Patent ID: 8382088

Claim:
A substrate processing apparatus for bringing a substrate out from a carrier placed on a transfer port, by a substrate transfer portion inside a transfer chamber, into a processing module in order to perform a substrate process in the processing module, the substrate processing apparatus comprising: a substrate storing chamber coupled to an exterior of the transfer chamber via a transfer opening in order to be in communication with the transfer chamber; a first storage that is provided in the substrate storing chamber and includes plural substrate holding members that hold corresponding one of plural substrates thereby to store the plural substrates for a first storing purpose; a second storage that is provided in the substrate storing chamber and includes plural substrate holding members that hold corresponding one of plural substrates thereby to store the plural substrates for a second storing purpose different from the first storing purpose; and a shifting mechanism that shifts the first storage and the second storage in order to position a substrate storing area of one of the first storage and the second storage so that substrate transferring is enabled between the substrate storing area and the substrate transfer portion via the transfer opening.
