Abstract:
1. A microlithographic system that exposes a radiation sensitive layer over a workpiece, the system including: an SLM, at least 1000 micro mirrors on a long axis and from 2 to 20 micro mirrors on a narrow axis, operating in diffraction mode to modulate and relay radiation; an illuminator that illuminates the SLM with locally coherent and continuous or quasi-continuous radiation; relay optics that project the radiation from the SLM micro mirrors onto an image plane with distinct mapping from the micro mirrors that uses local coherence to produce additive and subtractive coherent intensity effects and to sharpen edge definition on the image plane; and sweep mechanics that sweep the projected radiation across the image plane as the SLM modulates the projected radiation.
