Abstract:
A portion position calculator calculates positions of first to fifth portions of a substrate on a hand based on detection signals of first to fifth detectors. An imaginary circle calculator calculates four different imaginary circles based on the positions of the first to fourth portions, respectively, to calculate a center position of each imaginary circle. A substrate position determiner calculates a plurality of amounts of deviation among the plurality of center positions. When all of the plurality of amounts of deviation are not more than a threshold value, the substrate position determiner determines a position of the substrate on the hand based on any or all of the four imaginary circles. When at least one of the plurality of amounts of deviation exceeds the threshold value, the substrate position determiner selects an imaginary circle of the four imaginary circles, which passes through the position of the fifth portion, and determines the position of the substrate on the hand based on the selected imaginary circle. A substrate transport operation is controlled based on a result of the determination.

Claim (Index 1):
A substrate transport device that transports a substrate, comprising:\n a movable element; a first driver that moves the movable element; a holder that is configured to hold the substrate; a second driver that moves the holder with respect to the movable element; first, second, third, fourth, and fifth detectors that are provided to detect first, second, third, fourth, and fifth portions different from one another in an outer periphery of the substrate held by the holder; and a transport controller that controls the first and second drivers during transport of the substrate, wherein the transport controller includes a portion position calculator that calculates positions of the first, second, third, fourth, and fifth portions on the holder based on output signals of the first, second, third, fourth, and fifth detectors, respectively, an imaginary circle calculator that calculates four imaginary circles each passing through three of four positions of the first, second, third, and fourth portions calculated by the portion position calculator, a position determiner that determines a position of the substrate on the holder based on the four imaginary circles calculated by the imaginary circle calculator and the position of the fifth portion calculated by the portion position calculator, and a movement controller that controls the first and second drivers based on the position of the substrate determined by the position determiner.
