Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:(a) preparing a first semiconductor chip which is provided with first a main surface and a second main surface which are opposite to each other, the plane of which is formed in a square and which is provided with plural electrodes arranged along a first side on the side of the first side of the opposite first and second sides of the first main surface, and a second semiconductor chip which is provided with a first main surface and a second main surface which are opposite to each other, the plane of which is formed in a square and which is provided with plural electrodes arranged along a first side on the side of the first side of the opposite first and second sides of the first main surface; and further preparing a lead frame provided with a first lead group and a second lead group which are opposite to each other, and a supporting lead arranged between the first lead group and the second lead group; (b) bonding the second main surface of the first semiconductor chip and the supporting lead in a state that the first semiconductor chip is arranged so that the first side of the first semiconductor chip is located on the side of the first lead group; (c) bonding the first semiconductor chip and the second semiconductor chip in a state that the first main surface of the first semiconductor chip and the first main surface of the second semiconductor chip are opposed so that the first side of the second semiconductor chip is located on the side of the second lead group, the electrode of the second semiconductor chip is located outside the second side of the first semiconductor chip and the electrode of the first semiconductor chip is located outside the second side of the second semiconductor chip; (d) electrically connecting the electrodes of the first semiconductor chip with respective inner parts of leads of the first lead group via conductive wires, and electrically connecting the electrodes of the second semiconductor chip with respective inner parts of leads of the second lead group via conductive wires; and (e) forming a resin sealing body by sealing the first semiconductor chip, the second semiconductor chip, the inner parts of the leads of the first lead group, the inner parts of the leads of the second lead group and the conductive wires with resin.
