    摘要: Object: To provide a polishing composition which is capable of polishing a tantalum-containing compound at a high stock removal rate and whereby the copper surface after polishing is scarcely corroded, and to provide a polishing process where dishing can be minimized. Means to accomplish the object: A polishing composition comprising an abrasive, oxalic acid, an ethylenediamine derivative, a benzotriazole derivative and water and not containing an oxidizing agent, and a polishing composition comprising an abrasive, oxalic acid, an ethylenediamine derivative, a benzotriazole derivative, water and hydrogen peroxide. Further, a polishing process for forming a copper printed wiring, which is a polishing process for a semiconductor device and which comprises a first polishing step wherein polishing is completed immediately before reaching a barrier layer while a copper layer still slightly remains, and second and third polishing steps wherein the remaining copper layer and the barrier layer are polished, wherein in the second polishing step, a polishing composition containing hydrogen peroxide is used and all the copper layer to be removed, is removed by polishing, and then, in the third polishing step, a polishing composition not containing hydrogen peroxide is used and all the barrier layer to be removed, is removed by polishing.

    摘要: The method of polishing a copper layer of a substrate is capable of improving a stock removal rate, etc. The method comprises the steps of: supplying a substrate onto an polishing pad of an polishing plate with a copper layer facing the polishing pad; pressing the substrate onto the polishing pad, with a backing pad, by a press head; relatively rotating the press head with respect to the polishing plate, with supplying polishing slurry onto the polishing pad. The backing pad is made of a material whose Asker C hardness is 75-95 and whose compressibility is 10% or less. The polishing slurry includes a chelating agent for chelating copper, an etching agent for etching the surface of copper layer, an oxidizing agent for oxidizing the surface of copper layer, and water.
