发明名称 Polishing apparatus with slurry screening
摘要 A polishing apparatus and a polishing method can effectively prevent large diameter particles from being fed with slurry to an object to be polished. A large-diameter particle screener blocks or disperses large diameter particles from entering the slurry. Then, slurry free from large diameter particles is taken up from a slurry container by an intake pipe and fed to the object to be polished.
