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 20):
A topography measurement method comprising measuring a topography of a substrate, the measuring comprising:\n using a spatially coded grating configured to pattern a radiation beam; and thereby provide a spatially coded radiation beam; using a second grating; receiving via the second grating the patterned radiation beam reflected from a target location of the substrate; and supplying an output signal representative of the reflected patterned radiation beam received via the second grating.
