Paper Abstract

A Microstepper exposure tool for high-resolution imaging applications incorporating the F2 157nm laser is described. Details are presented of the optical architecture including beams shaping, homogenization and imaging objectives. Results from the high-resolution metrology, workpiece positioning and gas purging subsystems used in the tool are discussed. Use of the Microstepper for 70nm-node deep-iv lithography and submicron micromachining applications is presented.
