摘要: Disc shaped cleaning/polishing pads are disclosed for use on a cleaning/polishing apparatus wherein the surface of the cleaning/polishing pad comprises resilient members arranged in patterns which will facilitate the movement of fluids (deoinized water, chemical slurry, etc.) from the center region of the pad to the periphery of the pad. Arrangement of the resilient members on the pads may be spiral, swirl, concentric or any other suitable pattern which will direct fluids to the periphery of the pad upon rotation of the pad.

摘要: A brush conditioner for a semiconductor wafer cleaning tool including a pair if opposed, rotating flexible brushes. The conditioner is a wing-like structure having a leading edge and a trailing edge. The leading edge is forced against the rotating brushes flexing them to assist in removal of foreign material. The trailing edge tapers to a point and provides stability to the wing.
