Abstract
The present invention provides a technology capable of removing impurities remaining in a thin film when the film is formed and modifying a characteristic of the thin film according to a change in impurity concentration. There is provided a method of manufacturing a semiconductor device including: (a) repetitively supplying a plurality of gases including elements constituting a film in temporally separated pulses (in non-simultaneous manner) to form the film on the substrate; and (b) exciting a modifying gas including a reducing gas and at least one of a nitriding gas and an oxidizing gas by plasma and supplying the modifying gas excited by plasma to modify the film.
