Abstract:
A method of manufacturing a semiconductor device of the present invention is a method of manufacturing a semiconductor device that is provided with a step of successively forming a gate insulating film and a gate electrode on a semiconductor substrate and a step of forming a silicon nitride film that covers at least the gate insulating film and the side portions of the gate electrode, in which the silicon nitride film is formed by laminating a plurality of silicon nitride layers by repeating a step of forming a silicon nitride layer of a predetermined thickness by the low-pressure chemical vapor deposition method and a step of exposing the silicon nitride layer to nitrogen.
