Abstract:
1. An imaging apparatus comprising: a programmable patterning structure configured to pattern a beam of radiation, the programmable patterning structure including a plurality of separate patterning sub-elements, the sub-elements being configured to generate a patterned sub-beam; a combining structure configured to combine the plurality of patterned sub-beams into a single patterned image, the combining structure including at least one of a group consisting of a reflector and a beam splitter that receive the corresponding patterned sub-beam; and a projection system configured to project the patterned image onto a target portion of a substrate, wherein at least one of the patterned sub-beams is spatially modulated, and wherein the plurality of separate patterned sub-elements includes an array of individually controllable radiation modulating devices.
