Abstract
A semiconductor integrated circuit includes: implanting impurity ions of a p-type at different implantation positions by multiple implantation in a part of an upper portion of a semiconductor layer of an n-type to form first ion implantation regions; implanting the impurity ions of the p-type at different implantation positions by multiple implantation in another part of the upper portion of the semiconductor layer to form second ion implantation regions; activating the impurity ions in the first ion implantation regions to form a well region, and activating the impurity ions in the second ion implantation regions to form a body region; forming a control element including first and second terminal regions of the n-type in an upper portion of the well region; and forming an output-stage element including an output terminal region of the n-type in an upper portion of the body region to be controlled by the control element.
