Abrasive and slurry |
| abstract |
An object of the present invention is to provide an abrasive capable of polishing a surface to be polished such as a SiO 2 insulating film at high speed without scratching. A polishing agent comprising a slurry in which cerium oxide particles are dispersed in a medium, the cerium oxide particles comprising cerium oxide particles having a crystal grain boundary composed of two or more crystallites, and having a crystal grain boundary. The cerium oxide particles are an abrasive that is 5 to 100% by volume of the total cerium oxide particles contained in the slurry. [Selection figure] None |
