Abstract
A method of manufacturing semiconductor devices. A gate structure is formed over a substrate. A dopant implantation is carried out to form a lightly doped region in the substrate on each side of the gate structure. An insulation layer is formed over the substrate. A portion of the insulation is later removed so that a portion of the insulation layer is retained over the substrate on each side of the gate structure. A spacer is formed on each sidewall of the gate structure. Another ion implantation is carried out such that the dopants penetrate through the insulation layer on the substrate on each side of the gate structure to form a heavily doped region in the substrate.
