Abstract
A substrate cleaning device includes a double-sided scrubber that directs a liquid to a substrate as it moves back-and-forth between a pair of rotating brushes. The device may also include a first set of nozzles and a second set of nozzles. The first set of nozzles may be configured to spray a first liquid at an interface between the substrate and rotating brushes and the second set of nozzles may be configured to spray a second liquid at the interface as the substrate moves back-and-forth between the pair of rotating brushes.
