• Most conventional lithography uses a variety of techniques to focus light on a photosensitive film to create 2D patterns. These techniques rely on specialized lenses, electron beams or lasers which are extremely expensive
  • The new technique reduces the cost of nanolithography to the point where it could be done in your garage says Dr. Chih-Hao Chang, an assistant professor of mechanical and aerospace engineering at NC State
  • Researchers use the nanosphere to shape the pattern of light, which gives them the ability to shape the resulting nanostructure in three dimensions without using the expensive equipment required by conventional techniques
