Beschreibung
Zusammenfassung:	Provided herein are compositions and methods for polishing surfaces comprising cobalt and optionally a low-K material, e.g., in semiconductor device fabrication. Embodiments include a slurry for chemical mechanical polishing a surface comprising cobalt and low-K materials, such as Black Diamond (BD) or SiN, comprising a complexor, an oxidizer, an abrasive, a Co corrosion inhibitor and an ILD suppressor.
