Latest Patents

Chit Yiu Chan holds a patent for the "Fabrication of single crystal diamond tips and their arrays." This invention addresses the generation of sharp single crystal diamond tips and their arrays, utilizing a unique fabrication technology. The process combines the deposition of synthetic diamond films with reactive etching techniques. By preparing diamond orientation and creating a reactive etching environment with directed ions, Chan is able to fabricate single crystal diamond tips with varying apical angles. The resulting diamond tips exhibit an apical angle of no more than about 28° and a tip radius smaller than 50 nm. This novel method allows for the formation of diamond tip arrays over large areas with remarkable uniformity and high reproducibility.
