Patent ID: 7400002

Claim:
A semiconductor device comprising: a semiconductor substrate with a MOSFET; a first electrode of said MOSFET formed on a first principal plane of said semiconductor substrate; a second electrode of said MOSFET formed on a second principal plane of said semiconductor substrate, said second principal plane being opposite to said first principal plane; a first conductive member positioned under said first electrode, said first conductive member being electrically connected to said first electrode; a second conductive member positioned over said second electrode, said second conductive member being electrically connected to said second electrode; a resin body covering said semiconductor substrate, said first and second electrodes and parts of said first and second conductive members; and wherein said second conductive member has a first part and a second part, said second part being contiguous to said first part, one end of said first part extending to an outer edge of said resin body, and said one end connecting to said second part, said first part of said second conductive member has a main portion thereof positioned right above said second electrode and completely inside said resin body, said second part of said second conductive member is positioned outside said resin body, a bottom face of said second part of said second conductive member is positioned below said first principal plane of said semiconductor substrate, a bottom face of said first conductive member is exposed from said resin body, the exposed said bottom surface contains a portion positioned right below said semiconductor substrate, and an entire top face of said first part of said second conductive member is at a same level.
