    • Even in case that a wafer is so greatly deviated that a peripheral portion of the wafer cannot be detected, position determination of the wafer can be performed without inflicting a damage on the wafer. The wafer peripheral portion, which is a target, is detected based on output images from a plurality of imaging units disposed along a peripheral portion shape of the wafer (step S210), and a wafer position deviation correcting step (step S220) or a rough correcting step (step 230) is performed according to the number of the imaging units capable of detecting the wafer peripheral portion. In case that the wafer peripheral portion cannot be detected by all the imaging units, a wafer position adjusting step (step 240) for moving the wafer is performed in a position adjusting direction acquired by a combination of the output images by each imaging unit.

    • A method is disclosed for adjusting an arrangement of coordinates in an imaging area of an imaging component in a substrate imaging plane in a substrate position detection apparatus that detects a position of a substrate in accordance with an image taken of a circumferential portion of the substrate by the imaging component, the apparatus being arranged near a rotatable susceptor on which the substrate is placed and a substrate transferring apparatus prepared separately from the susceptor and configured to horizontally drive a supporting pin for transferring the substrate to and/or from the susceptor. This method includes supporting at a predetermined height above the susceptor by the supporting pin a mark-equipped wafer with a mark arranged corresponding to the circumferential portion of the substrate, bringing the mark into the imaging area, detecting the mark at plural points while horizontally moving the mark in one direction within the imaging area by a predetermined distance by horizontally driving the supporting pin, and calibrating an axis direction of the coordinates in accordance with a direction in which the plural points are arranged; and maintaining the mark-equipped wafer with a height adjustment jig at the predetermined height above the susceptor, bringing the mark into the imaging area, detecting the mark at plural points while moving the mark within the imaging area by a predetermined angle by rotating the susceptor, and calibrating an origin position of the coordinates in accordance with a rotation center obtained in accordance with the plural points.
