发明名称 METHOD FOR FABRICATING A SEMICONDUCTOR DEVICE
摘要 A method for fabricating a semiconductor device includes: forming a dummy gate that defines a region in which a gate electrode should be formed on a semiconductor substrate; forming a surface film on the semiconductor substrate by directional sputtering vertical to a surface of the semiconductor substrate, the directional sputtering being one of collimate sputtering, long throw sputtering and ion beam sputtering; removing the surface film formed along a sidewall of the dummy gate; removing the dummy gate; and forming the gate electrode in the region from which the dummy gate on the semiconductor substrate has been removed.
