| 摘 要： | 利用电化学、接触角、化学机械抛光等试验研究一种新型环保的铜缓蚀剂聚乙烯吡咯烷酮(polyvinyl pyrrolidone，PVP)的效果。结果表明:PVP在铜化学机械抛光中具有一剂多用的效果，将其与另一种环保弱缓蚀剂1, 2, 4-三氮唑(1, 2, 4-triazole，TAZ)混合使用，既能保证平坦化效果，又能实现工业生产所需的低压高去除率抛光，在粗糙度为2.28 nm时, 去除率达到1 291 nm/min。

| Abstract: | This study uses electrochemical, contact angle, chemical mechanical polishing and other experiments to study the effect of a new environmentally friendly potential copper corrosion inhibitor polyvinyl pyrrolidone(PVP). Experiment results show that PVP has a multi-purpose effect in copper chemical mechanical polishing. That mixing it with another environmentally friendly weak corrosion inhibitor TAZ ensures the flattening effect and environmental protection properties, and can achieve large removal of low pressure in industrial production. When the roughness is 2.28 nm, the removal rate can reach to 1 291 nm/min. |
