Abstract
A semiconductor device includes: a first semiconductor layer formed at a surface of a semiconductor substrate; an insulating layer formed on the surface of the semiconductor substrate; a first electrode that is electrically connected to the first semiconductor layer; a second semiconductor layer formed to a surface of a region, which is adjacent to the first semiconductor layer; a second electrode formed above a part of the second semiconductor layer; a third semiconductor layer adjacent to the second semiconductor layer in the one direction; a fourth semiconductor layer formed to a surface of a region, which is adjacent to the third semiconductor layer in the one direction; a third electrode that is electrically connected to the fourth semiconductor layer; and a conductor that is separated from the second electrode in the one direction and is kept at the same potential as the first electrode.
