Realization of Nano-Wires in Quartz using Focused Ion Beam and ICP/RIE Etching Process for Single Electron Transistor Fabrication

The fabrication of sub-50 nm features with existing lithographic techniques is a technological challenge. Here we present the results for a fabricated nano-structure in quartz which can be potentially used for the large scale fabrication of single electron transistor (SET) devices using ultra-violet nano-imprint lithography (UV-NIL). The fabrication process was developed using focused ion beam (FIB) etching and inductively coupled plasma reactive ion etching (ICP/RIE). The results demonstrate the realization of quartz stamp with required nano-structures for the mass production of SET devices. SET devices could be integrated into nano-scaled systems incorporating vital functions like nano-sensing, data storage and communication will provide revolutionary capabilities.
