以氧化铝磨料在化学机械抛光中的应用为例,研究了抛光液组成、pH值、磨料粒度及其浓度、分散剂和氧化剂、抛光平台和载体的转速以及抛光压力等因素对碳化硅晶体衬底(0001)Si和(0001)C表面材料去除速率的影响。本文的研究结果将为碳化硅晶体衬底化学机械抛光浆料的研制、工艺参数的优化以及材料去除机理的研究提供参考。
The influences of the polishing slurry composition, such as the pH value, the abrasive size and its concentration, the dispersant and the oxidants, the rotational velocity of the polishing platen and the carrier and the polishing pressure, on the material removal rate of SiC crystal substrate (0001) Si and a (0001) C surface have been studied based on the alumina abrasive in chemical mechanical polishing (CMP). The results proposed by our research here will provide a reference for developing the slurry, optimizing the process parameters, and investigating the material removal mechanism in the CMP of SiC crystal substrate.
