Abstract
PURPOSE:To constitute a three-dimensional off set, and enable the high density integration and the high breakdown voltage operation, by arranging a trench between the gate region and the drain region on an Si substrate, and making the bottom and a part of the side-wall along the trench as off-set part. CONSTITUTION:An off-set part 6 is constituted of an impurity diffusion layer being an N<-> diffusion layer aII over the side-wall and the bottom part of a trench 7. On an Si substrate 1, an N<+> drain region 2 is arranged on the opposite side of the trench 7 to a gate electrode 5, and a transistor is formed whose off set length is longer than the plane size. Therefore a transistor having an off-set whose effective length is longer than the usual length although a plane off-set length is short, is obtained. As a result, the distance between gate and drain becomes short, so that the high density integration and the high breakdown voltage operation are enabled.
