1. A system for processing a substrate, the system comprising:

  • a first proximity head having a plurality of dispensing nozzles and a plurality of suction ports substantially surrounded by the plurality of dispensing nozzles, the first proximity head capable of defining a first meniscus over a surface of the substrate when present, and wherein the first proximity head does not include surrounding gas inputs, separate from the dispensing nozzles, disposed beside of the plurality of dispensing nozzles; and

    a second proximity head for generating a second meniscus over the surface of the substrate when present, the second proximity being positioned adjacent to the first proximity head, the second proximity head includes a plurality of dispensing nozzles that are substantially surrounded by a plurality of suction ports, and further including a plurality of gas nozzles substantially surrounding the suction ports, wherein the plurality of dispensing nozzles and plurality of suction ports are formed in a respective face of the first and second proximity heads, the respective faces having a substantially flat surface, and the first and second proximity heads having a length that is greater than a width, and the length extends at least a diameter of the substrate;

    wherein the positioning of the first and second proximity heads adjacent to each other orients the length of the first and second proximity heads parallel to each other;

    wherein the first and second proximity heads direct the respective faces in a same direction toward and proximate to the substrate when present;

    a mechanism to hold the first and second proximity heads adjacent and parallel to each other.
