  • 本研究探討以三種方法對單晶鑽石基板進行拋光的性能表現,包括使用鑽石拋光盤進行拋光、採用膠體二氧化矽(colloidal silica)的拋光以及結合芬頓反應的拋光。研究目標為降低表面粗糙度,同時盡量減少次表層損傷。為了評估拋光前後的表面品質,本研究使用原子力顯微鏡(AFM)、掃描式電子顯微鏡(SEM)與拉曼光譜等技術進行分析。實驗結果顯示,加入芬頓反應的CMP方法能提供最佳的平滑效果,是一種高效率且低損傷的鑽石表面拋光方式,因此具有應用潛力。

    This study investigates the polishing performance of single-crystal diamond substrates using three methods: mechanical polishing with a diamond disk, chemical mechanical polishing (CMP) with colloidal silica, and CMP enhanced with a Fenton reaction. The goal is to reduce surface roughness while minimizing subsurface damage. Surface characterization techniques such as atomic force microscopy (AFM), scanning electron microscopy (SEM), and Raman Spectroscopy were employed to evaluate surface quality before and after polishing. The results show that the Fenton-assisted CMP provides superior smoothing effects, offering an efficient and damage-reducing alternative for diamond surface finishing.
