WebSep 30, 2015 · Abstract: Tungsten CMP process involves an electrochemical alteration of metal surface and mechanical removal of the modified film. Electrochemical alteration means oxidation and corrosion of tungsten surface, so some extent of tungsten dishing and recess is very natural phenomena of tungsten CMP. Webinterconnect process. Slurry chemical corrosion was found to be enhanced when the slurry was diluted by deionized (DI) water during rinsing just after CMP. Since the corrosion inhibitor, benzotriazole (BTA), reduces the Cu removal rate, adding it to the rinse solution prevents chemical corrosion more effectively than adding it to the slurry.
