  • Patent number: 9613833
    Abstract: Disclosed are pre-wetting apparatus designs and methods for cleaning solid contaminants from substrates prior to through resist deposition of metal. In some embodiments, a pre-wetting apparatus includes a process chamber having a substrate holder, and at least one nozzle located directly above the wafer substrate and configured to deliver pre-wetting liquid (e.g., degassed deionized water) onto the substrate at a grazing angle of between about 5 and 45 degrees. In some embodiments the nozzle is a fan nozzle configured to deliver the liquid to the center of the substrate, such that the liquid first impacts the substrate in the vicinity of the center and then flows over the center of the substrate. In some embodiments the substrate is rotated unidirectionally or bidirectionally during pre-wetting with multiple accelerations and decelerations, which facilitate removal of contaminants.
