Abstract

This invention prevents a break in a signal wire disposed between wire ends due to attenuation and improves production yields of devices. In a standard cell, a first signal wire extends in a first direction. Second and third signal wires extend in a second direction substantially perpendicular to the first direction and are facing each other across the first signal wire. The second and third signal wires have the widths larger than the width of the first signal wire.
