  • Patent number: 8234739
    Abstract: Scrubbing apparatus is configured by methods so that discs are quickly cleaned and conveyed by selecting a total number of spiral brush segments, rates of brush rotation, and a pitch length of a helical junction that receives discs for cleaning and transport. A time period for cleaning and transporting discs depends on the pitch length, rotational speed and configurations of the segments. An increase of the cleaning time period may result from use of an increased number of brush segments. A group of discs is cleaned by the same spiral brush, by one-by-one insertion of the discs into the junctions, and transporting the discs through the same segments.

  • Patent number: 7997289
    Abstract: Discs roll along an inclined track through a chamber to expose opposite disc sides for cleaning. Energized fluid directed against the opposite sides removes particles from the discs, the fluid and particles exiting the chamber. Stop pins control a time period for cleaning and transporting the discs by selectively blocking or releasing the discs. The discs are stopped at many sections of a transducer, the sections being tailored to provide various cleaning characteristics. Within the chamber, the chamber is configured to minimize particles that originate other than by being adhered to the disc at a time when the disc is introduced into the chamber. Internal chamber configuration also minimizes retention of particles so that particles removed from one disc do not linger in the chamber for possible transfer to a disc that is cleaned in the same chamber at a later time.

  • Publication number: 20110030733
    Abstract: In one embodiment, a method for cleaning a substrate in a cleaning module is disclosed. The method includes an operation that receives the substrate into a first level of the cleaning module. In another operation, the substrate is spun while contemporaneously applying a cleaning fluid to top and bottom surfaces of the substrate. In yet another operation, the substrate is spun at a second level of the cleaning module. The method also includes an operation to dry the substrate in an enclosed cavity at a third level of the cleaning module.
