Patent ID: 8110852

Claim:
A semiconductor integrated circuit device, provided on an SOI substrate and comprising: an input/output circuit section; and a core circuit section, which is provided more internally than said input/output circuit section and operates at a lower power supply voltage than said input/output circuit section, wherein said input/output circuit section has a first MOS transistor of a first conductivity type, said core circuit section has a second MOS transistor of said first conductivity type, a first finger length of a first gate electrode of said first MOS transistor, which is defined by a gate electrode extending direction length of a portion on an active region, is set shorter than a second finger length of a second gate electrode of said second MOS transistor, which is defined by a gate electrode extending direction length of a portion on an active region, and said first and second MOS transistors include transistors having body regions under said first and second gate electrodes electrically connected to body contact regions provided on the outside of both ends of said first and second gate electrodes in the gate width direction within the surface of said SOI substrate, wherein said body contact regions being positioned apart from respective active regions.
