20110027994POLISHING SLURRY FOR CMP - A polishing liquid for CMP has a composition loaded with, for example, an inorganic salt, a protective film forming agent and a surfactant capable of imparting a dissolution accelerating activity to enlarge a difference between polishing speed under non-load and polishing speed under load. By virtue of this polishing liquid for CMP, there can be simultaneously accomplished a speed increase for increasing CMP productivity, and wiring planarization for miniaturization and multilayer formation of wiring.02-03-2011

20100301265POLISHING SLURRY AND METHOD OF POLISHING - A polishing slurry comprises a metal-oxidizing agent, a metal anticorrosive agent, an oxidized metal dissolving agent and water. The oxidized metal dissolving agent is at least one kind selected from the group consisting of an acid in which the negative value of the logarithm of the dissociation constant Ka (pKa) of a first dissociable acid group is 3.5 or more, an ammonium salt of the acid and an organic acid ester of the acid. The pH of the polishing slurry is within the range of 3 to 4. The concentration of the metal-oxidizing agent is within the range of 0.01 to 3 percent by weight. In the wiring-formation process of the semiconductor device, the conductor used for the barrier layer can be polished at a high polishing rate by using the polishing slurry having the low polishing particle concentration and the low metal anticorrosive agent concentration.12-02-2010
