Purpose: Enabling nanofabrication techniques as tools for experiments to understand the underlying science and engineering in the nanometer scale are required. This paper is a resume a range of technology and characterization tools relevant for nanoelectronics devices. Design/methodology/approach: An overview on bottom - up and bottom - down fabrication techniques are presented in this paper. As an alternative to the continually increasing cost of nanotechnology for manufacturing electronic devices, new strategies are examined in research, which are based on basic principles of physics and chemistry. For example, molecular self-organization mechanisms are developed in order to manufacture well-defined nanostructures with desired properties. Findings: This paper includes description of three methods of production nanolayers and monolayers molecular self-organization, Langmuir-Blodget films and Nanoimprint Litography. Research limitations/implications: The most extreme approach is to build nanostructures atom by atom with the help of scanning tunneling microscope at low temperatures. This is very slow method to build nanostructures, usually a couple of hours. An alternative approach for the formation of nanostructures is self-organization of atoms. Practical implications: The greatest advantage of litographic patterning is very large variety of different structures which can be defined by lithographic methods, Langmuir - Blodget (LB) films is another unpopular method to produce nanomaterials. Originality/value: Materials engineering technology stands today at the edge of a huge challenge: produce cheap nanomaterials for nanoelectronics. Building materials from the bottom up requires a multidisciplinary approach. This arena is unquestionably in the nano-dimension, where all fields of science and engineering meet.
