发明名称 Method and apparatus for conditioning a polishing pad with sonic energy
摘要 A method and apparatus for conditioning a polishing pad is described, wherein the polishing pad has a polishing surface for polishing the semiconductor wafer. The method includes positioning a sonic energy generator above the polishing surface of the polishing pad, and applying sonic energy to the polishing surface of the polishing pad. The apparatus a sonic energy generator adapted to be positioned above the polishing surface, the sonic energy generator including a transducer, and a liquid carrier in flow communication with the transducer, wherein the transducer transmits sonic energy into the liquid carrier and the liquid carrier is applied to the polishing surface of the polishing belt.
