Abstract: A device includes a substrate holding unit 25 configured to hold a substrate and be movable in a transversal direction to transfer the substrate from one module to another module; a first detecting unit 3 configured to detect a position of the substrate on the substrate holding unit 25 before the substrate holding unit 25 transfers the substrate into the another module after receiving the substrate from the one module; second detecting units 55 and 56 configured to detect a position deviation between a position of the substrate holding unit 25, which is located at a temporary position set to transfer the substrate into the another module, and the temporary position; and a position determining unit 10 configured to determine a transfer position where the substrate is transferred into the another module based on the position of the substrate on the substrate holding unit 25 and the position deviation.
