Highly conductive ink-jet-printed lines

Abstract

Printing techniques, such as ink-jet printing, screen printing, and flexography, are promising alternatives to conventional photolithography for the production of electronic devices. The advantages of these techniques include low manufacturing costs, environmental sustainability, manufacturing simplicity, and high material usage. Among these techniques, ink-jet printing is particularly advantageous because it is a noncontact, maskless process with drop-on-demand and scale-up feasibilities. Therefore, ink-jet printing is currently used to fully or partially fabricate advanced electronic devices. In this chapter, we introduce some ink-jet printing technologies to improve the electrical conductivity of printed lines.
