Abstract:
1. A method of manufacturing a semiconductor device, comprising: (a) forming a first film containing a metal element on a substrate by performing a cycle a predetermined number of times, the cycle including: (a-1) supplying a first precursor gas being a fluorine-free inorganic gas containing the metal element to the substrate; and (a-2) supplying a first reactant gas having reducibility to the substrate; (b) forming a second film containing the metal element on the first film by performing a cycle a predetermined number of times, the cycle including: (b-1) supplying a second precursor gas containing the metal element and fluorine to the substrate; and (b-2) supplying a second reactant gas having reducibility to the substrate; and (c) forming a film containing the metal element and obtained by the first film and the second film being laminated on the substrate by performing the (a) and (b).
