Abstract
A plasma process method of processing an object to be processed by a plasma process while enabling cooling of an inside of a plasma apparatus by taking in and exhausting a gas to evacuate an atmosphere of the inside includes measuring a temperature of the atmosphere of the inside of the plasma process apparatus while the plasma is not generated; and stopping taking the gas into the inside of the plasma process apparatus during the plasma process in a case where the measured temperature is lower than a first preset threshold temperature when the atmosphere is evacuated at a preset volumetric flow rate.
