Abstract
A substrate holding hand includes a supporting plate where a circular reference capture range is defined, a plurality of pads disposed within the reference capture range, at least one stationary stopper that is disposed along an outer circumferential circle of the reference capture range, at least one movable stopper having a part at the same height from the supporting plate as the stationary stopper, and a stopper actuator that moves the movable stopper from a retracted position outside the reference capture range to a deployed position closer to the stationary stopper than the retracted position. A circular reduced capture range is defined by the movable stopper at the deployed position, and the front stopper, and a diameter of the reduced capture range is larger than a diameter of the substrate and smaller than a diameter of the reference capture range.
