摘要： Heat radiation surfaces 7b and 8b of electrode lead frames 7 and 8 make thermal contact with heat radiation members 301 via insulation sheets 10 to dissipate heat from a power semiconductor element 5 to the heat radiation members (thick portions 301). Each of exposed areas of the heat radiation surfaces 7b and 8b and a surface 13b of a mold material (sealing material 13) adjacent to the exposed area produce an uneven step from which either one of the exposed area and the surface 13b adjacent to the exposed area projects. The step side surface formed between the convex surface and the concave surface of the uneven step has an inclined surface 7a or 13a so configured that an obtuse angle can be formed by the inclined surface and the convex surface and by the inclined surface and the concave surface for each.

摘要： A power module includes: a sealing body including a semiconductor element having a plurality of electrode surfaces, a first conductor plate connected to one electrode surface of the semiconductor element via solder, and a sealing material for sealing the semiconductor element and the first conductor plate, the sealing body having at least a first surface and a second surface on the opposite side of the first surface; and a case for housing the sealing body. The case is configured by a first heat radiation plate opposed to the first surface of the sealing body, a second heat radiation plate opposed to the second surface of the sealing body, and an intermediate member that connects the first heat radiation plate and the second heat radiation plate. The intermediate member has a first thin section having thickness smaller than the thickness of the first heat radiation plate, more easily elastically deformed than the first heat radiation plate, and formed to surround the first heat radiation plate. The sealing body is pressed against and fixed to the second heat radiation plate via the first heat radiation plate by elastic force generated in the first thin section.

摘要： A double-face-cooled semiconductor module with an upper arm and a lower arm of an inverter circuit includes first and second heat dissipation members, each having a heat dissipation surface on one side and a conducting member formed on another side through an insulation member. On the conducting member on the first dissipation plate is provided with a fixing portion that fixes a collector surface of the semiconductor chip and a gate conductor connected to a gate terminal of the semiconductor module. The gate electrode terminal and the gate conductor are wire bonded. The conducting member on the second heat dissipation member is connected to an emitter surface of the semiconductor chip connected to the first heat dissipation member. The productivity and reliability are improved by most of formation operations for the upper and lower arms series circuit on one of the heat dissipation member.
