An object of the present invention is to provide a metal polishing composition which can polish a metal such as Cu and Ta at a high speed, has a higher efficiency of washing for a hydrophobic low dielectric constant film, and is excellent stability without precipitation of a polishing particle during storage (excellent in stability for storing). The object is achieved by a metal polishing composition comprising an anionic surfactant having 2 or more anionic functional groups in a molecule, a polishing abrasive, an inorganic salt, and water.
本发明的目的是提供一种金属抛光组合物,它可以高速抛光铜和钽等金属,对疏水性低介电常数膜具有更高的洗涤效率,并且在储存过程中抛光粒子不会沉淀,具有极佳的稳定性(储存稳定性极佳)。本发明的目的是通过一种金属抛光组合物来实现的,该组合物包括分子中含有 2 个或 2 个以上阴离子官能团的阴离子表面活性剂、抛光研磨剂、无机盐和水。
