Use Of Spin Coaters In Next-Gen Electronics Circuits

Navson Spin Coaters find use in many scientific labs, research institutes and industrial processes. Like in the deposition of ultrathin polymer films and semiconductor device fabrication. The spin coating method is also extensively used in photolithography for photoresist layers of about 1 micrometer thick. Recently, researchers at MIT have used spin coater to put layers of wax to protect the atom-thin material, Graphene, from performance-impairing wrinkles and contaminants that mar its surface during device fabrication.


Graphene is an atom-thin material that holds promise for making next-generation electronics. Researchers are exploring possibilities for using the exotic material in circuits for flexible electronics and quantum computers, and in a variety of other devices – Source:


Used Spin Coater for Smoothing Wrinkles in Graphene


  1. Graphene, a fragile material
  2. Challenge, while transferring to new substrate
  3. Traditional method introduces defects and impairs performance
  4. Spin coating paraffin and layering it on graphene introduces a protective layer
  5. Paraffin layer when heated, expands and removes wrinkles in graphene layer

Deposit SWCNT On Substrate via Spin Coating Method

The development of a solution-based SWCNT deposition process, which is simple and low-cost, is strongly demanded. The various methods of solution-based SWCNT deposition including spin coating are:

  1. Vacuum filtration (VF)
  2. Spraying
  3. Dip coating
  4. Bar coating
  5. Spin coating




Using Spin Coating For SWCNT Thin Films


Among these methods, the spincoating has been recognized as the most promising process for mass production and industrialization of SWCNT thin films because of the,

  1. Uniformity of the film
  2. Ease of thickness control
  3. Short coating time
  4. Low-temperature fabrication
  5. Highly reproducible


The spin coating process is the most effective method for fabricating the SWCNT thin film, because of the lack of appropriate surfactant for dispersion of SWCNTs in solvent.
