Abstract:
1. A semiconductor device, comprising: a first semiconductor chip having a first front surface including a first electrode pad and a second electrode pad formed thereover, and a first back surface arranged on the opposite side to the first front surface and including a third electrode formed thereover, the first semiconductor chip including a transistor element electrically coupled with the first and second electrode pads and the third electrode; a second semiconductor chip having a second front surface including a fourth electrode pad formed thereover, and a second back surface arranged on the opposite side to the second front surface and including a fifth electrode formed thereover, the second semiconductor chip including a diode element electrically coupled with the fourth electrode pad and the fifth electrode; a first metal plate having a first chip mounting part including the first semiconductor chip mounted thereover, and electrically coupled with the third electrode of the first semiconductor chip; a second metal plate having a second chip mounting part including the second semiconductor chip mounted thereover, and electrically coupled with the fifth electrode of the second semiconductor chip; a lead group including a lead electrically coupled with the first semiconductor chip, and a lead electrically coupled with the second semiconductor chip; and a sealing body for sealing the first and second semiconductor chips, and respective portions of a plurality of the leads, wherein the first and second metal plates are electrically isolated from each other, and are arranged adjacent to each other along a first direction, wherein the lead group is arranged in such a manner as to face to the first metal plate and the second metal plate along a second direction orthogonal to the first direction, and respective leads are arranged along the first direction, and wherein, in plan view, the width in the first direction of a portion of the first metal plate including the first chip mounting part is larger than the width in the first direction of a portion of the second metal plate including the second chip mounting part.
