Abstract
In a substrate transportation method, a first movement process is provided for moving a camera to a position above a predetermined region where a peripheral edge of a substrate is supposed to be located in a state where the substrate is lifted by pins protruding beyond a mounting table while a transfer mechanism that has received an instruction for starting an unloading of the substrate mounted on the mounting table is moving to the mounting table. Further, a first image capturing process is provided for controlling the camera moved in the first movement process to capture an image of the predetermined region, and a first detection process is provided for detecting a positional displacement and/or a tilting of the substrate lifted by the pins based on the image captured by the camera in the first image capturing process.
