Abrasive composition |
abstract |
The present invention provides a polishing composition capable of polishing elemental silicon at a higher polishing rate. The polishing composition of the present invention is used for polishing an object to be polished comprising elemental silicon and a silicon-containing compound other than elemental silicon, the polishing composition comprising abrasive grains and a dispersion medium, and the abrasive grains have a unit surface area of The number of silanol groups exceeds 0 pieces/nm 2 and is 2.0 pieces/nm 2 or less. |
