    摘要： It is an object of the present invention to provide an aqueous dispersion and CMP slurry that can achieve polishing at an adequate rate without producing scratches in the polishing surfaces of wafer working films, and a polishing process for wafer surfaces and a process for manufacture of a semiconductor device using them. A CMP slurry and the like of the present invention contains polymer particles with a crosslinked structure and a mean particle size of 0.13-0.8 &mgr;m. The CMP slurry may contain no surfactant, and may contain the surfactant of not greater than 0.15 wt %. A CMP slurry and the like of another present invention contains polymer particles and inorganic particles of silica, aluminum and the like. A mean particle size of the polymer particles may be not greater than a mean particle size of the inorganic particles. And the mean particle size of the inorganic coagulated particles may be 0.1-1.0 &mgr;m, and may be smaller than the mean particle size of the polymer particles. The CMP slurry is used as a polishing agent and a working film of a silicon oxide film, an aluminum film, a tungsten film or a copper film formed on a wafer is polished. And a semiconductor device is manufactured by using the CMP slurry.

    摘要： The object of the present invention is to provide an aqueous dispersion that can give the required properties for a wide range of uses including electronic materials, magnetic materials, optical materials and polishing materials, and to provide an aqueous dispersion for chemical mechanical polishing (CMP slurry) that gives an adequate polishing rate without creating scratches in polishing surfaces. Another object of the present invention is, to provide a method for manufacture of semiconductor devices using a CMP slurry that can control progressive erosion due to scratches and the like during polishing and that can achieve efficient flattening of working films, and to provide a method for formation of embedded wiring. The aqueous dispersion or CMP slurry of the present invention contains polymer particles made of thermoplastic resins or the like, and inorganic particles made of alumina, silica or the like, wherein the zeta potentials of the polymer particles and inorganic particles are of opposite signs, and they are bonded by electrostatic force to form aggregates as composite particles. The aggregates are subjected to ultrasonic wave irradiation or shear stress with a homogenizer to give more uniformly dispersed composite particles.
