Abstract:
A scrubbing assembly for a wafer-cleaning device, having a base, comprising:a scrubber disposed on the base in a manner such that the scrubber moves between a first position and a second position, wherein the scrubber scrubs a wafer when the scrubber is located in the first position; a cup, for receiving DI water, disposed on the base and provided with a plurality of spraying holes, wherein the scrubber is located inside the cup and in contact with the DI water therein when the scrubber is located in the second position; and an oscillator disposed at the cup, wherein the oscillator vibrates the DI water when the scrubber is located inside the cup and in contact with the DI water; and a discharging device, electrically connected to the cup, for discharging the DI water in the cup after the scrubber scrubs a predetermined number of the wafer; a first water-supplying device electrically connected to the discharging device so that the first water-supplying device supplies the DI water after the discharging device discharges the DI water from the cup; and wherein the discharging device and the first water-supplying device cooperate to establish a level of DI water within the cup and the plurality of spraying holes are located above the water level so that the plurality of spraying holes may be used to clean the scrubber when the scrubber is inside the cup but spaced above the water level.
