Composition for chemical mechanical polishing and method for polishing |
| abstract |
Provided are a composition for chemical mechanical polishing and a method for polishing allowing a tungsten film- or silicon nitride film-containing semiconductor substrate to be polished at a high speed, while also enabling a reduction in the occurrence of a surface defect in the polished face after polishing. A composition for chemical mechanical polishing according to the present invention comprises (A) abrasive grains containing titanium nitride and (B) a liquid medium, wherein the absolute value of the zeta-potential of said (A) component in the composition for chemical mechanical polishing is 8 mV or higher. |
