  • Publication number: 20230040316
    Abstract: A semiconductor device includes a semiconductor element, a first wiring member, a second wiring member, and a terminal. The semiconductor element includes a first main electrode and a second main electrode on a side opposite from the first main electrode. The first wiring member is connected to the first main electrode. The terminal has a first terminal surface connected to the second main electrode and a second terminal surface. The second terminal has four sides. Two of the four sides are parallel to a first direction intersecting the thickness direction, and other two sides of the four sides are parallel to a second direction perpendicular to the thickness direction and the first direction. The second wiring member is connected to the second terminal surface of the terminal through solder, and has a groove. The groove overlaps one or two of the four sides of the second terminal surface.
