Abstract:
1. A substrate preparation system, comprising: a head having a head surface, the head surface configured to be proximate to a surface of the substrate when in operation; a first conduit for delivering a first fluid to the surface of the substrate through the head; a second conduit for delivering a second fluid to the surface of the substrate through the head, the second fluid being different than the first fluid; and a plurality of third conduits being defined in the head so as to at least partially surround the first conduit and the plurality of third conduits being configured for removing each of the first fluid and the second fluid from the surface of the substrate; wherein the head surface has flat surface regions, and the head surface is defined so that the first conduit, the second conduit, and the plurality of third conduits are defined by discrete holes that reside at the head surface and extend through the flat surface regions of the head surface.
