The field of nanotechnology has been rapidly advancing over the past few decades, and one of the key areas of research and development has been in the realm of nano fabrication. Nano fabrication refers to the process of creating and manipulating materials at the nanoscale, which is typically defined as being between 1-100 nanometers in size. This technology has the potential to revolutionize the way we manufacture goods, and it is being explored for a wide range of applications, including electronics, medicine, energy, and more.
What is Nano Fabrication?
Nano fabrication is the process of creating and manipulating materials at the nanoscale. This can involve a range of techniques, including lithography, etching, and deposition. Lithography involves using light to create patterns on a surface, while etching involves using chemicals to remove material from a surface. Deposition involves adding material to a surface, and it can be used to create complex structures and patterns.
Advanced Nano Fabrication Techniques
There are several advanced nano fabrication techniques that are being developed and used today. One of the most common techniques is electron beam lithography, which uses a focused beam of electrons to create patterns on a surface. This technique is capable of creating features as small as 10 nanometers in size, making it ideal for applications such as semiconductor manufacturing.
Another advanced nano fabrication technique is nanoimprint lithography, which involves using a mold to create patterns on a surface. This technique is capable of creating features as small as 20 nanometers in size, and it is being explored for applications such as data storage and optical devices.
