A method of polishing an object having a conductor layer made of copper or a copper alloy
A polishing composition contains a polishing accelerator, a water-soluble polymer including a constitutional unit originating from a polymerizable compound having a guanidine structure such as dicyandiamide, and an oxidant. The water-soluble polymer may be a water-soluble polymer including a constit...

Zusammenfassung: | A polishing composition contains a polishing accelerator, a water-soluble polymer including a constitutional unit originating from a polymerizable compound having a guanidine structure such as dicyandiamide, and an oxidant. The water-soluble polymer may be a water-soluble polymer including a constitutional unit originating from dicyandiamide and a constitutional unit originating from formaldehyde, a diamine or a polyamine. |
