Classification: CPC H  C | IPC C  H

Claim 9:
10. A processing apparatus comprising:
a processing container configured to accommodate a substrate;
a temperature sensor configured to detect a temperature inside the processing container; and
a control device, wherein the control device is programmed to:
store, in a memory, relationship information indicating a corresponding relationship between a temperature inside the processing container and an etching rate of a deposited film inside the processing container, and film thickness information including a cumulative film thickness of the deposited film, detect a temperature inside the processing container by the temperature sensor, extract an etching rate of the deposited film corresponding to the temperature detected by the temperature sensor from the relationship information stored in the memory, calculate an etching time for removing the deposited film based on the extracted etching rate of the deposited film and the film thickness information stored in the memory, and execute a cleaning process of the processing apparatus by controlling an operation of the processing apparatus to remove the deposited film inside the processing container based on the etching time.
