In the process of studying the composition of matter, scientists have found that several or dozens of countable atoms or molecules separated on the nanometer scale obviously show many new characteristics, and the technology of manufacturing equipment with specific functions by using these characteristics is called nanotechnology.
Nano-science and technology is based on many modern advanced science and technology, and it is the product of the combination of modern science (chaotic physics, quantum mechanics, mesoscopic physics, molecular biology) and modern technology (computer technology, microelectronics and scanning tunneling microscope technology, nuclear analysis technology).
Nano-science and technology will trigger a series of new science and technology, such as nano-physics, nano-biology, nano-chemistry, nano-electronics, nano-processing technology and nano-metrology.

The main differences between nanotechnology and microelectronics.
Nanotechnology studies how to control a single atom and molecule to realize the specific function of equipment, which works by using the fluctuation of electrons. Microelectronics technology mainly realizes its function by controlling the population of electrons and works by using the particle nature of electrons. The purpose of people's research and development of nanotechnology is to achieve effective control of the entire micro-world.
Nanotechnology is a comprehensive subject with strong cross-cutting, and its research content involves the vast field of modern science and technology. From 65438 to 0993, the International Steering Committee of Nanotechnology divided nanotechnology into six sub-disciplines: nanoelectronics, nanophysics, nanochemistry, nanobiology, nanofabrication and nanometrology.
Among them, nano-physics and nano-chemistry are the theoretical basis of nano-technology, and nano-electronics is the most important content of nano-technology.
