Compositions and methods for cmp of phase change alloys |
| abstract |
The present invention provides a chemical-mechanical polishing (CMP) composition suitable for polishing a substrate comprising a phase change alloy (PCA), such as a germanium-antimony-tellurium (GST) alloy. The composition comprises not more than 6% by weight of a particulate abrasive material in combination with an optional oxidizing agent, at least one chelating agent, and an aqueous carrier therefor. The chelating agent comprises a compound or combination of compounds capable of chelating a phase change alloy or component thereof (e.g., germanium, indium, antimony and/or tellurium species) that is present in the substrate, or chelating a substance that is formed from the PCA during polishing of the substrate with the CMP composition. A CMP method for polishing a phase change alloy-containing substrate utilizing the composition is also disclosed. |
