    Abstract: A precision assembly (210) for positioning a device (226) includes a stage (260) that retains the device (226), a dual mover assembly (228) that moves the stage (260), and the device (226) along a movement axis (266), a measurement system (222) and a control system (224). The dual mover assembly (228) includes a first mover (262) that moves the stage (260) along the movement axis (266) and a second mover (264) that moves the device (226) along the movement axis (266). The second mover (264) is rigidly coupled to the first mover (262) so that movement of the first mover (262) results in movement of the second mover (264). Further, the total output of the dual mover assembly (228) along the movement axis (266) is equal to the sum of the movement of the first mover (262) and the movement of the second mover (264). The measurement system (222) measures a movement position along the movement axis (266). The control system (224) controls the dual mover assembly (228) utilizing the movement position. The control system (224) is designed to effectively decouple the control of the first mover (262) from the control of the second mover (264). Further, the control system (224) includes a quantization feedforward loop.

    Abstract: A positioning method in which a system performs operations relative to areas on a substrate by a series of relative movements between the system and substrate scanning exposures. The method includes the steps of disposing a first area relative to a system performing an operation relative to the first area, and moving the substrate from a first position where the first operation relative to the first area has finished to a second position where a second operation relative to a second area is to start, and synchronously moving the system from a third position where the first operation relative to the first area has finished to a fourth position where the second operation relative to the second area is to start. An acceleration of the substrate during movement from the first position to the second position and an acceleration of the system during movement from the third position to the fourth position continually have absolute values greater than zero.
