Organic Thin-Film Transistors with Ink-jet Printed Metal Electrodes
Abstract:Ink-jet printing technology is widely used in numerous applications. Various inks are developed for the demand of electronic devices. Ink-jet printing conductive metal nanopastes have been used in printed circuit boards and passive components. This technique provides a manufacturing method that can replace more expensive process such as lithography or metal evaporation. In this paper, we demonstrate a new method for manufacturing conductive electrodes of organic thin-film transistors (OTFTs). Adjusting ink properties and jetting performance can control the qualities of the printed nanopaste film. Curing temperature and time are also the key issues which are required for the better morphology of the film. Soluble conjugated polymers such as poly 3-hexylthiophene (P3HT) are very promising candidates for a cheap electronic device on various substrates and suitable for the applications of ink-jet printing technology. We compare the characteristics of OTFTs for the evaporated and the ink-jet printed source-drain electrodes. This approach presents a simple method for fabricating OTFT device and is suitable for a flexible display displays and circuits.
