What are Nano Fabrication Labs?

Nano fabrication labs are specialized facilities designed for the creation and manipulation of materials at the nanometer scale. These labs utilize advanced equipment and techniques to pattern, etch, and build nanoscale structures. They play a critical role in the fields of nanotechnology, materials science, and quantum computing.

What Equipment is Found in a Nano Fabrication Lab?

Nano fabrication labs are equipped with a range of sophisticated instruments. Some of the key equipment includes:

- Electron Beam Lithography (EBL) systems for high-resolution patterning.
- Atomic Force Microscopes (AFM) for imaging and manipulating materials at the nanoscale.
- Scanning Electron Microscopes (SEM) for surface imaging.
- Chemical Vapor Deposition (CVD) systems for thin film deposition.
- Etching systems for material removal.

What Techniques are Used in Nano Fabrication?

Several techniques are employed in nano fabrication labs to construct nanoscale structures:

- Photolithography: A process that uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical photoresist on the substrate.
- Electron Beam Lithography (EBL): Utilizes a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive resist.
- Nanoimprint Lithography (NIL): A method of fabricating nanometer-scale patterns by mechanical deformation of imprint resist and subsequent processes.
- Self-Assembly: A process where molecules spontaneously form ordered structures without human intervention.
