发明名称 Post-polish cleaning of oxidized substrates by reverse colloidation
摘要 A method for cleaning the surface of an oxidized semiconductor wafer subjected to a planarization polishing process is described. The planarization process employes a slurry which contains abrasive particles suspended in a liquid solution. The invented cleaning method removes remnant particles electrochemically by placing the polished wafers in a PH-controlled bath.
