摘要
以化学机械全局平面化(CMP)动力学过程和机理为基础,在抛光浆料中采用粒径为1 5~20nm的硅溶胶作为CMP磨料,保证了高的抛光速率(200nm/min),同时可有效降低表面粗糙度,减少损伤层的厚度。
The smaller size ranging from 15-20nm silica sols is chosen as abrasive, which is based on the investigation of the polishing kinetics process and mechanism of CMP. The polishing slurry with smaller abrasive and polishing technology effectively can reduce the roughness and thickness of the damaged layer and also afford high polishing rate (200nm/min).
