Abstract: A forming method for an anodized aluminum film on a component for a substrate processing apparatus that subjects a substrate to plasma processing. The forming method includes connecting the component to the anode of a DC power source and immersing the component in a solution consisting mainly of an oxalic acid, and a step of immersing the component in the boiling water for 5 to 10 minutes. The anodized aluminum film grows toward the inside of the component. The amount of expansion and growth of the anodized aluminum film subjected to the semi-sealing process using the boiling water is smaller than the amount of expansion and growth of an anodized aluminum film subjected to a sealing process using water vapor. Further, generation of compressive force due to collision of crystal pillars in the anodized aluminum film is prevented when subjected to the semi-sealing process using the boiling water.

Abstract: A substrate processing apparatus that can prevent particles from being produced through chipping of a film. The film is formed on a surface of a component for the substrate processing apparatus by an anodic oxidization process in which the component is connected to the anode of a direct-current power source and immersed in a solution consisting mainly of an organic acid. The film is subjected to a semi-sealing process using boiling water.

Abstract: A method of resetting a substrate processing apparatus having a chamber which is capable of carrying out abnormality judgment on the substrate processing apparatus accurately without causing a decrease in the utilization ratio of the substrate processing apparatus. The chamber is evacuated. A temperature in the chamber is set. Whether or not there is an abnormality in the chamber is judged. An atmosphere in the chamber is stabilized so as to conform to predetermined processing conditions. At least one selected from data that change in response to a change in a state inside the chamber is measured. The measured data is compared with reference data that corresponds to the measured data for a normal state in the chamber.
