Abstract:
A power semiconductor device module includes, among other parts, a DMB structure. The DMB structure includes a ceramic sheet, a top metal plate that is directly bonded to the top of the ceramic, and a bottom metal plate that is directly bonded to the bottom of the ceramic. A power semiconductor device die is attached to the top metal plate. The bottom surface of the bottom metal plate has a plurality small cavities. When the bottom metal plate is attached to another metal member, a material between the plate and the member (for example, thermal grease or a PCM or solder) is forced into the cavities. This results in an improvement in thermal transfer between the plate and the member. Such cavities can alternatively, or in addition, be included on a metal surface other than a DMB, such as the bottom surface of a baseplate of the module.

Claim (Index 2):
The power semiconductor device module of  claim 1 , further comprising:\n an insulative housing; wherein the bottom metal plate of the DMB and the metal baseplate are disposed so that an amount of thermal grease is in contact with both a top planar surface of the metal baseplate and the bottom surface of the bottom metal plate.
