Nanolithography

Nanolithography

Nanolithography which is a branch of nanotechnology deals with the study and application of fabrication of nanoscale structures like semiconductor circuits.

It is used in the fabrication of leading-edge semiconductor integrated circuits (nanocircuitry) or nanoelectromechanical systems (NEMS).Small structures (nm) can be synthesized by Nanolithogaphy. Extreme ultraviolet lithography is capable of using light at wavelength of 13.5nm.

In dip-pen nanolithography small tip is used to deposit molecules on a surface which can achieve very small sizes, but cannot currently go below 40nm.

Electron-beam lithography is much more expensive and time consuming than photolithography, It (few minutes) functions more like a dot-matrix printer than a flash-photograph (5 Hous).
