Abstract
Provided are a semiconductor device capable of reducing damage on a resin case by heating during manufacture and a method of manufacturing a semiconductor device capable of reducing damage on a resin case by heating during manufacture. A semiconductor device includes a base plate, an insulating substrate, a semiconductor element, and a resin case. The base plate includes first and second regions whose positions differ from each other in a plan view. The insulating substrate is bonded on an upper surface of the second region. The insulating substrate includes a circuit pattern on an upper surface. The semiconductor element is bonded on the circuit pattern. The resin case is bonded on an upper surface of the first region. Thermal resistance between the upper surface and a lower surface of the first region is higher than thermal resistance between the upper surface and a lower surface of the second region.
