Nanofabrication is the process of creating structures and devices with dimensions in the nanometer scale (1-100 nanometers). It involves manipulating atoms and molecules to build structures that are smaller than the wavelength of visible light. Nanofabrication is a crucial technology for the development of nanotechnology and has a wide range of applications in fields such as electronics, medicine, energy, and materials science. One of the most important techniques used in nanofabrication is lithography, which involves the transfer of patterns from a mask onto a substrate. Lithography is used to create complex patterns of features on a surface with nanometer-scale resolution. There are several different types of lithography techniques, including optical lithography, electron beam lithography, and nanoimprint lithography [1].

In addition to lithography, other techniques used in nanofabrication include molecular beam epitaxy, chemical vapour deposition, and atomic layer deposition. These techniques allow researchers to deposit or remove atoms or molecules one at a time, enabling the precise manipulation of materials at the nanoscale. One of the most exciting applications of nanofabrication is in the development of nanoelectronics. As conventional silicon-based electronics reach their physical limits, researchers are exploring the potential of new materials and devices that operate at the nanoscale. For example, carbon nanotubes and graphene have unique electrical and mechanical properties that make them promising materials for future electronics.

Nanofabrication is also being used to develop new materials with unique properties. For example, researchers are using nanofabrication techniques to create materials with ultra-high strength, flexibility, and conductivity. These materials have potential applications in fields such as aerospace, energy, and medicine. In the field of medicine, nanofabrication is being used to create devices and systems for drug delivery, biosensing, and tissue engineering. For example, researchers are using nanofabrication techniques to create scaffolds for tissue engineering that mimic the structure of natural tissues. These scaffolds can be used to repair damaged tissues or organs [2].

One of the critical advances in nanofabrication is the use of nanolithography, which involves the creation of patterns on a substrate at the nanoscale. Nanolithography has enabled the production of smaller and more complex devices, including transistors, sensors, and photonic devices. Another critical advance in nanofabrication is the use of self-assembly, a process that occurs spontaneously when certain molecules are mixed together. Self-assembly can be used to create complex structures and patterns, such as photonic crystals, that would be challenging to achieve through traditional fabrication methods [3].

In addition to these techniques, researchers are exploring the use of biomolecules, such as DNA and proteins, as building blocks for nanofabrication. DNA nanotechnology, for example, involves using DNA molecules as programmable templates to create precise structures and devices at the nanoscale. Nanofabrication has numerous applications in various fields, including electronics, energy, and medicine. In electronics, nanofabrication has led to the development of smaller, faster, and more efficient devices. For example, the development of nanotransistors has enabled the production of smaller and more powerful computer chips [4].

Nanofabrication is a rapidly advancing field that is enabling the precise manipulation of materials at the nanoscale. With its wide range of applications, nanofabrication has the potential to revolutionize fields such as electronics, medicine, energy, and materials science. As researchers continue to develop new techniques and materials, the possibilities for nanofabrication are endless. It also has important implications for the environment and sustainability. By enabling the development of new materials and devices, nanofabrication can help reduce waste, energy consumption, and carbon emissions [5].
