately perpendicular to said one side and including said corner portion of said one side, said second wire extending by the side of said first and said second electrode pads, and said first wire extending by the side of said first electrode pad with said second wire interposed; c) an upper layer substrate disposed on said lower layer substrate, comprising: a second insulation substrate in approximately rectangular shape; and a first bridge wire connecting said first wire with said first electrode pad and a second bridge wire connecting said second wire with said second electrode pad, which are formed in a back surface of said second insulation substrate; d) a first semiconductor element electrically connected with said first wire and a second semiconductor element electrically connected with said second wire, which are formed in a front surface of said second insulation substrate; and e) a cap disposed on said base plate so as to cover said lower layer substrate, said upper layer substrate, and said first and said second semiconductor elements.
