Abstract

Provided is a high driving performance horizontal MOS wherein a gate width per unit area is increased by forming a plurality of trenches parallel to the gate length direction to improve current driving performance of a transistor. Furthermore, a trench pattern is laid out to permit all the semiconductor surfaces of a trench uneven section to be {100} crystalline faces, and to permit all the gate surfaces to be {100} crystalline faces.
