Patent ID: 7663175

Claim:
A semiconductor integrated circuit device comprising: a plurality of power supply wire layers including a first potential power supply wire and a second potential power supply wire formed in different layers; and at least one capacitor contact wire extending from one of the first and second potential power supply wires toward the other one of the first and second potential power supply wires and forming a capacitor between each capacitor contact wire and its surrounding capacitor contact wires, wherein: the power supply wire layers each include a plurality of meandered first potential power supply wires, each having a bent middle portion, and a plurality of meandered second potential power supply wires, each having a bent middle portion, with the plurality of meandered first potential power supply wires and the plurality of meandered second potential power supply wires arranged alternately in each of the power supply wire layers; the plurality of power supply wire layers include a first layer and an adjacent second layer; the bent middle portions of the first and second potential power supply wires in the first layer and the bent middle portions of power supply wires having the same potential in the second layer are opposed to each other and connected to each other by a plurality of contact wires; the first potential power supply wires and the second potential power supply wires have portions exclusive of the bent middle portions that are respectively opposed to power supply wires having different potentials in the second layer; and the at least one capacitor contact wire includes a plurality of capacitor contact wires extending from each of the first and second potential power supply wires in the first layer toward the power supply wires having different potentials in the second layer.
