Abstract: A cleaning method includes: supplying a cleaning gas in a processing container while continuously increasing a pressure in the processing container in a stepwise manner at a plurality of time points, thereby executing a cleaning of the processing container by removing a film deposited in the processing container; and detecting an end point of the cleaning based on time-dependent data of a concentration of a predetermined gas generated during the executing the cleaning, for each pressure of the plurality of time points. The executing the cleaning is implemented when the time-dependent data of the concentration of the predetermined gas generated in the continuously increasing the pressure changes from an increasing state to a decreasing state after exceeding a threshold value.

Abstract: A processing apparatus includes: a processing container; a temperature sensor that detects a temperature therein; a gas supply unit that supplies a cleaning gas into the processing container; a pressure regulation unit that regulates a pressure in the processing container; and a control unit that controls the gas supply unit and the pressure regulation unit to perform a cleaning processing of removing a deposited film in the processing container. The control unit stores a vapor pressure curve in which the temperature in the processing container is associated with a vapor pressure of water in the processing container. In the cleaning processing, the control unit sets a target pressure below the vapor pressure curve based on the temperature detected by the temperature sensor and the vapor pressure curve, and controls the pressure regulation unit such that the pressure in the processing container becomes the target pressure.

Abstract: A deposition method according to one aspect of the present disclosure includes performing multiple execution cycles serially. Each of the multiple execution cycles includes: supplying a raw material gas into a process chamber; and supplying a reactant gas that reacts with the raw material gas. Among the multiple execution cycles, at least one execution cycle includes adjusting a pressure in the process chamber without supplying the raw material gas, and the adjusting of the pressure is performed prior to the supplying of the raw material gas.
