    Abstract: An immersion lithographic apparatus includes a projection system, a first table with a first planar surface and a second table with a second planar surface, the first and second planar surfaces being substantially coplanar, a liquid confinement system configured to spatially confine an immersion liquid to a volume with a first surface area that is coplanar with the first and second planar surfaces, and is substantially smaller than a second surface area of the top surface of the substrate, and a swap bridge member attached to the first table, the swap bridge member having an upper surface that is substantially coplanar with the first and second planar surfaces, wherein the upper surface of the swap bridge member is configured to serve as part of the liquid confinement system and to deform when the swap bridge member collides with the second table and to remain attached to the first table

    Abstract: A method is provided for determining surface parameters of a patterning device, comprising the steps of: positioning the patterning device with respect to a path of an exposure radiation beam using a first measurement system, providing the patterning device at a first focal plane of a chromatic lens arranged in a second measurement system, illuminating a part of a surface of the patterning device with radiation through the chromatic lens, wherein the radiation comprises a plurality of wavelengths, determining a position of the illuminated part of the patterning device in a first and second direction, collecting at least a portion of radiation reflected by the patterning device through the chromatic lens, measuring an intensity of the collected portion of radiation as a function of wavelength, to obtain spectral information of the illuminated area, and determining the surface parameters of the patterning device at the determined position from the spectral information.
