摘要: The invention provides a pneumatic support device for a lithographic apparatus and a lithographic apparatus with such support device. The support device comprises a gas spring. The gas spring comprises a suspending part, a suspended part, and a pressure chamber configured for supporting the suspended part relative to the suspending part. The support device further comprises an actuator configured for positioning the suspended part relative to the suspending part, an acceleration sensor configured for generating a first sensor signal representative for the acceleration of the suspending part, a pressure sensor configured for generating a second sensor signal representative for the pressure in the pressure chamber, and a control unit. The control unit is configured to: receive the first sensor signal, receive the second sensor signal, filter the first sensor signal in a low-pass filter, filter the second sensor signal in a high-pass filter, determine, based on the filtered first sensor signal and filtered second sensor signal, a force exerted by the suspending part on the suspended part, and generate, based on said force, a control signal for the actuator.

摘要: The present invention relates to a positioning system, including: a first actuator to exert an actuation force on a moveable body, the first actuator being coupled to a balance mass configured to absorb a reaction force resulting from the actuation force, the actuation force providing an acceleration of the moveable body and the reaction force providing an acceleration of the balance mass, wherein a force resulting from the acceleration of the moveable body together with a force resulting from the acceleration of the balance mass result in a balance mass torque; a balance mass support to support the balance mass onto a frame, which balance mass support engages the frame at a support position; and a torque compensator; wherein the torque compensator exerts a compensation force to compensate the balance mass torque, and wherein the torque compensator exerts the compensation force on the frame at the support position.

摘要: A lithographic apparatus has: a conduit through which a gas can flow; a gas mover configured to cause the gas to flow in the conduit; a wall in contact with the gas in the conduit and defining a membrane aperture therein; and an acoustic filter including a flexible membrane fixed in the membrane aperture. The acoustic filter reduces transmission of acoustic disturbances without adding any flow resistance.

摘要: A lithographic apparatus has a compartment which accommodates a movable object. Movements of the movable object cause acoustic disturbances in the compartment. An acoustic damper is arranged to damp the acoustic disturbances in the compartment and comprises a chamber (100) in communication with the compartment and a perforated plate (101), having a plurality of through-holes (102), between the chamber and the compartment.
