Abstract
Generally, examples described herein relate to systems and methods for processing a substrate, and more particularly, for removing an edge bead or other source of contamination from an edge of a substrate. An example is a processing system including a chamber, a substrate handler within the chamber, and a radiation generator within the chamber. The substrate handler is configured to secure a substrate. The substrate handler is operable to position an edge surface of the substrate such that radiation propagating from the radiation generator is directed to the edge surface of the substrate, and operable to position a periphery region of a deposit surface of the substrate that is perpendicular to and along the edge surface such that radiation propagating from the radiation generator is directed to the periphery region.
