| 摘 要： | 以超大规模集成电路(ULSI)芯片多层互连结构制造中的关键平坦化工艺——铜化学机械抛光(Cu—CMP)为研究对象，针对Cu—CMP中存在的抛光液的化学腐蚀作用和磨料的机械磨损现象，采用腐蚀磨损理论分析了Cu—CMP材料去除机理。提出铜CMP的材料去除中存在着机械增强的化学腐蚀和化学增强的机械磨损，并分析了Cu—CMP的静态腐蚀材料去除、机械增强的腐蚀去除与化学增强的机械去除机理。

| Abstract: | Copper chemical-mechanical polishing which is the key planarization process in multi-layer mental interaction of ultra-scale-integrated circuits(ULSI) manufacturing was studied.According to the existed phenomenon of the chemical corrosion of slurry chemistry and the abrasive impact of mechanical abrasive,the material removal mechanism of Cu-CMP was analyzed by the corrosive wear theory.It was pointed that the enhancement of corrosive wear of slurry chemistry by mechanical effects and the augmentation of abrasive wear by corrosion of slurry should exist in the material removal process.The static etching of slurry,the enhancement of corrosive wear of slurry chemistry by mechanical effects and the augmentation of abrasive wear by corrosion of slurry were analyzed. |

| Keywords: | ULSI Copper CMP material removal mechanism corrosive wear |
