Abstract:
A method and apparatus disclosed herein apply to processing a substrate, and more specifically to a method and apparatus for improving photolithography processes. The apparatus includes a chamber body, a substrate support disposed within the chamber body, and an electrode assembly. The substrate support has a top plate disposed above the substrate support, a bottom plate disposed below the substrate support, and a plurality of electrodes connecting the top plate to the bottom plate. A voltage is applied to the plurality of electrodes to generate an electric field. Methods for exposing a photoresist layer on a substrate to an electric field are also disclosed herein.
