Abstract
Method for fabricating a semiconductor device is disclosed, including the steps of: forming a first resist layer on a substrate; patterning a predetermined region of the first resist layer to form a pattern having a first width which exposes the substrate; forming an insulating film on an entire surface of the substrate including the first resist layer; forming a second resist layer on the insulating film; patterning a predetermined region of the second resist layer to form a pattern over the pattern of the first resist layer having a second width which exposes the insulating film; using the second resist layer as a mask in etching the exposed insulating film to form sidewall spacers at sides of the pattern of the first resist layer; forming a metal layer on an entire resultant surface including the second photoresist layer; and, removing the first and second resist layers and the insulating film to form a T form gate electrode.
