Abstract:
Embodiments described herein relate to methods and apparatus for performing immersion field guided post exposure bake processes. Embodiments of apparatus described herein include a chamber body defining a processing volume. A pedestal may be disposed within the processing volume and a first electrode may be coupled to the pedestal. A moveable stem may extend through the chamber body opposite the pedestal and a second electrode may be coupled to the moveable stem. In certain embodiments, a fluid containment ring may be coupled to the pedestal and a dielectric containment ring may be coupled to the second electrode.
