Patent ID: 7408251

Claim:
A semiconductor device comprising: a semiconductor chip including a MOSFET; a sealing member sealing the semiconductor chip, said sealing member being formed of an insulating resin and having a top surface, a bottom surface, and four side faces connecting the upper and lower surfaces; a source electrode plate of the MOSFET formed on a bottom surface of the semiconductor chip, a bottom surface of the source electrode plate being exposed from the bottom surface of the sealing member and two terminals of the source electrode plate projecting outside of two side faces of the sealing member; a gate electrode plate of the MOSFET formed on the bottom surface of the semiconductor chip, a bottom surface of the gate electrode plate being exposed from the bottom surface of the sealing member and two terminals of the gate electrode plate projecting outside of said two side faces of the sealing member; a drain electrode plate including a first portion, a second portion, and a third portion, the first portion being formed on a top surface of the semiconductor chip, the second and third portions extending downward from the first portion towards the bottom surface of the semiconductor chip to sandwich the semiconductor chip in-between, at least a pair of drain electrode terminals being connected with the second and third portions respectively, disposed under the semiconductor chip, and exposed from the bottom surface of the sealing member, said drain electrode terminals projecting outside of other two side faces of the sealing member, wherein the source and gate electrode terminals are positioned between the drain electrodes terminals, and wherein one of the electrodes of the semiconductor chip on the bottom surface of the semiconductor chip is not physically connected but electrically connected to the source, gate or drain electrode plate through an electrically conductive adhesive, and said adhesive is sandwiched between the semiconductor chip and the source, gate or drain electrode plate.
