Fabrication of Nanowires

• Several fabrication processes of silicon nanowires have been developed in the research community. They can be divided into bottom-up or top-down approaches. This chapter describes top-down fabrication of silicon nanowires using electron beam lithography (EBL), which combined with optical lithography can be a viable approach if not too many silicon nanowires need to be patterned on a wafer. It also describes the sidewall transfer lithography (STL) technique using I-line stepper lithography to pattern a vast amount of silicon nanowires on a silicon wafer. In addition the chapter examines how bottom-up Si nanowires synthesized by vapor-liquid-solid (VLS)-chemical vapor deposition (CVD) can be assembled at low cost in an efficient way for further use as a sensing material. Among the solution-based assembly methods for the nanostructured network (nanonet) fabrication, the vacuum filtration method is highly simple, versatile, low cost and scalable to large areas.
