Abstract
A method of fabricating a semiconductor device which includes introducing, after a step of patterning a gate electrode, nitrogen atoms into an oxide film covering a device region on a semiconductor substrate, by exposing said oxide film to an atmosphere containing-nitrogen, such that said nitrogen atoms do not reach a region underneath said gate electrode, covering, after said step of introducing nitrogen atoms, said oxide film including said gate electrode by a CVD oxide film continuously without taking out said semiconductor substrate out of a processing chamber and forming a sidewall oxide film on a sidewall surface of said gate electrode by etching back said CVD oxide film.
