Patent ID: 7387689

Claim:
A method for processing substrate, comprising: applying a first fluid onto a surface of a substrate; applying a second fluid onto the surface of the substrate, the second fluid being applied in close proximity to the application of the first fluid, and the applying of the first fluid and second fluid being through a proximity head having a head surface that is placed in non-contact close proximity to the surface of the substrate; and removing the first fluid and the second fluid from the surface of the substrate, the removing being processed just as first fluid and the second fluid are applied to the surface of the substrate, the removing being through the proximity head when placed in the non-contact close proximity to the surface of the substrate; wherein the applying and the removing is directed by the proximity head defines a controlled meniscus that is maintained between the surface of the substrate and a surface of the proximity head, the surface of the proximity head being defined to include substantially flat surface regions and discrete holes for defining conduits for applying the first and second fluid and removing the first and second fluid, the discrete holes extending through the head surface of the proximity head.
