Claim Text:
1. A substrate processing system that loads and unloads substrates through the use of a transport container accommodating and supporting the substrates in multiple stages, the transport container including an opening portion for inserting the substrates and an opening/closing door for opening or closing the opening portion, the system comprising: a mounting unit on which the transport container is mounted; an opening/closing device configured to hold the opening/closing door of the transport container mounted on the mounting unit to open or close the opening/closing door; a mapping device configured to perform a mapping operation while the opening/closing door is kept open, the mapping operation including detecting and acquiring a position of each of the substrates accommodated within the transport container as substrate position information; and a first control unit configured to control the opening/closing device and the mapping device, wherein the first control unit determines, based on the substrate position information detected by the mapping device, whether the substrate position is in a normal state or in an abnormal state, wherein if the substrate position is in the abnormal state, the first control unit controls the opening/closing device to perform a closing/opening operation by which the opening/closing door is closed and then opened to correct the substrate position in the abnormal state, and thereafter, controls the mapping device to perform a next mapping operation, wherein the first control unit controls the opening/closing device and the mapping device to repeat the closing/opening operation and the next mapping operation, and wherein if the substrate position detected by the next mapping operation is in the normal state, the first control unit controls the opening/closing device and the mapping device to stop the closing/opening operation and the next mapping operation.
