Abstract:
1. A transport apparatus that supports and moves a substrate by using a robot hand between a plurality of chambers, the transport apparatus comprising: a first detection unit that detects the substrate, in a first stop position of the robot hand, using a first detection position set on one surface of the substrate supported by the robot hand; and a second detection unit that detects the substrate, in a second stop position of the robot hand, using a second detection position set on the one surface of the substrate supported by the robot hand; wherein the substrate is a disk-shaped wafer, the first detection position and the second detection position are set concentrically on the one surface of the substrate; and wherein the first detection position is constituted by two detection points that separate from each other and the second detection position is constituted by one detection point that positions at an opposite side of the substrate when seen from an intermediate point of a virtual line connecting the two detection points constituting the first detection position.
