    摘要: The present invention provides a chemical-mechanical polishing (CMP) composition suitable for polishing a substrate comprising a phase change material (PCM), such as a germanium-antimony-tellurium (GST) alloy. The composition comprises a particulate abrasive material in combination with lysine, an optional oxidizing agent, and an aqueous carrier therefor. CMP methods for polishing a phase change material-containing substrate utilizing the composition are also disclosed.
