发明名称 Cleaning solution for semiconductor surfaces following chemical-mechanical polishing
摘要 A composition and method are provided for cleaning contaminants from the surface of a semiconductor wafer after the wafer has been chemically-mechanically polished. The cleaning composition comprises a carboxylic acid, an amine-containing compound, a phosphonic acid, and water. The cleaning composition is useful in removing abrasive remnants as well as metal contaminants from the surface of a semiconductor wafer following chemical-mechanical polishing.
