| titleOfInvention |
Method of chemical mechanical polishing |
| abstract |
It is an object of the invention to provide an aqueous dispersion for CMP that produces no scratches on polishing surfaces and that polishes with an adequate rate, when used for polishing of copper and the like. The aqueous dispersion of the invention contains water and polymer particles composed of a polymer with a specific functional group, and it may also contain a complexing agent, a compound that forms a passivation film on polishing surfaces and/or an oxidizing agent. The specific functional group is a functional group that can react with the metals of polishing surfaces or that can form a cation, and it is preferably selected from among amino, pyridyl and acrylamide groups. The polymer can be obtained using a initiator and/or monomer possessing the specific functional group. The polymer may also have a crosslinked structure. |
