    摘要: A method for damping an object in two or more degrees of freedom, including measuring a position quantity at each of the two or more measurement locations; extracting from the measured position quantities a measurement signal for each dynamic mode; feeding the measurement signal of a dynamic mode to a controller unit associated with the respective dynamic mode, the controller unit providing for each dynamic mode an output signal on the basis of the respective measurement signal; and providing a control signal to each of the two or more actuators, the control signal for each actuator being based on output signals of one or more controller units.

    摘要: A lithographic apparatus has a mechanism with a movable element, at least partially made from a magnetizable material. The movable element is movable between a first position and a second position. A pretensioner exerts a pretension force on the movable element urging it to the first position. A permanent magnet produces a magnetic field exerting a force on the movable element urging it to the second position. A coil produces, when energized in a first direction, a magnetic field exerting a force on the movable element urging it to the second position. The combined magnetic field of the magnet and the coil exerts a force on the movable element which is higher than the pretension force.

    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.

    摘要: A lithographic apparatus includes a mask or reticle masking device configured to block radiation. The masking device includes a reflective blade. The reflective blade may include a mirrored blade, which may be used in the scanning (Y) direction, and which moves across the beam of radiation in use. The reflective blade provides within an illumination system an effective slit for a mask or reticle within the lithographic apparatus.
