研究目的
Investigating a novel fabrication method for single crystal diamond scanning probes for atomic force microscopy (AFM) using Faraday cage angled etching (FCAE) to overcome limitations of common oxygen-based ICP dry etching processes.
研究成果
The FCAE-based method offers significant advantages over membrane-based technology, including reduced process complexity and cost, and enables the scalable production of high-aspect-ratio diamond scanning probes for various applications.
研究不足
The membrane-based fabrication is lengthy and costly, with challenges in handling fragile diamond membranes. The FCAE approach requires optimization for larger substrates and automated assembly.
