Abstract
It is intended to provide a semiconductor device including a MOS transistor, comprising: a semiconductor pillar; a bottom doped region formed in contact with a lower part of the semiconductor pillar; a first gate formed around a sidewall of the semiconductor pillar through a first dielectric film therebetween; and a top doped region formed so as to at least partially overlap a top surface of the semiconductor pillar, wherein the top doped region has a top surface having an area greater than that of the top surface of the semiconductor pillar.
