Patent ID: 7342267

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 over said second electrode, said first conductive member being electrically connected with said second electrode; and a second conductive member positioned under said first principal plane of semiconductor substrate, said second conductive member being electrically connected with said first electrode, wherein said first conductive member contains a first part, a pair of second parts and a pair of third parts, said first part is positioned above said second principal plane of said semiconductor substrate, said semiconductor substrate is positioned between said pair of second parts and between said pair of third parts, each of said third parts is positioned below said first part, and each of said third parts is connected via a respective one of said second parts to said first part.
