Nanotechnology


Nanotechnology ( ; NT Nano Technology ) is close to the nanometer scale of one-billionth of a meter atom,molecular techniques for synthesizing materials at small units and the degree of supramolecular and assembly, control, or measurement, identifying its nature Say. Most generalized definitions of nanotechnology have been defined by the National Nanotechnology Initiative (NNI) as a technique for handling materials with sizes ranging from at least 1 to 100 nanometers, and generally between 1 and 100 nanometers in size. The technology for a range of materials or objects is classified as nanotechnology. Nanotechnology is widely used in various fields of science such as Surface Science, Organic Chemistry, Molecular Biology, Semiconductor Physics, and Microfabrication. . Nanotechnology could create new materials and machines with a wide range of applications, such as medicine, electronics, biomaterials energy production and consumer products, but could also cause many problems. Thus, this concern has led to discussions between rights advocacy groups and governments on whether or not special regulations in nanotechnology are justified.

Scanning Probe Technology is the core technology on which nanotechnology is based, and it is a technology that measures and analyzes nanometer-level properties, structures and components. Nano-measuring technology can be classified into X-ray technology, electron / ion beam technology, infraredUltraviolet light and visible light technology based on the type of incident source with the recent SPM  technology . Since nano-measurement technology is huge in scope, it is difficult to analyze and classify search in total. Therefore, in this analysis, the surface shape, structure, and physical and chemical properties of various thin films   relation to the semiconductor industry, where Korea is showing strength compared to other countries, focusing on SPM technology, which is the representative technology of nano measurement technology. It is limited to several nano-measurement techniques that are currently in use or that are expected to increase in the future. Also, as nanotechnology is developed, it will be used in various fields such as chemistry, physics, biology, geography, etc.
