摘要:
The invention provides a metal polishing liquid comprising an oxidizing agent and colloidal silica in which a part of a surface of the colloidal silica is covered with aluminum atoms, and a Chemical Mechanical Polishing method using the same. An amino acid, a compound having an isothiazoline-3-one skeleton, an organic acid, a passivated film forming agent, a cationic surfactant, a nonionic surfactant, and a water-soluble polymer may be contained. A metal polishing liquid which is used in Chemical Mechanical Polishing in manufacturing of a semiconductor device, attains low dishing of a subject to be polished, and can perform polishing excellent in in-plane uniformity of a surface to be polished.
摘要(中):
本发明提供了一种金属抛光液,其包含氧化剂和胶体二氧化硅,其中胶体二氧化硅的一部分表面被铝原子覆盖,并使用化学机械抛光方法。 可以包含氨基酸,具有异噻唑啉-3-酮骨架的化合物,有机酸,钝化成膜剂,阳离子表面活性剂,非离子表面活性剂和水溶性聚合物。 在半导体装置的制造中使用的化学机械抛光中使用的金属研磨液,能够使被研磨对象的低凹陷,能够进行抛光面的面内均匀性优异的抛光。
