    • A cleaning agent for substrates and a cleaning method are disclosed which enable to effectively remove fine particles and impurities (metal impurities) derived from various metals on a substrate surface without roughening the substrate surface, especially the surface of a semiconductor substrate or causing corrosion or oxidation of metal wiring, especially of copper wiring formed on the substrate surface. The cleaning agent and cleaning method further enable to remove carbon defects on the substrate surface at the same time without removing a metal corrosion inhibitor-Cu coating film, especially a Cu-BTA coating film. The cleaning agent for substrates contains [I] an organic acid having at least one carboxyl group and/or [II] a complexing agent and [III] an organic solvent selected from the group consisting of (1) monovalent alcohols, (2) alkoxy alcohols, (3) glycols, (4) glycol ethers, (5) ketones and (6) nitriles. The method for cleaning a substrate surface is characterized by processing the substrate surface with such a cleaning agent.
    • 公开了一种用于基板的清洁剂和清洁方法,其能够有效地去除在基材表面上衍生自各种金属的细小颗粒和杂质(金属杂质),而不会使基板表面,特别是半导体基板的表面或者导致腐蚀或氧化 的金属布线,特别是形成在基板表面上的铜布线。 清洗剂和清洗方法能够同时去除基板表面上的碳缺陷,而不需要除去金属腐蚀抑制剂Cu涂膜,特别是Cu-BTA涂膜。 用于底物的清洁剂含有[I]具有至少一个羧基的有机酸和/或[II]络合剂,[III]选自(1)一价醇,(2)烷氧基 醇,(3)二醇,(4)二醇醚,(5)酮和(6)腈。 用于清洁衬底表面的方法的特征在于用这种清洁剂处理衬底表面。
