Slurry for chemical mechanical polishing of cobalt-containing substrates |
abstract |
Methods and compositions for chemical mechanical polishing (CMP) cobalt-containing substrates are provided herein. The methods and compositions of this application involve the use of a complexing agent, an oxidizing agent, an abrasive, and a cobalt corrosion inhibitor comprising an amino acid having at least two acidic moieties. The method and composition of the present application can be used to achieve a high cobalt removal rate during the CMP process while effectively inhibiting corrosion. |
