    摘要: A method and associated composition for chemical mechanical planarization of a chalcogenide-containing substrate (e.g., germanium/antimony/tellurium (GST)-containing substrate) are described. The composition and method afford low defect levels as well as low dishing and local erosion levels on the chalcogenide-containing substrate during CMP processing.
