Claim 0:
1. A method of processing a substrate, comprising:
forming a film containing a metal element and nitrogen on the substrate by performing a cycle a predetermined number of times, the cycle including performing:
(a) supplying a first gas containing the metal element and a halogen element and a second gas containing silicon and hydrogen to the substrate so that supply periods of the first gas and the second gas at least partially overlap with each other while a space where the substrate exists is exhausted;
(b) supplying a reaction gas containing nitrogen and different from the first gas and the second gas to the substrate without exposing the substrate to the first gas and the second gas, such that there is no overlap between the reaction gas being introduced and the first gas and the second gas being introduced; and
(c) between (a) and (b), purging the space where the substrate exists without supplying the first gas, the second gas and the reaction gas to the substrate.
