Abstract
Provided is a semiconductor device manufacturing method including: (a) supplying a source gas containing a first element and chlorine to a substrate accommodated in a processing chamber to form an adsorption layer of the source gas on the substrate; (b) supplying a chlorine-containing gas having a composition different from that of the source gas to the substrate while supplying the sources gas before an adsorption of the source gas to the substrate is saturated to suppress the adsorption of the source gas to the substrate; (c) removing the source gas and the chlorine-containing gas remaining on the substrate; (d) supplying a modifying gas including a second element to the substrate to form a layer including the first element and the second element on the substrate by modifying the adsorption layer of the source gas; and (e) removing the modifying gas remaining on the substrate.
