Power semiconductor module for improved thermal performance

摘要

Semiconductor module has a first member, a second member, a conductor column extending in the vertical direction between the first member and the second member and a sealing resin covering a first conductor layer and a first power device of the first member, a second conductor layer and a second power device of the second member and the conductor column. Positions of the first power device and the second power device on the horizontal plane are shifted, the second conductor layer is not provided in the vertical direction from a first connection part connected to the first power device, and the first conductor layer is not provided in the vertical direction from a second connection part, connected to the second power device, of the second power device.
