    摘要: A polishing slurry for metal comprises an oxidizer, a metal oxide dissolving agent, a metal inhibitor, and water, wherein the metal inhibitor is at least one of a compound having an amino-triazole skeleton and a compound having an imidazole skeleton. The use of the polishing slurry for metal makes it possible to raise the polishing speed sufficiently while keeping the etching speed low, restrain the generation of corrosion of the surface of a metal and dishing, and form a metal-film-buried pattern having a high reliability in the process of formation of wiring of semiconductor devices.

    摘要: 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.

    摘要: A CMP slurry is mixed with an oxidant in polishing and contains a copper rust inhibitor, a water-soluble polymer, a pH controller capable of forming a complex with copper, and water, and is substantially free from abrasive. The CMP slurry effectively reduces dishing in chemical polishing of copper and forms reliable wiring. Preferably, the contents of the rust inhibitor, the water-soluble polymer, and the oxidant are 0.1 to 5 wt %, 0.05 to 5 wt %, and 0.01 to 5M relative to 1 liter of the CMP slurry, respectively, and the amount of the pH controller is a necessary amount for adjusting pH of the CMP slurry to 1.5 to 2.5.
