Patent ID: 8744615

Claim:
A substrate processing system configured to bring out substrates from a container in which a plurality of accommodating portions each of which can accommodate one substrate are arranged in an up and down direction, to process the substrates, and to return the processed substrates to the container, the substrate processing system comprising: a processing part configured to process the substrates; and a substrate detecting apparatus configured to detect whether the substrates are respectively accommodated in the respective accommodating portions of the container or not; wherein the substrate detecting apparatus detects, before the substrates are processed by the processing part, whether the substrates are respectively accommodated in the respective accommodating portions of the container or not, and detects accommodated conditions of the respective substrates accommodated in the respective accommodating portions, and wherein the substrate detecting apparatus detects, after the substrates have been processed by the processing part, whether the substrates are respectively accommodated in the respective accommodating portions of the container or not.
