Lithographic apparatus, device manufacturing method, and device manufactured thereby

摘要

A lithographic projection apparatus comprising a first radiation system for providing a first projection beam of radiation; a second radiation system for providing a second projection beam of radiation; a support structure for supporting a first patterning structure and a second patterning structure, the first patterning structure serving to pattern the first projection beam according to a second pattern and the second patterning structure serving to pattern the second projection beam according to a second pattern; a substrate table for holding a substrate; a projection system for combining the first and second patterned beams and projecting the combined beam onto a target portion of the substrate.
