titleOfInvention |
Composition for chemical mechanical polishing and chemical mechanical polishing method |
abstract |
The present invention provides a chemical mechanical polishing composition and a chemical mechanical polishing method, which can polish a semiconductor substrate containing tungsten, cobalt and other conductive metals at high speed and flatly, and can reduce surface defects after polishing. The chemical mechanical polishing composition of the present invention contains: (A) silica particles containing a functional group represented by the following general formula (1); and (B) selected from carboxylic acids containing unsaturated bonds and their salts At least one of the groups. -COO - M + ・・・・・(1) (M + represents a monovalent cation.) |
