Patent ID: 6952027

Claim:
A semiconductor integrated circuit device comprising: a semiconductor region of a first conductivity type; a first insulated-gate field effect transistor formed on the semiconductor region of the first conductivity type and having a source/drain region of a second conductivity type connected to an output terminal; a semiconductor region of the second conductivity type formed adjacent to the source/drain region on the semiconductor region of the first conductivity type and connected to a gate of the first insulated-gate field effect transistor; and a second insulated-gate field effect transistor formed on the semiconductor region of the first conductivity type and having a source/grain region of the second conductivity type connected to the gate of the first insulated-gate field effect transistor to drive the first insulated-gate field effect transistor, wherein a distance from the source/drain region of the first insulated-gate field effect transistor to the semiconductor region of the second conductivity type is shorter than a distance from the source/drain region of the first insulated-gate field effect transistor to the source/drain region of the second insulated-gate field effect transistor.
