摘要
对ULSI制备中铜布线化学机械抛光(CMP)进行了分析,综述了铜CMP技术的研究现状.主要内容包括铜CMP去除机理、铜CMP抛光液;分析了目前铜CMP技术存在的问题,指出了铜CMP今后的研究重点.
The copper chemical mechanical polishing (CMP) which is the key planarization technology for ULSI manufacturing was discussed, and the progress and problems of CMP were reviewed in the paper. The material removal mechanisms and the slurry of copper CMP were analyzed especially. The emphases of the future research were also pointed out.
