PURPOSE:To operate an integrated circuit normally even when wiring width is reduced by dividing a circuit terminal into a plurality of groups by the voltage- drop tolerance values of wirings to reference voltage and separately mounting the power supply wirings at every group. CONSTITUTION:A circuit terminal 2 having the small voltage-drop tolerance values of wirings on an integrated circuit to voltage as a reference and a large circuit terminal 3 are divided, and power supply wirings 4' and 4'' are each connected to a power supply pad 7. Currents i1 and i2 each flow into the terminal 2 and the terminal 3, and currents i1+i2+i3 flow out at a wiring terminal 5'. Accordingly, voltage drop can be reduced by using the wirings 4' and 4'', and wiring width can be minimized remarkably. |
