Abstract:
1. An apparatus for patterning a workpiece arranged at an image plane and covered at least partly with a layer sensitive to electromagnetic radiation, comprising: a source emitting electromagnetic radiation onto an object plane, an SLM comprising a plurality of on-off object pixels, adapted to receiving and modulating said electromagnetic radiation at said object plane in accordance with a pattern and relaying said electromagnetic radiation toward said workpiece, a synchronizer to synchronize the motion of the workpiece relative to the pattern relayed from said SLM onto said workpiece, and an image-deflecting element arranged between said SLM and said workpiece adapted to deflect said relayed pattern description, wherein the modulation creates coherent sub-images on the workpiece and several sub-images are non-coherently superposed to create a final image.
