Abstract:
1. A semiconductor device comprising: a semiconductor chip in which a circuit part provided in a center of the semiconductor chip is connected with power-supply lines and power-supply electrodes to supply power from an external power source to the circuit part; a substrate provided for carrying the semiconductor chip thereon and provided so that first terminals disposed in a region encircling the semiconductor chip are electrically connected to the power-supply electrodes; a first opening formed on the power-supply line in a center of the circuit part; a second opening formed on the power-supply line at a peripheral part of the circuit part; and a conductor layer electrically connected to second terminals disposed in the region encircling the semiconductor chip on the substrate, and provided so that the power-supply line in the first opening and the power-supply line in the second opening are connected to each other by the conductor layer.
