Abstract
A method and apparatus for transferring a substrate is provided. In one embodiment, an apparatus for transferring a substrate includes at least one end effector. A disk is rotatably coupled to the end effector. The disk is adapted to rotate the substrate relative to the end effector. The end effector may additionally include a sensor coupled thereto. The sensor is adapted to detect an indicia of orientation of the substrate supported by the end effector. In another embodiment, a method for transferring a substrate includes rotating the substrate disposed on an end effector and detecting an indicia of orientation of the substrate.
