Claim:
1. A substrate processing apparatus comprising: a processing vessel configured to process a substrate; a substrate container transfer stand configured to transfer a substrate container accommodating the substrate into and out of a transfer chamber; a substrate container opening/closing part configured to open and close a cover of the substrate container; a substrate container storing shelf configured to store the substrate container; a first purging part controlled by a first controller to perform a first purge to supply inert gas at a first flow rate into the substrate container mounted on the substrate container transfer stand or the substrate container opening/closing part, wherein the first purging part is installed in at least one of the substrate container transfer stand and the substrate container opening/closing part; and a second purging part controlled by a second controller to perform a second purge to supply inert gas at a second flow rate into the substrate container mounted on the substrate container storing shelf, the second flow rate being lower than the first flow rate, wherein the second purging part is installed in the substrate container storing shelf.
