Patent ID: 7465974

Claim:
An integrated circuit device having a circuit portion including a plurality of electronic elements, the device comprising: a plurality of first element voltage supply lines connected to a higher potential terminal of the circuit portion; a plurality of second element voltage supply lines connected to a lower potential terminal of the circuit portion; a first trunk voltage supply line connected to each of the plurality of first element voltage supply lines; a second trunk voltage supply line connected to each of the plurality of second element voltage supply lines; a first branch voltage supply line connected to the first trunk voltage supply line to supply a voltage from the outside to the first trunk voltage supply line; a second branch voltage supply line connected to the second trunk voltage supply line to supply a voltage from the outside to the second trunk voltage supply line; a first wiring layer provided above the circuit portion to have the first and second element voltage supply lines and the first and second trunk voltage supply lines placed therein; and at least one upper wiring layer provided above the first wiring layer to have the first and second branch voltage supply lines placed therein.
