US Patent 11189579 Semiconductor module and semiconductor device using the same

A semiconductor module internally includes semiconductor elements and multilayer substrates on which the semiconductor elements are arranged. The semiconductor module further includes, in a case, fastening portions for fastening a cooler such as conductive radiating fins or water-cooling jackets, for example. In the semiconductor module, side faces of heat radiating plates formed on the rear surface sides of the multilayer substrates are electrically connected to the fastening portions in the case by conductive connectors.
