Patent ID: 8269331

Claim:
A power semiconductor module, comprising: a power semiconductor element; and a capacitor connected to the semiconductor element; wherein the power semiconductor element and the capacitor each have electrodes joined to each other in the module, and the power semiconductor element is formed on a single semiconductor substrate having first and second main surfaces, the first and second main surfaces facing in opposite directions; the power semiconductor module further comprising: a first electrode through which a main current flows, joined to the first main surface of the single semiconductor substrate; a second electrode through which the main current flows, joined to the second main surface of the single semiconductor substrate; a resin portion sealing the single semiconductor substrate, the capacitor and the first and second electrodes; and a cooler cooling the capacitor and the power semiconductor element; wherein the capacitor includes third and fourth electrodes; the first electrode and the third electrode are joined to each other using a first portion of solder such that the surfaces of the first electrode, the third electrode, and the first portion of solder form a first continuous surface where the first continuous surface is exposed through the resin portion; and the second electrode and the fourth electrode are joined to each other using a second portion of solder such that the surfaces of the second electrode, the fourth electrode, and the second portion of solder form a second continuous surface where the second continuous surface is exposed through the resin portion; the cooler includes: a first cooling portion attached on the first continuous surface and a second cooling portion attached on the second continuous surface.
