Document Type and Number:
WIPO Patent Application WO/2024/084853
Kind Code:
A1
Abstract:
The present description discloses techniques for highly accurately determining the position of a substrate. This position determination method comprises: a step for setting a region including an end portion of a substrate in a reference image as a reference region, and detecting a pixel position of the end portion of the substrate in the reference region as a reference pixel position; a step for setting a region including the end portion of the substrate in a comparison image as a comparison region, and detecting the pixel position of the end portion of the substrate in the comparison region as a comparison pixel position; and a step for determining whether the difference between the reference pixel position and the comparison pixel position is greater than a predetermined threshold value.
