发明名称 Use of corrosion inhibiting compounds to inhibit corrosion of metal plugs in chemical-mechanical polishing
摘要 A process of inhibiting a corrosion of metal plugs formed in integrated circuits is described. The corrosion inhibiting process includes providing a partially fabricated integrated circuit surface including the metal plugs on a polishing pad to carry out chemical-mechanical polishing, introducing slurry including a corrosion inhibiting compound on the polishing pad in sufficient concentration to inhibit corrosion of the metal plugs of the partially fabricated integrated circuit surface, and polishing the partially fabricated integrated circuit surface.
