Abstract:
A method for exposing a radiation-sensitive material of a microlithographic substrate to a selected radiation, comprising:directing the radiation along a reticle radiation path segment toward a reticle; passing the radiation from the reticle and to the microlithographic substrate along a substrate radiation path segment at the microlithographic substrate; moving the reticle along a reticle path generally normal to the reticle radiation path segment; and moving the microlithographic substrate relative to the radiation path along a substrate path, the substrate path having a first component generally parallel to the substrate radiation path segment, and the substrate path having a second component generally perpendicular to the substrate radiation path segment, wherein the microlithographic substrate moves generally parallel to and generally perpendicular to the substrate radiation path segment toward and away from the reticle while the reticle moves along the reticle path, and wherein the microlithographic substrate oscillates toward and away from the reticle along a first axis generally parallel to the substrate radiation path segment while the microlithographic substrate simultaneously moves along a second axis generally perpendicular to the substrate radiation path segment.
