Patent abstract
This invention provides a polishing medium for CMP, comprising an oxidizing agent, a metal-oxide-dissolving agent, a protective-film-forming agent, a water-soluble polymer, and water, and a polishing method making use of this polishing medium. Also, it is preferable that the water-soluble polymer has a weight-average molecular weight of 500 or more and the polishing medium has a coefficient of kinetic friction of 0.25 or more, a Ubbelode's viscosity of from 0.95 mPa·s (0.95 cP) to 1.5 mPa·s (1.5 cP) and a point-of-inflection pressure of 5 kPa (50 gf/cm2).
