Claim 0:
1. A cleaning method for removing a silicon-containing film deposited in a temperature-adjustable process container in which temperature is adjusted by a heater and a cooler, the cleaning method comprising:
stabilizing the temperature in the process container to a cleaning temperature; and
removing the silicon-containing film by supplying a cleaning gas into the process container stabilized at the cleaning temperature,
wherein in the removing the silicon-containing film, a heating capability of the heater and a cooling capability of the cooler are controlled based on the temperature in the process container,
wherein the removing the silicon-containing film includes
(a) supplying the cleaning gas into the process container without operating the cooler,
(b) operating the cooler without supplying the cleaning gas into the process container, and
(c) repeating a cycle including (a) and (b),

wherein when the temperature in the process container becomes equal to or higher than a first temperature in (a), (a) transitions to (b), and
wherein the first temperature is changed during the cycle.
