摘要:
A power semiconductor module includes a main substrate and power semiconductor chips. Each power semiconductor chip is bonded to the main conductive layer with the first power electrode. A first group of the power semiconductor chips is connected in parallel via the second power electrodes and a second group of the power semiconductor chips is connected in parallel via the second power electrodes. The module also includes a first insulation layer and a first conductive layer overlying the first insulation layer as well as a second insulation layer and a second conductive layer overlying the second insulation layer. The first conductive layer provides a first gate conductor area and a first auxiliary emitter conductor area for the first group. The second conductive layer provides a second gate conductor area and a second auxiliary emitter conductor area for the second group.
