Abstract:
1. An apparatus for processing a substrate, comprising: a proximity head having a head surface, the proximity head having a plurality of regions for delivering fluid and a plurality of regions for removing fluid, wherein at least one of the plurality of regions for delivering fluid further comprises a plurality of conduits substantially aligned along a length of the proximity head for delivering fluid; a fluid input and a fluid output coupled to the proximity head, the fluid input configured to supply a fluid to the plurality of regions for delivering fluid and the fluid output configured to remove the fluid through the plurality of regions for removing fluid so as to define a segment of a fluid meniscus between the head surface of the proximity head and the top surface of the substrate; and a fluid flow control device for managing fluid flow through the fluid input, the fluid flow control device having a plurality of restrictors aligned along a length of the proximity head, with each restrictor being associated with one of said conduits for setting either an on flow, an off flow, or a partial flow through selected ones of the plurality of conduits for delivering fluid, so as to define a size of the meniscus along the length of the proximity head; wherein the proximity head is configured for placement over a top surface of the substrate, such that the head surface of the proximity head faces down over the top surface, and is spaced apart from the top surface.
