    摘要: A method for cleaning and drying a front and a back surface of a substrate is provided. The method includes brush scrubbing the back surface of the substrate using a brush scrubbing fluid chemistry. The method further includes applying a front meniscus onto the front surface of the substrate upon completing the brush scrubbing of the back surface. The front meniscus includes a front cleaning chemistry that is chemically compatible with the brush scrubbing fluid chemistry.

    摘要: A method for using a monitor substrate to determine effectiveness of a cleaning operation is provided. The method includes selecting a substrate from a lot of substrates and inspecting a surface of the substrate to determine a roughness profile of the substrate. The monitor substrate is then processed through a cleaning operation, and the monitor substrate is patterned with die regions throughout. Each of the die regions has a plurality of areas defining distinct roughness simulations. The method the proceeds to inspecting the monitor substrate at one die region and at one of the plurality of areas in the one die region that most closely resembles the roughness profile of the substrate. The inspecting of the monitor substrate is configured to yield data regarding cleaning performance of the cleaning operation.

    摘要: A wheel for a conveyor system for transporting semiconductor wafers includes a first section for supporting a semiconductor wafer at a first level and a second section for supporting the wafer at a second level, with the first level being higher than the second level. In one embodiment, each of the first and second sections is semicircular. The first level may be substantially the same as a level at which the wafer is subjected to a wafer cleaning operation, and the distance the second level is below the first level may be in a range from about one sixteenth of an inch to about three sixteenths of an inch. A conveyor system for transporting wafers and a method for transferring wafers from a conveyor system to a wafer processing station also are described.

    摘要: A method and apparatus for processing wafer edges is disclosed. Pressure applied to the wafer at one end of A brush/pad assembly is greater than at the opposite end of the brush/pad assembly. The increased pressure causes wafer rotation to slow or to reverse direction as compared to less pressure applied by the brush/pad assembly. In one embodiment slowed rotation causes a difference in tangential velocity between the roller(s) and the wafer edge/bevel that causes pads in the roller(s) to process the edge/bevel of the wafer. In another embodiment, the opposite direction of rotation causes the wafer to rotate counter to rollers otherwise causing the wafer to rotate. Cleaning surfaces in the rollers clean the edges of the wafer whether rotation is slowed or reversed.
