Abstract: A polishing slurry including Al-doped silica and water for low dielectric material is disclosed, it is characterized in that, it further contains active micro-molecule materials which are ammonium-ion or quaternary ammonium ion containing compound. The present polishing slurry has promotion on polishing low dielectric material such as CDO and TEOS or SION etc., while it has little effect on polishing speed for Ta and Cu. Thus it can greatly improve the polishing selectivity for substrates. Moreover, the present polishing slurry can greatly decrease the surface defects such as scratch, corrosion, pitting erosion and the like.

Abstract: A polishing slurry containing blended abrasives for low dielectric material is disclosed, which includes two or more kinds of polishing abrasives, wherein, one of the abrasives is Al-doped silica, and the second abrasive is the one selected from silica, alumina, alumina -coated silica or zirconia-coated silica or their combinations. The present polishing slurry not only can effectively adjust the polishing speed of low dielectric carbon-doped silica (CDO) and silica, but also can prevent local and throughout corrosion during metal polishing, thus can improve the acceptability. Moreover, it is useful in integrate circuit which contains metal,metal barrier, carbon-doped silica and silica simultaneously.
