Abstract
The semiconductor wafer of the power module is mounted directly, separated only by thermal expansion control layers and insulator layers, on the metal base which has fins or pins integrally formed thereon. This module is mounted on a coolant fluid flow chamber so that the module mounting is not a thermal interface. In this way, maximum power module cooling is achieved with minimum fluid flow.
