Abstract
A method of controlling a substrate processing apparatus that includes a stage, an annular member, a gas introduction mechanism, an exhaust part and a heat transfer gas introduction supply/exhaust part, the method including: mounting a substrate on the stage, and mounting the annular member on the substrate to press the substrate; creating a pressure of a heat transfer gas to be supplied into a space formed between a rear surface of the substrate and a front surface of the stage using the heat transfer gas supply/exhaust part; supplying the heat transfer gas into the space from the heat transfer gas supply/exhaust part; introducing the gas from the gas introduction mechanism into a container; exhausting the heat transfer gas from the space through an orifice; subsequently, exhausting the heat transfer gas from the space; and removing the annular member from the substrate.
