Photolithography method creates complex patterns using inorganic nanocrystals as colorful inks
Controlling the surface chemistry of inorganic nanocrystals, also known as quantum dots, has enabled researchers to devise a photolithography process for making all-inorganic patterned thin films. Unlike conventional lithography, the new technique requires no polymeric photoresists. The method, which requires fewer steps and could reduce fabrication costs for electronics, has been applied to metal, semiconductor, magnetic, and oxide nanocrystals (Science 2017, DOI: 10.1126/science.aan2958). Conventional lithography provides electronics . . .
