Abstract
A lithographic apparatus includes a first diffraction grating configured to create a first plurality of spatially coherent radiation beams and a second diffraction grating configured to receive at least a portion of the first plurality of spatially coherent radiation beams and to create, based on the first plurality of spatially coherent radiation beams, a second plurality of spatially coherent radiation beams. The apparatus also includes a beam combiner adapted to redirect and combine at least a portion of the second plurality of spatially coherent radiation beams onto a surface of a substrate to form an interference pattern.
