Claim Text:
1. A method of manufacturing a semiconductor device, comprising: supplying a halogen-containing metal material containing a metal element and a halogen element to a substrate while supplying an inert gas; supplying a reactant gas containing a nitrogen element to the substrate while supplying the inert gas at a flow rate larger than a flow rate of the inert gas supplied during the supplying of the halogen-containing metal material; forming a metal-containing nitride film on the substrate by performing a cycle a predetermined number of times, the cycle including: supplying the halogen-containing metal material; removing the halogen-containing metal material; supplying the reactant gas; and removing the reactant gas, wherein a flow rate of the inert gas supplied during the supplying of the reactant gas is larger than a flow rate of the inert gas supplied during the supplying of the halogen-containing metal material, a flow rate of the inert gas supplied during the removing of the halogen-containing metal material, and a flow rate of the inert gas supplied during the removing of the reactant gas.
