Claim 11:
12. A control method comprising:
storing, in a 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;
detecting, by a temperature sensor, a temperature inside the processing container;
extracting an etching rate of the deposited film corresponding to the temperature detected by the temperature sensor from the relationship information stored in the memory in the storing; and
calculating an etching time for removing the deposited film based on the etching rate of the deposited film extracted in the extracting the etching rate and the film thickness information stored in the memory in the storing.
