Claim 0:
1. A control device comprising:
a memory; and
a processor coupled to the memory and configured to:
store, in the memory, relationship information indicating a corresponding relationship between a temperature inside a processing container of a processing apparatus that performs a processing on a substrate accommodated therein 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, by a temperature sensor, a temperature inside the processing container;
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.
