Provided is a transport method comprising judging whether there is a possibility that misalignment greater than or equal to a threshold value occurs between substrates to be layered that are held by a pair of substrate holders aligned and stacked by an aligning section, the misalignment occurring when the pair of substrate holders is transported from the aligning section to a pressure applying section; and if the judgment indicates that there is the possibility of misalignment, transporting the pair of substrate holders to a region other than the pressure applying section. Whether there is the possibility of misalignment may be judged based on acceleration of the substrate holders. Whether there is the possibility of misalignment may be judged based on acceleration of a transporting section that transports the substrate holders. Whether there is the possibility of misalignment may be judged based on relative positions of the substrate holders. Whether there is the possibility of misalignment may be judged based on relative positions of (i) a transporting section that transports the pair of substrate holders and (ii) one of the pair of substrate holders.
A transport method comprising:
A transport apparatus that transports a pair of substrate holders, which are aligned and stacked by an aligning section and hold substrates to be layered, from the aligning section to a pressure applying section, comprising:
