Claim Text:
1. A semiconductor device manufacturing method comprising: (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 source gas before the adsorption of the source gas on the substrate is saturated to suppress the adsorption of the source gas on 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 comprising 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.
