Abstract
Methods for processing substrate through a head that is configured to be placed in close non-contact proximity to a surface of a substrate are provided. One method includes applying a first fluid onto the surface of the substrate from conduits in the head when the head is in close proximity to the surface of the substrate and removing the first fluid from the surface of the substrate. The removing is processed just as first fluid is applied to the surface of the substrate, and the removing ensures that the applied first fluid is contained between a surface of the head and the surface of the substrate and the first fluid being applied and removed defines a controlled meniscus. The method further includes moving the controlled meniscus over different regions of the surface of the substrate when movement of the head or the substrate is dictated. The moving of the controlled meniscus enables processing of part or all of the surface of the substrate using the first fluid.
