    摘要: The present invention provides chemical-mechanical polishing (CMP) compositions suitable for polishing a substrate comprising a germanium-antimony-tellurium (GST) alloy. The CMP compositions of the present invention are aqueous slurries comprising a particulate abrasive, a water-soluble surface active agent, a complexing agent, and a corrosion inhibitor. The ionic character of the surface active material (e.g., cationic, anionic, or nonionic) is selected based on the zeta potential of the particulate abrasive. A CMP method for polishing a GST alloy-containing substrate utilizing the composition is also disclosed.

    摘要: The invention provides chemical-mechanical polishing (CMP) compositions and methods for polishing a silicon-containing substrate. A method of the invention comprises the steps of contacting a silicon-containing substrate with a polishing pad and an aqueous CMP composition, and causing relative motion between the polishing pad and the substrate while maintaining a portion of the CMP composition in contact with the surface of the substrate to abrade at least a portion of the substrate. The CMP composition comprises a ceria abrasive, a polishing additive bearing a functional group with a pKa of about 4 to about 9, a nonionic surfactant with an hydrophilic portion and a lipophilic portion wherein the hydrophilic portion has a number average molecular weight of about 500 g/mol or higher, and an aqueous carrier, wherein the pH of the composition is 7 or less. The method reduces defects on the wafers, particularly local areas of high removal. The method is also useful for polishing dielectric silicon-containing substrates at a high rate relative to semiconductor silicon-containing substrates.
