| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, from the point of view of energy-saving and low cost, fabrication method for electronic devices by using solution process is attracting much attention. We reported the simple pattering method using printable electrode such as silver nanoparticles ink, which was patterned by the difference of hydrophilic and hydrophobic properties of the surface . In this method, since oxygen plasma was employed for pattering process for the hydrophilic and hydrophobic surface, about 50 µm channel length could be obtained. In this study, to obtain shorter channel length (less than 10 μm), we have developed new fine pattering method for silver nanoparticle ink using hydrophobic photoresist, which have high water contact angle of more than 90. The photoresist layer can be patterned precisely by using ultraviolet (UV) curing through photo masks. After pattering the hydrophobic photoresist using photolithography, silver nanoparticle ink was spin-coated on the patterned substrate. Silver nanoparticle ink was spontaneously patterned along the hydrophilic pattern. As a result, very short channel electrode (less than 10 µm) was successfully achieved by simple spin-coating process. By applying this method to the organic thin-film transistors, we obtained mobility of 0.03 cm^2/Vs and on/off ratio of 10^6. | |
