The present invention relates to an internal chamber processing method, and more particularly, to an internal chamber processing method for performing processing on a chamber and a component inside the chamber. Disclosed is an internal chamber processing method for processing the inside of a chamber in which substrate processing is performed, the method including a pressurizing operation (S) of raising a pressure inside a chamber to a first pressure (P) higher than the atmospheric pressure by using a pressurized gas and a depressurizing operation of lowering the pressure inside the chamber from the first pressure (P) to a second pressure (P) after the pressurizing operation (S). The pressurizing operation (S) and the depressurizing operation (S) are performed in a state in which a substrate to be processed is removed from the inside of the chamber.

Internal chamber processing method and substrate processing method

Disclosed is a substrate processing method including: a pressurizing operation of raising a process pressure from a first pressure (P) to a second pressure (P) that is greater than the atmospheric pressure; a depressurizing operation of lowering the process pressure from a sixth pressure (P), which is greater than the atmospheric pressure, to a seventh pressure (P); and an annealing operation of changing the process pressure into a preset pressure change pattern between the pressurizing operation and the depressurizing operation, under a temperature atmosphere of a second temperature (T) higher than the room temperature. A temperature raising operation of raising a temperature atmosphere from a first temperature (T) to the second temperature (T) is performed from a preset temperature raising start point (t) to a preset temperature raising end point (t) while the pressurizing operation is performed or after the pressurizing operation is performed.
