Claim 15:
16. A substrate processing apparatus, comprising:
a process chamber configured to accommodate a substrate;
a gas supply system configured to supply a first gas containing a metal element and a halogen element, a second gas containing silicon and hydrogen, and a reaction gas containing nitrogen and different from the first gas and the second gas to the substrate accommodated inside the process chamber; and
a controller configured to control the gas supply system so as to form a film containing the metal element and nitrogen on the substrate by performing a cycle a predetermined number of times, the cycle including performing:
(a) supplying the first gas and the second gas to the substrate accommodated inside the process chamber so that supply periods of the first gas and the second gas at least partially overlap with each other while exhausting an inside of the process chamber;
(b) supplying the reaction gas to the substrate without exposing the substrate to the first gas and the second gas; and
(c) between (a) and (b), purging the process chamber where the substrate is accommodated without supplying the first gas, the second gas and the reaction gas to the substrate.
