Abstract:
1. An imaging component position adjustment method 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 substrate position detection apparatus being arranged in a vicinity of a rotatable susceptor on which the substrate is placed and a substrate transferring apparatus that is prepared separately from the susceptor and configured to horizontally drive a supporting pin for transferring the substrate to and/or from the susceptor, the imaging component position adjustment method comprising steps of: supporting a mark-equipped wafer in which a mark is arranged corresponding to the circumferential portion of the substrate at a predetermined height above the susceptor by the supporting pin, 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 calculated in accordance with the plural points.
