Abstract
A semiconductor device has a semiconductor circuit provided on a semiconductor substrate. The semiconductor circuit has a source, a drain, a gate and a wiring connected to one of the source, the drain and the gate. Conductors for electrostatic discharge protection are connected to one of a ground line and a power supply line and are disposed over a region of the semiconductor circuit not occupied by the wiring. A ratio of a total area of the conductors disposed over the semiconductor circuit to an area of a chip occupied by the semiconductor circuit is 40% or more.
