Abstract:
Provided is a power semiconductor device which is able to have improved connection reliability between a wiring line and an electrode of a power semiconductor element in comparison to conventional power semiconductor devices. This power semiconductor device is provided with: a semiconductor element; an insulating substrate having an electrode layer to which the semiconductor element is bonded; an external wiring line which is solder bonded to an upper surface electrode of the semiconductor element and has an end portion for external connection, said end portion being bent toward the upper surface; and a frame member which is affixed to the electrode layer of the insulating substrate. The frame member has a fitting portion that is fitted with the end portion for external connection; and the external wiring line has at least two projected portions that protrude toward the semiconductor element.

Claim (Index 1):
A power semiconductor device comprising:\n an insulating substrate configured to include a first conductor layer and a second conductor layer provided respectively on opposite surfaces in a thickness direction of an insulating layer; a plurality of semiconductor elements configured to be joined to the first conductor layer via a first anchoring layer; an external connecting member configured to be commonly used with the semiconductor elements, and have an element coupler and an external connection end, the element coupler configured to extend along the first conductor layer with the semiconductor elements positioned between the external connecting member and the first conductor layer, and be joined to the semiconductor elements via a second anchoring layer, the external connection end configured to bend an end of the element coupler in the thickness direction; and a frame member configured to surround the plurality of semiconductor elements on the first conductor layer and be joined to the first conductor layer via a third anchoring layer; wherein the frame member includes a fitting portion fitted to the external connection end, and the external connecting member includes at least two projections extending toward the semiconductor elements.
