Abstract: An improvement is achieved in the heat dissipation property of an electronic device including power transistors. A semiconductor module includes first and second packages included in an inverter circuit. In the first package, a semiconductor chip having a high-side power transistor is embedded. In the second package, a semiconductor chip having a low-side power transistor is embedded. At the both wide surfaces of the first and second packages, first metal electrodes electrically coupled to respective collector electrodes of the power transistors and second metal electrodes electrically coupled to respective emitter electrodes of the power transistors are exposed. To the first and second metal electrodes of the first and second packages, four respective bus bar plates having areas larger than those of the first and second metal electrodes are joined.

Abstract: Reliability of a semiconductor module is improved. In a resin mold step of assembly of a semiconductor module, an IGBT chip, a diode chip, a control chip, a part of each of chip mounting portions are resin molded so that a back surface of each of the chip mounting portions is exposed from a back surface of a sealing body. After the resin molding, an insulating layer is bonded to the back surface of the sealing body so as to cover each back surface (exposed portion) of the chip mounting portions, and then, a TIM layer is bonded to an insulating layer. Here, a region of the TIM layer in a plan view is included in a region of the insulating layer.

Abstract: An electronic device includes: a substrate having an upper surface (front surface) on which a semiconductor chip is mounted, and a lower surface (back surface) opposite to the upper surface; and a housing (case) fixed to the substrate through an adhesive material. The housing has through-holes each formed on one short side and the other short side in an X direction. The substrate is disposed between the through-holes. A part of the upper surface of the substrate is fixed so as to face a part of a stepped surface formed at a height different from that of a lower surface of the housing. Further, an interval (distance) between a part (stepped surface) extending along a short side of the housing in the stepped surface and the upper surface of the substrate is larger than an interval (distance) between a part (stepped surface) extending along a long side of the housing in the stepped surface and the upper surface of the substrate.

Abstract: An electronic device includes a first substrate, a wiring substrate (second substrate) disposed over the first substrate, and an enclosure (case) in which the first substrate and the wiring substrate are accommodated and that has a first side and a second side. A driver component (semiconductor component) is mounted on the wiring substrate. A gate electrode of a first semiconductor component is electrically connected to the driver component via a lead disposed on a side of the first side and a wiring disposed between the driver component and the first side. A gate electrode of a second semiconductor component is electrically connected to the driver component via a lead disposed on a side of the second side and a wiring disposed between the driver component and the second side.
