Abstract:
A semiconductor device comprising:a plurality of semiconductor units each of which includes a semiconductor element, a contact terminal block, and a positioning guide, said semiconductor element comprising a semiconductor chip and a support plate, said semiconductor chip including a first main electrode and a control electrode disposed on a first main surface thereof, and a second main electrode disposed on a second main surface thereof, said support plate being secured to a surface of said second main electrode for applying a pressure to the semiconductor chip and serving as a conductor and a heat radiator, said contact terminal block being disposed on a surface of said first main electrode of said semiconductor chip, for applying a pressure to the semiconductor chip and serving as a conductor and a heat radiator, said positioning guide positioning said support plate and said contact terminal block on the surface of said first main electrode;a flat package comprising first and second common electrode plates and an insulating outer sleeve that surrounds the first and second common electrode plates, said flat package incorporating therein said plurality of semiconductor units that are arranged side by side, said first and second common electrode plates being in pressure contact with the contact terminal blocks and the support plates, respectively, of all of said semiconductor units; andpositioning and thermal-stress reducing means for positioning the support plates of the semiconductor elements in a horizontal direction, without interfering with the positioning guides, and reducing a thermal stress applied to a peripheral portion of a contact interface between the contact terminal block and the semiconductor chip due to heat generated during intermittent flow of current through a load.
