| description | An object of the present invention is to provide a polishing liquid for CMP with which polishing scratches can be reduced and a sufficiently high polishing rate can be obtained in a CMP step for an ILD film, aggregation of an abrasive grain is difficult to occur, and high flatness is obtained, and provide a polishing method using the same. The polishing liquid for CMP according to the present invention is a polishing liquid for CMP containing an abrasive grain, an additive, and water, wherein the abrasive grain comprises a cerium-based particle, and the additive comprises a 4-pyrone-based compound and at least one of a nonionic surfactant or a cationic surfactant: [wherein X11, X12, and X13 each independently represent a hydrogen atom or a monovalent substituent.] |
