Nanotechnology is an umbrella term that is used to describe a variety of techniques to fabricate materials and devices on the nanoscale. Nanotechnological techniques include those used for fabrication of nanowires, those used in semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining, nanoimprint lithography, atomic layer deposition, molecular vapor deposition, and further including molecular self‐assembly techniques. Applying nanotechnologies raises questions about the environment, health, and societal risks also but that is a huge area of debate. It’s too early to say whether Development of Nanotechnology will prove to be a boon or bane for the coming future.
