Claim:
1. A method for processing a semiconductor wafer, comprising: providing the semiconductor wafer into a Chemical Mechanical Polishing (CMP) module; polishing the semiconductor wafer; removing the semiconductor wafer from the CMP module; cleaning the semiconductor wafer by a brush member surrounding a rotation shaft; supplying a cleaning liquid to an agitation transducer and agitating the cleaning liquid to an agitated cleaning liquid by the agitation transducer, wherein the agitation transducer circumferentially surrounds a segment of the rotation shaft which is not covered by the brush member; supplying the agitated cleaning liquid along a predetermined path, wherein at least a section of the predetermined path is parallel to a rotation axis about which the rotation shaft rotates; and cleaning the brush member by using the agitated cleaning liquid.
