Patent ID: 7247929

Claim:
A semiconductor device comprising: an element of a semiconductor switching element that includes first and second surfaces, wherein a first electrode is exposed on the first surface, a second electrode is exposed on the second surface, and a control electrode is exposed on a control-electrode-exposing surface that is one of the first and second surfaces; two radiating members between which the element is disposed, wherein the two radiating members are electrically connected with the first and second electrodes, respectively, wherein each of the two radiating members has an inward and outward surfaces, wherein the inward surface is closer to the element than the outward surface; a mold resin member filling a space between the two radiating members; an insulating layer formed on an insulated portion of at least one of the inward surfaces of the two radiating members; and a conductive layer formed on the insulating layer and electrically connected with the control electrode and an input portion protruding from the mold resin member, wherein one of the first and second electrodes is electrically connected with a non-insulating portion of the inward surface on which the insulated portion is located, wherein no insulating layer is formed on the non-insulating portion, the input portion includes a lead terminal for control signals, and a first end of the lead terminal is protruding from the mold resin member while a second end of the lead terminal is, with the conductive layer, overlapped and electrically connected using a conductive connection member.
