Claim 14:
15. A non-transitory computer-readable recording medium storing a program that causes, by a computer, a substrate processing apparatus to perform:
(a) supplying a process gas into a process chamber via a process gas supply pipe connected thereto with a substrate accommodated in the process chamber and exhausting the process gas from the process chamber via an exhaust pipe connected thereto;
(b) detecting a first concentration which is a concentration of the process gas in the process gas supply pipe or a second concentration which is a concentration of the process gas contained in an exhaust gas in the exhaust pipe; and
(c) controlling a process gas supply system to reduce a predetermined flow rate into the process chamber or to stop a supply of the process gas into the process chamber when an amount of the process gas consumed in the process chamber, which is calculated based on a value of the first concentration and a value of the second concentration detected by a gas concentration sensor, becomes equal to or lower than a predetermined value.
