摘要

一种新的混合抛光工艺,即双盘化学辅助磁流变抛光(DDCAMRF)工艺,已被开发用于单晶硅片的抛光,该工艺结合了化学机械抛光(CMP)和磁流变抛光(MRF)两种工艺的优点。在目前的工作中,硅原子间的结合力因化学作用而减弱,从而进一步软化了工作表面,而磁流变液体的旋转则提供了所需的机械力,有助于从工作表面去除材料。为了实现硅基底的纳米精加工,我们设计并制造了一套混合精加工实验装置。此外,还通过实验研究进一步确定了该工艺,包括分析不同工艺因素(即抛光速度、CIP 浓度百分比、浆料流速和工作间隙)对单晶硅晶片表面粗糙度(Ra)的影响。在使用所开发的 DDCAMRF 工艺进行抛光时,硅晶片的表面粗糙度提高了 88.96%以上,并获得了近乎镜面的光洁度。与现有的各种抛光技术相比,所开发的工艺提高了工艺性能,确保了更好的表面光洁度(即缺陷最小),并缩短了抛光时间。

Experimental Investigation into Double-disc and Chemically Assisted Magnetorheological Finishing Process

A new hybrid finishing process, namely, double-disc chemical-assisted magnetorheological finishing (DDCAMRF) process has been developed for the polishing of monocrystalline silicon wafers combining the benefits of the two processes namely, chemical–mechanical polishing (CMP) and magneto-rheological finishing (MRF). In the present work, the bonding between the Si atoms gets weakened by the chemical action which further softens the work surface while the rotation of MR fluid provides the desired mechanical force which assists in the removal of material from the work surface. An experimental setup for the hybrid finishing has been designed and fabricated for achieving the nanometric finishing of silicon substrates. Also, the process was further established by carrying out the experimental study which involves analyzing the influence of different process factors viz., polishing speed, % CIP concentration, slurry flow rate, and working gap, on the surface roughness (Ra) of a monocrystalline silicon wafer. An improvement of over 88.96% was observed in the surface roughness of a silicon wafer and a nearly mirror-like finish was observed while carrying out the polishing with the developed DDCAMRF process. The developed process resulted in enhancing the process performance ensuring better surface finish (i.e., with minimal defects) and reduced polishing time compared to different polishing techniques available.
