Abstract
This invention relates to an improved micro lithographic writer that sweeps a modulated pattern across the surface of a workpiece. The SLM disclosed works in a diffractive mode with a continuous or quasi-continuous radiation source. It uses a long and narrow SLM and takes advantage of diffractive effects along the narrow axis of the SLM to improve writing characteristics along that axis.
