Abstract
A semiconductor power module includes a substrate formed of metallized ceramic, at least one semiconductor power component with a base surface soldered to the metallized ceramic, and at least one heat conduit integrated into the semiconductor power module. The heat conduit includes a condensation area having a larger surface than the base surface, over which dissipation heat from the semiconductor power component is distributed.
