  • Publication number: 20140023776
    Abstract: A substrate is transported based on coordinates information indicating a receiving position of the substrate and a placement position of the substrate by a hand. If the substrate is shifted from a first position, the substrate is received by the hand while a center of the substrate is shifted from a normal position of the hand. The hand that holds the substrate is moved toward a second position. A plurality of portions at an outer periphery of the substrate are detected before the substrate is placed. A shift of the substrate with respect to the normal position of the hand is detected based on the detection result, and the coordinates information is corrected such that a shift between a position of the center of the substrate to be placed at the second position by the hand and the center of the second position is canceled.
