ABSTRACT:
A lithographic illumination apparatus and method includes receiving a plurality of source radiation beams from a plurality of corresponding radiation sources, deflecting the plurality of source radiation beams along a common beam path, thereby generating a projection beam of radiation, imparting the projection beam of radiation with a cross-section pattern, and projecting the patterned projection beam of radiation onto a target portion of a substrate.
