Abstract
Some implementations described herein provide an exposure tool and associated methods of operation in which a scanner control system generates a scanner route for an exposure recipe such that the distance traveled by a substrate stage of the exposure tool along the scanner route is reduced and/or optimized for non-exposure fields on a semiconductor substrate. In this way, the scanner control system increases the productivity of the exposure tool, reduces processing times of the exposure tool, and increases yield in a semiconductor fabrication facility in which the exposure tool is included.
