    Abstract: PROBLEM TO BE SOLVED: To provide a lithographic apparatus which decreases disturbance of a projection system due to the scanning power of a movable object.
    SOLUTION: The lithographic apparatus includes: an illumination system configured to condition a radiation beam; a patterning device support constructed to support a patterning device capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table WT constructed to hold a substrate; a projection system PS configured to project the patterned radiation beam onto a target portion of the substrate; an active air mount AM supporting the projection system PS and including at least one actuator; and a feed-forward device FD configured to provide a feed-forward signal to the at least one actuator on the basis of a set-point signal of a movable object, wherein the feed-forward signal is designed to decrease a disturbance effect on the projection system PS due to movement of the movable object.

    Abstract: PROBLEM TO BE SOLVED: To provide a positioning system improved in position accuracy, and also to provide lithographic equipment reduced in overlay error and/or problem with image formation. SOLUTION: The lithographic equipment includes a positioner which positions the first section of the equipment relative to the second position of the equipment, the positioner includes a motor having a motor constant which depends on a motor position which defines the relationship between a motor input and a motor output, and a control system which drives the motor, the control system includes a set point generator which provides a reference signal based on a desired position of the first section relative to the second position, and a controller which provides a drive signal to the motor based on the reference signal, and the controller includes a compensator which at least partially compensates the drive signal for the motor constant depending on a motor position. The present invention relates to a positioner, a method for optimizing the positioning system, and a method for deriving a motor constant depending on a motor position. COPYRIGHT: (C)2010,JPO&INPIT
