Abstract:
1. A substrate preparation system, the system comprising: a brush coupled to a shaft, the shaft arranged to move between a second height (H a front head defined to be positioned in close proximity to a front surface of the substrate, the front head having a plurality of conduits for delivering and removing a fluid so as to define a fluid meniscus between the front head and a front surface of the substrate; and a back head defined to be positioned in close proximity to the back surface of the substrate, the back head being positioned substantially opposite to the front head, and the back head having a plurality of conduits for delivering and removing a fluid so as to define a fluid meniscus between the back head and the back surface of the substrate, wherein the front head and the back head are coupled to arms that orient the front head and the back head in a path that is horizontal and substantially parallel to the substrate and the arms orient the front head and the back head in a vertical direction to enable defining the front head and the back head in close proximity to the front surface of the substrate and the back surface of the substrate, respectively, wherein the first height of shaft that couples to the brush is spaced apart from the path of the back head.
