ABSTRACT:
A lithography system comprises an illumination system that supplies radiation and a projection system comprising an optical system and a patterning device located at a pupil plane. The patterning device patterns the radiation and the optical system projects the patterned radiation onto a target portion of a substrate. In one example, an additional patterning device is located at an object plane of the lithography system and patterns the radiation before the patterning device at the pupil plane.
