    Abstract: A lithographic apparatus includes a stage to hold an object, the stage being moveable relative to a reference structure in a motion range; a magnet structure to provide a spatially varying magnetic field in at least a part of the motion range, the magnet structure being moveable relative to the reference structure and the stage; a first position measurement system to provide a first measurement signal corresponding to a position of the stage and/or the object in a measurement direction relative to the reference structure; a second position measurement system to provide a second measurement signal corresponding to a position of the stage relative to the magnet structure; and a data processor to correct the first measurement signal with a value dependent on the second measurement signal to provide a corrected first measurement signal representative of the position of the stage and/or the object relative to the reference structure in the measurement direction.

    Abstract: A lithographic apparatus includes an illumination system configured to condition a radiation beam, a support constructed to support a patterning device, the patterning device being capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam, a substrate table constructed to hold a substrate, and a projection system configured to project the patterned radiation beam onto a target portion of the substrate. The projection system is mounted on a reference structure of the lithographic apparatus by a mount of the lithographic apparatus. The mount includes a first piezoelectric element to exert a force on the projection system, a second piezoelectric element to measure the force, and an interconnection member interposed between the first and second piezoelectric elements, the interconnection member comprising a cut.

    Abstract: A lithographic projection apparatus includes a first object table configured and arranged to hold a patterning structure capable of patterning a projection beam of radiation according to a desired pattern and a second object table configured and arranged to hold a substrate. A positioning structure is configured and arranged to generate a force so as to move one of the object tables with respect to a projection system during an imaging operation. Processing circuitry is configured and arranged to read from a data storage device a compensation force value that corresponds to a value of a signal representing a position of said object table and to generate a force adjustment signal based on the compensation force value. The positioning structure is further configured and arranged to generate the force according to the force adjustment signal.
