Abstract

In a method of manufacturing a semiconductor device, a gate structure is formed on a substrate. An ion implantation process is performed at an upper portion of the substrate exposed by the gate structure, so that an ion implantation region is formed to have an expanded volume. The ion implantation process uses ions that are identical to a material of the substrate.
