Abstract
A semiconductor device has a sealing body formed of an insulating resin and a semiconductor chip positioned within the sealing body. A gate electrode and a source electrode are on a first main surface of the semiconductor chip and a back electrode (drain electrode) is on a second main surface thereof. An upper surface of a portion of a drain electrode plate that projects in a gull wing shape is exposed from the sealing body and a lower surface thereof is connected to the back electrode through an adhesive. A gate electrode plate projects in a gull wing shape on an opposite end side of the sealing body and is connected to the gate electrode within the sealing body. A source electrode plate projects in a gull wing shape on the opposite end side of the sealing body and is connected to the source electrode within the sealing body.
