Patent ID: 7554210

Claim:
A semiconductor device comprising: a semiconductor chip including first and second principal surfaces, a first electrode formed on the first principal surface, and a second electrode formed on the second principal surface; a first conductive lead frame including a first heat sink portion connected to the first electrode and a first terminal portion in which the first sink portion entirely covers the first electrode and is unified with the first terminal portion; a second conductive lead frame including a second heat sink portion connected to the second electrode and a second terminal portion in which the second heat sink portion entirely covers the second electrode and is unified with the second terminal portion; a housing which is provided with front, side and rear surfaces to hold the semiconductor chip and is formed not to cover part of surfaces of the first and second heat sink portions in order to expose the first and second heat sink portions from the front and rear surfaces of the housing, respectively; a third electrode on the first principal surface; and a third lead frame including a top plate portion connected to the third electrode and a third terminal portion.
