Polishing composition |
| abstract |
An object of the present invention is to provide a new polishing composition that contributes to improving the quality of a device. There is provided a polishing composition containing: an abrasive grain having an organic acid immobilized on a surface thereof; a first water-soluble polymer having a sulfonic acid group or a group having a salt thereof, or a carboxyl group or a group having a salt thereof; a second water-soluble polymer different from the first water-soluble polymer; a nonionic surfactant; and an aqueous carrier, wherein the polishing composition is used for polishing an object to be polished. |
