Patent ID: 7737473

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