Abstract

A semiconductor device is characterized in that source electrode contact regions, each of which is formed of a first conductivity type source layer and a second conductivity type base layer in a surface of a semiconductor surface, are formed at respective intersectional points of a diagonally-arranged lattice, and in that a trench having a gate electrode buried therein is formed so as to snake through the contact regions alternately. By virtue of the structure, the trench arrangement and source/base simultaneous contact quality are improved, to thereby increase a trench density (channel density) per unit area.
