Patent ID: 7279749

Claim:
A semiconductor device, comprising in a field region: a gate; a gate insulating film disposed right under the gate; a body region disposed right under the gate insulating film; and source and drain regions formed on both sides of the body region, the gate comprising a first section extending on the field region along the channel width direction, and a pair of second sections formed on both ends of the first section in the channel width direction and extending along the channel length direction, and is formed as an H-type gate in plan view, and a part of each of the pair of second sections of the H-type gate being formed on the field region having a constant length in the channel length direction to define the channel width by the length of the first section in the channel width direction; and the constant length in the channel length direction of the field region being shorter than a length in the channel length direction of the field region of a portion of the first section.
