Patent ID: 7605059

Claim:
A semiconductor device comprising: a MOS transistor including: a semiconductor substrate; a source region, formed in the semiconductor substrate, that comprises an impurity of a first conductive type; a drain region, formed in the semiconductor substrate, that comprises an impurity of the first conductive type; and a gate electrode, formed through a gate insulating film on the semiconductor substrate, between the source region and the drain region; an impurity region of the first conductive type formed in the semiconductor substrate; an impurity region of a second conductive type opposite the first conductive type formed in the semiconductor substrate; a first wiring connecting the gate electrode to the impurity region of the first conductive type; a second wiring connecting the first wiring to the impurity region of the second conductive type; a first wiring disconnecting terminal for disconnecting the first wiring; and a second wiring disconnecting terminal for disconnecting the second wiring.
