Abstract

In one embodiment a power semiconductor module includes a substrate having a first substrate side for carrying an electric circuit and having a second substrate side being located opposite to the first substrate side. The second substrate side has a flat surface and is adapted for coming in contact with a cooler. A cooling area that is surrounded by a connecting area is located at the second substrate side. A first casing component of the cooler is connected to the second substrate side at the connecting area and a second casing component is connected to the first casing component such that a cooling channel for providing the cooling area with cooling fluid is provided between the first casing component and the second casing component. A cooling structure can be welded to the cooling area at the second substrate side.
