摘要 针对常见的低k介质材料分析了其化学机械全局平坦化的机理,并进一步探讨了低k介质化学机械抛光中包括压力、磨料、pH值和温度在内的几个因素对于抛光速率和表面状态等方面的影响。 The tric material is perature in the rate and surface chemical-mechanical global planarization mechanism to the common low& dielecanalyzed. The effect of several factors including pressure, abrasive, pH and temchemical-mechanical polishing process of low& dielectric material on the polishing appearance are discussed.
