Abstract

Nowadays the electronic industry companies is working as much as possible to use printing techniques to produce function devices. Function devices may be electronic component, integrated circuits, solar cells or OFET. Function printing means printing clean structures and clean surfaces with highest precision.The major challenge that exits today to use of flexography printing technology to produce function devices and in the identification, characterisation and optimization of the printed structures and surfaces. Flexography is characterized by flexible and elastic printing plates, they are characterised by a topological difference between printing and nonprinting areas. This research aims to investigate the effect of using flexographic printing plates to print of source/drain electrode structure as one of component of OFET and the basic challenge for the circuit fabrication is the morphology and topography of the source/drain electrode structure. As a result of an experimental study, it has been proven that the flexographic digital plates are used to print thinner lines of  source/drain structures in compared with the other types of plates. The lower value of surface roughness were with Nyloflex plate and the flexographic digital plate so they are suitable to print electronics to get smooth layers. For printed electronics, it's very important to print thick film to ensure good conductivity of ink so it must use anilox rolls have rough screen rulings and big cells depths. The occurrence of “viscous fingering" can be avoided by optimization of the ink formulation (e.g. viscosity and surface tension).
