发明名称 Methods and compositions for chemical mechanical polishing substrates
摘要 Methods and compositions are provided for planarizing a substrate surface with reduced or minimal defects in surface topography. In one aspect, a method is provided for processing a substrate comprising a dielectric material and polysilicon material disposed thereon, polishing the polysilicon material with a high topography selective polishing composition, and polishing the polysilicon material with a material selective composition.
