Keywords – Nanoelectronics, Synthesis of nanostructure, Electronic and ion lithographic, thin tapes, Micro- mechanisms INTRODUCTION Nanoelectronics is leading direction in nanotechnology development. Informational technologies based on application of nanoelectronic communication systems, information processing and registration systems, intellectual manu- facturing processes, transport, medical and everyday devises and systems control develop rapidly. Solving of energetic and ecological problems requires manufacturing of new catalysts, gas absorbers and separators, molecular nets, electrodes and membranes for new renewable energy sources and transformers and its control with the help of nanoelectronic devices saturated with nanoelectronic elements, sensors and mechanisms that will be more and more useful. It is very important that considerable resources, thought out organization of personnel education, organization of scientific researches and introduction of results into manufacture are necessary for nanotechnology development. WHAT NANOTECHNOLOGY AND NANOSCIENCE ARE? Nanotechnology should be called totality of getting functional elements, systems and nanomaterials with dimensions of separate components that can be compared with molecule dimensions that are equal 100-200 nanometers methods. Nanoscience studies processes that flow in very small nanodevices with visualization and measuring, with computer modeling of the processes, with control of manipulation of separate atoms and molecules. Introduction into manufacture of nanosized components and systems is also very important. There are two main methods of nanocomponents and structures creation: ɚ) from bottom to the top with application of separate atoms manipulation or by using their natural tendency to group in clusters that is very important in creating nanomaterials and b) top-down mainly after application and perfection of methods developed for manufacturing submicron electronic elements and systems. It should be mentioned that only combination of these two methods can solve problems of nanotechnology. STAGES OF NANTECHNOLOGY DEVELOPMENT 80s of 20 th century are known to be the beginning of nanotechnology development. In these years several discoveries and achievements of scientists from different countries took Nobel award: such as R. Carl and H. Krotto (1996) for synthesis in 1985 from carbon atoms of nano- structure called fullerene; B.G. Binning and H. Roher in Zurich created scanning tunnel microscope (STM, AFM); Holland and Britain physicists observe stairs on vault-ampere characteristics of point contact (1987) approving effect of quantum conductivity; T.A. Fulton and G.J. Dolan in Bell laboratory construct one-electron transistor and observe coulomb blocking; scientists from USA, France and Germany discover effect called giant magneto-conductivity at the same time (1984-1987); Sumio Ijima (1991) attracted world interest to carbon nanotubes that he developed; in 80s and 90s main results in electronic and ion lithography field were published; at the same time role of molecule self organization on metal surfaces started to increase; since 1996 some state agencies in USA have started researches of world tendency of nanoresearches and nanoworks for industry and researches of recommendation to USA government to exceed resources integrated in this field. SOME FEATURES OF THE MATERIALS THAT WERE GOT WITH APPLICATION OF NANOTECHNOLOGIES For material to get new properties and gtt new applications appropriate nanostructure must be synthesized. It is connected to typical length, correspondent to each material feature. For example, electric resistance of the following material is result of dispersion of electron flow situated in conductive zone, due to the hits with vibrating atoms of the material and its admixtures. These acts of dispersion characterize by length called free run (or dispersion length). When device length becomes comparative to one or another characteristic length (most of them are situated in nanodimensional field) physical and chemistry of this effect changes. Moving power of nanotechnology is search of nanomaterials with structure and features that differs from big characteristics of materials (what is actual for most materials) and creation of devices based on nanodimensional components created on the base on regularity that is actual in nano-world. It is forecasted that the fastest development will be: nanoelectronics and devices connected to information technologies; technologies that collect and effectively transform energy; biotechnologies that increase quality of life and technologies that improves ecology and not on the last place – nanotechnologies. 1 1784, Bulgaria, Sofia, Bulgarian AS institute of electronics; 2 03065, Ukraine, Kyiv, Peremogy avenue 37, National technical university of Ukraine “KPI”
