Apparatus for Contained Chemical Surface Treatment

摘要

Apparatuses for preparing a surface of a substrate using a proximity head includes a carrier to hold and move the substrate along an axis and a proximity head having a head surface with a plurality of outlet ports defined thereon. The proximity head is defined to be positioned proximate and over the carrier and the surface of the substrate. A length of the head surface of the proximity head is defined to be greater than a diameter of the substrate and at least partially overlapping over the carrier when the substrate is present. The proximity head includes a first set of outlet ports in a first region defining a first applicator that is configured to apply a non-Newtonian fluid between a surface of the carrier and the head surface of the proximity head. A second set of outlet ports in a second region of the proximity head defines a second applicator that is configured to apply a first chemistry to the surface of the substrate when present. The second region is adjacent to the first region. A third set of outlet ports in a third region of the proximity head defines a third applicator that is configured to apply the non-Newtonian fluid between the head surface of the proximity head and the surface of the substrate when present. The third region is defined adjacent to the second region. A fourth set of outlet ports is defined in the second region of the proximity head to substantially remove the first chemistry from the surface of the substrate when present.
