摘要： A power module includes a pair of power devices that are stacked with a plate-shaped output electrode arranged therebetween, and an N-electrode and a P-electrode that are stacked with the pair of power devices arranged therebetween. The output electrode is anisotropic such that the thermal conductivity in a direction orthogonal to the stacking direction is greater than the thermal conductivity in the stacking direction. Also, the output electrode extends in the orthogonal direction from a stacked area where the pair of power devices are stacked. The N-electrode and the P-electrode extend in the orthogonal direction while maintaining an opposing positional relationship.

摘要： A power module includes a semiconductor device having a first and second arms, and gate driving circuit board. The first arm includes a first extending electrode, a first gate electrode of a first power device extending in a direction different from the first extending electrode, and a first output electrode extending in the different direction from the first gate electrode. The second arm stacked on the first arm includes a second extending electrode extending in the first extending electrode extending direction in an insulating state, a second gate electrode of a second power device, extending in the first gate electrode extending direction, and a second output electrode extending in the first output electrode extending direction with electrical connection thereto. The gate driving circuit board is disposed at the first and second gate electrodes extending side so as to face the semiconductor device.
