| 摘要 |
A polishing composition is disclosed containing a nonionic active agent with a molecular weight of 1,000 or more and less than 100,000 and an HLB value of not less than 17, a basic compound, and water. The nonionic active agent is preferably an oxyalkylene homopolymer or a copolymer of different oxyalkylenes. The polishing composition may further contain at least one of silicon dioxide and a water-soluble polymer. The polishing composition is used, for example, in polishing the surface of semiconductor substrates such as silicon wafers. |
