    • PURPOSE: To obtain an aqueous dispersion for chemical machine polishing useful for polishing copper, having a high polishing rate, capable of decreasing an erosion rate in overpolishing. CONSTITUTION: This aqueous dispersion for a chemical machine polishing comprises a heterocycle-containing compound, a surfactant and an oxidizing agent and has the mass ratio of the heterocycle-containing compound to the surfactant of 1:10-1:0.03. The aqueous dispersion further can contain a abrasive grain. Quinaldic acid, benzotriazole, etc., preferably as the heterocycle-containing compound. A sulfonate such as potassium dodecylbenzenesulfonate, ammonium dodecylbenzenesulfonate, etc., are preferably as the surfactant and ammonium persulfate, hydrogen peroxide, etc., are preferable as the oxidizing agent. An inorganic particle such as colloidal silica, etc., an organic particle such as a polymer particle, etc., or an organic inorganic composite particle obtained by combining both the particles is used as the abrasive grain.
    • 目的:获得能够降低抛光速度的抛光速度高的用于抛光铜的化学机械抛光用水性分散体。 构成:用于化学机械抛光的水性分散体包含含杂环化合物,表面活性剂和氧化剂,并且含杂环化合物与表面活性剂的质量比为1:10-1:0.03。 水性分散体还可以含有磨粒。 季戊酸,苯并三唑等,优选作为含杂环化合物。 优选十二烷基苯磺酸钾,十二烷基苯磺酸铵等磺酸盐作为表面活性剂,优选过硫酸铵,过氧化氢等作为氧化剂。 作为磨粒,使用胶体二氧化硅等无机粒子,聚合物粒子等有机粒子或将这两种粒子组合而成的有机无机复合粒子。
