    摘要: A semiconductor device superior in heat dissipating performance and permitting reduction of the packaging cost is provided. The semiconductor device comprises a sealing body formed of an insulating resin, a semiconductor chip positioned within the sealing body, the semiconductor chip having a gate electrode and a source electrode on a first main surface thereof and having a back electrode (drain electrode) on a second main surface thereof, a drain electrode plate projecting in a gull wing shape on one end side of the sealing body, an upper surface of a portion of the drain electrode plate which portion is positioned in the sealing body being exposed from the sealing body and a lower surface thereof being connected to the back electrode through an adhesive, a gate electrode plate projecting in a gull wing shape on an opposite end side of the sealing body and being connected to the gate electrode within the sealing body, a source electrode plate projecting in a gull wing shape on the opposite end side of the sealing body and being connected to the source electrode within the sealing body, a depression formed in the surface of the drain electrode plate within the sealing body and filled with the resin which forms the sealing body, and a projecting portion formed on the surface of the drain electrode plate within the sealing body and engaged with the sealing body. The drain electrode plate and the source electrode plate branch into plural branch pieces (leads) serving as gull wing-shaped surface mounting terminals.
