Abstract: A method for measuring a substrate is provided. The method comprises irradiating a measurement beam into a site box of an identifiable pattern of a substrate, detecting a center position of the irradiated measurement beam, calculating an amount of shift of the center position of the measurement beam from the center position of the site box, and correcting the center position of the measurement beam to the center position of the site box by compensating the calculated amount of shift.

Abstract: A load port module includes a plate to support at least one substrate, a sensor to detect foreign matter at a predetermined location, and a cleaner to remove the foreign matter at the predetermined location when the foreign matter is detected by the sensor. The cleaner removes the foreign matter at the predetermined location in synchronism with movement of the plate. A mover to move the plate continues to operate after detection of the foreign matter by the sensor and removal of the foreign matter by the cleaner.
