Abstract
In this paper, we present our preliminary results of high aspect ratio 3D PEDOT pillar study by drop-on demand (DOD) direct printing system. Design of the experimental setup and the fabrication of the DOD PEDOT pillar are introduced. Currently, the system can achieve a PEDOT pillar with a height of 300 μm and 80 μm in diameter. The proposed PEDOT 3D printing process has a wide range of potential applications in the eletronics and display industry. © 2012 SPIE.
