  • Patent number: 9953961
    Abstract: A semiconductor device can reduce the number of bonding wires. The semiconductor device includes two or more semiconductor elements each of which has electrodes on a first main surface and a second main surface, an electrode plate that has one surface which is bonded to electrodes on the first main surfaces of the semiconductor elements, with a first bonding material layer interposed therebetween, and extends over the electrodes on the first main surfaces of the two or more semiconductor elements, and a conductive plate that includes a first lead terminal and a semiconductor element bonding portion which is bonded to electrodes on the second main surfaces of the semiconductor elements. A second bonding material layer is interposed therebetween, and is connected to the electrodes on the second main surfaces of the two or more semiconductor elements.
