Over 1.5 years, conducted 200+ controlled experiments to systematically investigate the relationship between laser parameters, etchant chemistry, and etching precision. Leveraged solutal Marangoni convection phenomena to actively remove bubbles and reaction byproducts, producing clean, sharply defined nanoscale features. The optimized process achieved breakthrough results in feature resolution while dramatically reducing chemical consumption compared to traditional photolithography. Findings were documented, co-authored for publication, and presented at the prestigious Optical Trapping and Optical Micromanipulation XXII conference, with applications spanning electronics, photonics, and biomedical device manufacturing.
