[Prior Art] Generally, a packaged semiconductor component is molded with a resin, and depending on the type, it has an electrode exposed on the side surface of the semiconductor component in a planar manner from the molding portion. In such a semiconductor component, the semiconductor component is attached to the radiator plate in a state where the planar electrode is in contact with the electrode of the radiator plate, so that the semiconductor component is cooled and electrically connected through the radiator plate. An example of this is shown in FIG. In the figure, 1 is a heat sink electrode, 2 is a semiconductor component (internal structure is omitted in the drawing), 3 is a resin mold portion of the semiconductor component 2, and 4 is a planar electrode exposed on the side surface of the semiconductor component 2. Reference numeral 5 denotes an external connection terminal of the semiconductor component 2, 6 is a screw, 7 is a washer, 8 is a hole of the semiconductor component 2, 9 is a screw hole of the heat sink electrode 1, and the planar electrode 4 is attached to the heat sink electrode 1. The semiconductor component 2 is fastened to the heat sink plate electrode 1 by the screw 6 in the state of being in contact with the heat sink plate 1. In this case, if the planar electrode 4 of the semiconductor component 2 and the resin mold part 3 are formed flush with each other, there is not much problem, but the planar electrode 4 of the semiconductor component 2 may be changed due to the manufacturing variation of the semiconductor component 2. In the case where the resin mold portion 3 is formed in a concave shape inward of the resin mold portion 3, conduction failure is likely to occur between the semiconductor component 2 and the heat dissipation plate electrode 1.
