Claim:
1. A substrate processing apparatus that removes substrates from a transport container and processes the substrates, wherein the transport container has a container main body whose substrate removal opening formed in a front face of the container main body is air-tightly closed by a lid, and the transport container is configured to allow a plurality of the substrates to be transported while the substrates being contained in the transport container in a form like shelves, said substrate processing apparatus comprising: a load port into which the transport container is carried; a detecting unit that detects spatial positions of the substrates contained in the transport container, which has been carried into the load port and the lid of which has been removed; a processing unit that processes the substrates removed from the transport container having been carried into the load port; and a control unit that performs a first step that detects spatial positions of the substrates contained in the transport container, which are in the transport container having been carried into the load port, before the substrates are removed from the transport container to be delivered to the processing unit; a second step that detects spatial positions of the substrates contained in the transport container, which have been processed in the processing unit and returned to the original transport container, before closing the lid; and a third step that judges whether or not the transport container has an abnormality based on results of the first and second steps.
