Abstract:
1. A multi-chip press-connected type semiconductor device comprising: a plurality of active element chips to control an electric current flowing in one direction; a plurality of diode chips that transmit the current in a direction opposite to the current transmitting direction of said active element chip; and electrode plates for said active element chip and for said diode chip, said electrode plates pressing from above and under said plurality of active element chips and said plurality of diode chips which are interposed therebetween; wherein said diode chips are disposed in all of outermost peripheral chip disposing positions respectively having at least one side which is not adjacent to other chips and in internal chip disposing positions surrounded by said outermost peripheral chip disposing positions, and wherein said diode chips are disposed in said internal chip disposing positions in order of total number of other chips from smaller that an observed chip is adjacent to at its side or its vertex.
