Patent ID: 7332757

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 with said first electrode; a second conductive member positioned over said second electrode, said second conductive member being electrically connected with said second electrode; and a resin body covering said semiconductor substrate, said first and second electrodes and parts of said first and second conductive members, wherein said second conductive member has a first part and a second part, said second part being contiguous to said first part, said first part is positioned above said second principal plane of said semiconductor substrate, said second part extends downwards from said first part, a top surface of said first part of said second conductive member is exposed from said resin body, the exposed said top surface contains a portion positioned right above said semiconductor substrate, and a bottom surface 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.
