Zusammenfassung:Disclosed is a method and apparatus for polishing a semiconductor wafer. This invention describes a novel in situ method for eliminating residual slurry and slurry abrasive particles on the wafer. A reactant is added to the slurry during the end of the Chemical Mechanical Polish (CMP) process to dissolve the slurry and etch the abrasive particles.
