摘要:
A semiconductor integrated circuit device includes a substrate. A gate structure is formed on the substrate and includes a gate insulating film and a gate electrode. A first sidewall spacer is formed on two sidewalls of the gate structure. A second sidewall spacer is formed on the first sidewall spacer. A recess compensation film is interposed between the second sidewall spacer and the substrate. An epitaxial layer is in contact with the recess compensation film.
