Classification: CPC C | IPC C

Claim 7:
8. A processing apparatus for depositing a silicon-containing film, the processing apparatus comprising:
a process container;
a gas supply section configured to supply a cleaning gas into the process container;
a heater configured to heat an interior of the process container;
a cooler configured to cool the interior of the process container;
a temperature sensor configured to detect a temperature in the process container; and
a controller,
wherein the controller is configured to execute
stabilizing the temperature in the process container to a cleaning temperature; and
removing the silicon-containing film by supplying the cleaning gas from the gas supply section into the process container stabilized at the cleaning temperature,
wherein in the removing the silicon-containing film, the controller is configured to control a heating capability of the heater and a cooling capability of the cooler based on the temperature detected by the temperature sensor,

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.
