Patent ID: 8441126

Claim:
A semiconductor device comprising: a semiconductor chip including a main surface, a back surface opposed to the main surface and a plurality of electrode pads on the main surface, the semiconductor chip further including a first edge extending in a first direction and a second edge extending in a second direction different from the first direction; a wiring board that is smaller in size than the semiconductor chip, and mounted over the main surface of the semiconductor chip, the wiring board including a first board edge facing the first edge of the semiconductor chip and a second board edge facing the second edge of the semiconductor chip, the wiring board being positioned such that a distance between the first board edge and the first edge of the semiconductor chip is longer than a distance between the second board edge and the second edge of the semiconductor chip, the second board edge of the wiring board being separated from the second edge of the semiconductor chip toward an inside of the semiconductor chip; and a plurality of external terminals on the wiring board, and electrically connected to the electrode pads of the semiconductor chip, respectively.
