Recent Advances in Eco-friendly Nano-ink Technology for Display and Semiconductor Application

Printing technologies have been indicated as alternative methods for patterning conductive, semi-conductive or insulative materials on account of their low-cost, large-area patternability and pattern flexibility. For application of the printing technologies in manufacture of semiconductor or display modules, ink or paste composed of nanoparticles, solvent and additives are basically needed. Here, we report recent advances in eco-friendly nano-ink technology for semiconductor and display technology. Then, we will introduce an eco-friendly ink formation technology developed in our group with an example of manufacturing nanopowders and inks. We tried to manufacture ultrafine nanoparticles by applying a low-temperature synthetic method, and then attempted to fabricate the printed film onto the glass substrate to see whether the nanoparticles are feasible for the printing or not. Finally, the electrical characteristics of the films were measured to investigate the effect of the manufacturing parameters.
