Abstract
In a semiconductor device having a first terminal (source terminal) and a second terminal (drain terminal), the substrate main surface of a semiconductor chip is on the ( ) face, the main contact face of an n-type region and a p-type region is the { } face perpendicular to the ( ) face, elongated n-type regions and elongated p-type regions , which are arranged alternately, form a voltage holding area. The first terminal is connected to the p-type regions through wiring, and the second terminal is connected to the n-type regions . Also, the p-type region is formed to cover the bottom comers of a gate polycrystalline silicon layer
