    Abstract: A lithography apparatus and device manufacturing methods are disclosed. A lithography apparatus includes a support stage, and a measurement system including a sensor part and a reference part, the measurement system being configured to determine the position and/or orientation of the support stage, or of a component mounted on the support stage, relative to a reference frame by using the sensor part to interact with the reference part, wherein: the reference frame comprises N sub-frames coupled together so as to behave predominantly as a single rigid body with respect to vibrations below a first reference frequency and predominantly as an N-body system with respect to vibrations above a second reference frequency, where N is an integer greater than 1.

    Abstract: Disclosed is a system configured to project a beam of radiation onto a target portion of a substrate within a lithographic apparatus. The system includes a radiation source. The radiation source includes a grating structure operable to suppress the zeroth order of reflected radiation for at least a first component wavelength. The grating structure has a periodic profile including regularly spaced structures providing three surface levels, such that radiation diffracted by the grating structure includes radiation of three phases which destructively interfere for at least the zeroth order of the reflected radiation for the first component wavelength. The grating structure is on a radiation collector within the source.

    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.
