Beschreibung
Zusammenfassung:	There is provided a cleaning technique that includes supplying a hydrogen fluoride gas into a process vessel, in which a process of forming an oxide film containing at least one of carbon and nitrogen on a substrate has been performed, to remove a deposit containing at least one of carbon and nitrogen adhered to an interior of the process vessel, wherein the act of supplying the hydrogen fluoride gas is performed under a condition in which an etching rate of the deposit adhered to the interior of the process vessel is higher than an etching rate of a quartz member in the process vessel.
