Abstract:
A topography measurement system comprising a radiation source configured to generate a radiation beam, a spatially coded grating configured to pattern the radiation beam and thereby provide a spatially coded radiation beam, optics configured to form an image of the spatially coded grating at a target location on a substrate, detection optics configured to receive radiation re-fleeted from the target location of the substrate and form an image of the grating image at a second grating, and a detector configured to receive radiation transmitted through the second grating and produce an output signal.

Claim (Index 19):
A lithographic apparatus comprising:\n 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; a projection system configured to project the patterned radiation beam onto a target portion of the substrate; and a topography measurement system for measuring a topography of the substrate, the measurement system comprising:\n a spatially coded grating configured to pattern a second radiation beam; \n a second grating configured to receive the patterned second radiation beam reflected from a target location on the substrate; and \n a detector configured to receive the reflected patterned second radiation beam via the second grating and to supply an output signal representative of the reflected patterned second radiation beam received via the second grating.
