  • Patent number: 9171768
    Abstract: A semiconductor device includes an insulating substrate joined with a semiconductor chip, a case covering a surface of the insulating substrate where the semiconductor chip is joined, and a control terminal in which one end portion is electrically connected to the semiconductor chip, and another end portion passes through the case and is exposed to outside of the case. A portion of the control terminal exposed to the outside of the case includes a cut-out section where a part of the exposed portion is cut out, and a blocking section formed by bending a portion surrounded by the cut-out section and remaining on the control terminal. The blocking section contacts the case from the outside of the case and blocks a movement of the control terminal.

  • Patent number: 9167699
    Abstract: Aspects of the invention are directed to a power module including a metal base, an insulating substrate which is attached to the metal base, a semiconductor chip and a control terminal which are attached to a circuit pattern of the insulating substrate, and a resin case which is attached to the metal base. The control terminal can include a penetration portion which penetrates a cover of the resin case, an L-shaped processed portion which is connected to the penetration portion, and a connection portion which is connected to the L-shaped processed portion. A protrusion portion can be installed in a portion of the control terminal, which penetrates the cover. The protrusion portion can be in contact with a protrusion receiving portion which is configured with a front surface of the cover. The L-shaped processed portion can be in contact with a convex portion in a rear surface of the cover.
