Abstract

There is provided a method of manufacturing a semiconductor device including: preparing a semiconductor substrate having an active region; forming a dielectric layer for gate insulation on the active region; forming a curing layer with a material containing germanium (Ge) on the dielectric layer; heat-treating the curing layer; and removing the curing layer. The germanium-containing material may be silicon germanium (SiGe) or germanium (Ge).
