    Abstract: In a semiconductor device, a first to a sixth switching elements are joined to a second main surface of a substrate with their electrode surfaces facing the second main surface of the substrate. Non-electrode surfaces of the switching elements are provided with respective heat spreaders joined thereto. Each of the heat spreaders is constituted of a heat spreader main body and a pair of standing portions. The heat spreader main body is formed in a cuboid having rectangular flat surfaces that are elongated in one direction. The standing portions are standing on both edges of a surface of the heat spreader main body.

    Abstract: In a driving unit of an electromechanical motor unit, a semiconductor chip and a smoothing capacitor are joined to a second main surface of a substrate having a first main surface and the second main surface. The semiconductor chip includes a first end portion facing the second main surface, and a second end portion on the opposite side of the semiconductor chip from the first end portion. The smoothing capacitor includes a third end portion facing the second main surface, and a fourth end portion on the opposite side of the smoothing capacitor from the third end portion. The semiconductor chip is thermally connected to a bottom wall portion of a cover member, at a position closer to the second main surface than the fourth end portion is. The bottom wall portion is thermally connected to the motor housing via a sidewall portion of the cover member.
