Abstract:
To provide a polishing composition capable of realizing a polished surface having smoothness and few defects. A polishing composition contains a water-soluble polymer satisfying the following two conditions (A) and (B): Condition (A): in a first standard solution which contains silica having an average primary particle size of 35 nm, the water-soluble polymer, ammonia, and water and in which the concentration of the silica is 0.48% by mass, the concentration of the water-soluble polymer is 0.0125% by mass, and the pH is 10.0, the adsorption ratio which is a ratio of the amount of the water-soluble polymer adsorbed to the silica to the total amount of the water-soluble polymer contained in the first standard solution is 10% or more; and Condition (B): in a second standard solution which contains silica having an average primary particle size of 35 nm, the water-soluble polymer, ammonia, and water and in which the concentration of the silica is 0.48% by mass, the concentration of the water-soluble polymer is 0.0125% by mass, and the pH is 10.4, the adsorption ratio which is a ratio of the amount of the water-soluble polymer adsorbed to the silica to the total amount of the water-soluble polymer contained in the second standard solution is 65% or less.

Claim (Index 5):
A method for polishing a silicon substrate comprising:\n polishing a silicon substrate using the polishing composition according to  claim 1 .
