Abstract:
1. A method of fabricating a dielectric layer, the method comprising the steps of: providing a semiconductor substrate which has been washed; forming a first nitride film by loading the semiconductor substrate in a first furnace and subjecting the semiconductor substrate to a first nitride treatment; forming a first oxide film by unloading the semiconductor substrate having the first nitride film out of the first furnace and subjecting the semiconductor substrate to a first nitride treatment by introducing air while the semiconductor substrate is unloaded; forming a second nitride film by loading the semiconductor substrate having the first oxide film in a second furnace and subjecting the semiconductor substrate to a second nitride treatment; and forming a second oxide film by subjecting a top surface of the second nitride film to a second oxide treatment.
