Patent ID: 11410959

Abstract:
A semiconductor module includes a substrate, a first semiconductor device, a second semiconductor device, a first wiring, a second wiring, a first intermediate layer, a second intermediate layer, and a third wiring. The first semiconductor device is provided on the substrate. The first semiconductor device has a first surface facing the substrate and has a second surface on a side opposite to the first surface. The second semiconductor device is adjacent to the first semiconductor device and is provided on the substrate. The second semiconductor device has a first surface facing the substrate and has a second surface on a side opposite to the first surface. The first wiring is provided on the second surface of the first semiconductor device and is coupled to the second surface of the first semiconductor device. The second wiring is provided on the second surface of the second semiconductor device and is coupled to the second surface of the second semiconductor device. The first intermediate layer is provided on the first wiring and is coupled to the first wiring. The second intermediate layer is provided on the second wiring and is coupled to the second wiring. The third wiring has a plate part on the first intermediate layer and on the second intermediate layer. The plate part is coupled to the first intermediate layer and to the second intermediate layer. The third wiring has a pillar part or a wall part between the plate part and the substrate. The third wiring has thermal conductivity due to coupling of the plate part and the substrate via the pillar part or the wall part.
