1. the top-down method used in traditional small-scale manufacturing equipment while being limited by the resolution of these methods will allow the large level of control structures that occur. Typically, a thin-film devices fabricated from metal or a semiconductor layer etching.2. the method below depending on the contrary use of single molecular chemical property that would cause the single-molecule component manually assembled into some useful format. These methods use the concept of molecular assembly manual and/or accepted at the molecular level, this allows the production of very small structures, although often at the expense of limited control of the production process.3. a combination of these methods may be used, in which Nano-molecular level will be included in a top-down framework.

1. How top-to-use, small traditional manufacturing equipment, while being limited by the resolution of these methods will allow a large degree of control over the resulting structure. Typically, the devices fabricated from thin metal film or semiconductor layer carved
two. The bottom-up approach, in contrast to the chemistry of a single molecule to cause the component molecules self-assemble into some useful form. These methods use the concept of molecular self assembly and / or accepted at the molecular level. This enables the production of very small structures, although often at the expense of the limited control of the manufacturing process
3. The combination of these methods may be used in nanoscale molecules which are included in the box top to bottom.
