M.Sc THESIS SPECIALISATION
"Nanopillars and vertical silicon nanowires fabrication using silicon plasma etching processes in room temperature. "
This work demonstrates the fabrication of high aspect ratio silicon nanopillars, perpendicular to the substrate nanowires using room temperature plasma etching. Two fluorocarbon, fluorine, oxygen plasma etching processes are being presented: A) A mixed process and B) a pulsed gas flow process for nanoscale plasma etching (NPGF). Nanopillars, Nanowires with 74:1 aspect ratio, and etch rate 1.8 μm/min were fabricated using ΝPGF process. With the mixed gas process we fabricated nanopillars with an aspect ratio 4:1 and etch rate 250 nm/min.
