    摘要: An actuator system is disclosed having a first actuator (XP1) and a second actuator (XP2) configured to control a relative position of optical components of a lithographic apparatus. The first actuator (XP1) is configured to provide a displacement, parallel to an actuation direction, between a mounting point of a first component of the lithographic apparatus and a second component of the lithographic apparatus. The second actuator (XP2) is configured to provide a displacement parallel to the actuation direction between a reference mass (M1) associated with the second actuator (XP2) and the mounting point of the first component of the lithographic apparatus. The second actuator (XP2) may be driven such that the displacement between the second actuator (XP2) and the reference mass (M1) increases the apparent stiffness of the first actuator (XP1).

    摘要: A lithographic apparatus including a projection system configured to project a patterned radiation beam onto a target portion of a substrate; a metrology frame supported by a vibration isolation support device; an object movable with respect to the metrology frame; and a displacement determining unit to determine positions, speeds and/or accelerations of the object with respect to the metrology frame and/or the projection system. At least one actuator is provided for applying correcting forces and/or torques on the metrology frame, and a controller is provided which is configured to calculate the correcting forces and/or torques to be applied to the metrology frame based on the determined positions, speeds and/or accelerations of the object in order to compensate for pressure pulses exerted on the metrology frame due to movements of the object with respect to the metrology frame.

    摘要: An optical component of the lithographic apparatus is moved. A substrate support is moved so as to be synchronous with the motion of the optical component. A momentary position of the optical component is measured. A momentary position of the substrate support is measured at a first sampling rate. The measured momentary position of the optical component is compared with a desired momentary position of the optical component to generate an optical component position error signal in accordance with a difference between the two optical component positions. The measured momentary position of the substrate support is compared with a desired momentary position of the substrate support to generate a substrate support position error signal in accordance with a difference between the two substrate support positions. The momentary position of the optical component is adjusted so as to compensate for the difference between the two substrate support positions.
