摘要: A CMP semiconductor wafer planarization method is provided employing an aqueous solution of a trialkanol amine as a wafer cleaning solution. Wafers are produced exhibiting a substantial reduction in semiconductor device failures as shown by a significant decrease in m.sub.1- m.sub.1 (metal to metal) shorts.
