    摘要： A polishing composition contains a deterioration inhibitor for inhibiting deterioration of polishing capability of the polishing composition, an abrasive, and water. The deterioration inhibitor is at least one selected from polysaccharide and polyvinyl alcohol. The polysaccharide is starch, amylopectin, glycogen, cellulose, pectin, hemicellulose, pullulan, or elsinan. Among them, pullulan is preferable. The abrasive is at least one selected from aluminum oxide and silicon dioxide, preferably at least one selected from fumed silica, fumed alumina, and colloidal silica. The polishing composition can be suitably used in polishing for forming wiring a semiconductor device.

    摘要： A method for polishing an object to form wiring for a semiconductor device includes: removing part of an outside portion of a conductor layer through chemical and mechanical polishing to expose an upper surface of a barrier layer; and removing a remaining part of the outside portion of the conductor layer and an outside portion of the barrier layer through chemical and mechanical polishing to expose an upper surface of an insulator layer. When removing part of the outside portion of the conductor layer, the upper surface of the object is chemically and mechanically polished using a first polishing composition containing a film forming agent. Subsequently, the upper surface of the object is washed to remove a protective film formed on an upper surface of the conductor layer by the film forming agent in the first polishing composition. Thereafter, the upper surface of the object is chemically and mechanically polished again using a second polishing composition containing the film forming agent. Thus, the wiring of the semiconductor device is reliably formed.

    摘要： A polishing composition contains a surface irregularity-inhibitor, silicon dioxide, an acid, an oxidant, and water. The surface irregularity-inhibitor is at least one selected from, for example, stored polysaccharides and extracellular polysaccharides. The silicon dioxide is, for example, colloidal silica, fumed silica, or precipitated silica. The acid is at least one selected from, for example, nitric acid, hydrochloric acid, sulfuric acid, lactic acid, acetic acid, oxalic acid, citric acid, malic acid, succinic acid, butyric acid, and malonic acid. The oxidant is, for example, hydrogen peroxide, persulfate, periodate, perchlorate, nitrate salt, or an oxidative metallic salt. The polishing composition can be suitably used in polishing for forming wiring in a semiconductor device.

    摘要： A first polishing composition is used in chemical mechanical polishing for removing one part of the portion of a conductive layer positioned outside a trench. A second polishing composition is used in chemical mechanical polishing for removing the remaining part of the portion of a conductive layer positioned outside the trench and the portion of a barrier layer positioned outside the trench. The first polishing composition contains a specific surfactant, a silicon oxide, a carboxylic acid, an anticorrosive, an oxidizing agent, and water. The second polishing composition contains colloidal silica, an acid, an anticorrosive, and a completely saponified polyvinyl alcohol.
