Abstract:
1. An apparatus for processing a substrate, comprising: a top and bottom proximity head defined in a non-contact orientation from the substrate, each proximity head defined to generate a fluid meniscus to process a substrate surface, the proximity head having a head surface that includes a plurality of discrete conduits for delivering and removing fluid to define the fluid meniscus that is contained between the head surface and the substrate surface; a chamber configured to house and surround the top and bottom proximity heads, wherein the top proximity head faces the fluid meniscus down on top of the substrate and the bottom proximity head faces the fluid meniscus up toward the substrate; and an environment generator coupled to the chamber, the environment generator is defined to produce an environmental control gas that is communication with the chamber through a conduit, such that the chamber maintains the environmental control gas to define a humidity level in and around the proximity head that is housed by the chamber.
