Abstract (in Japanese) (See Japanese page) 
(in English) Printing high resolution electrodes is an important technology for realizing the high integration of sensing devices and organic radio-frequency tags as well as for further improving the performance of organic transistors. Reverse-offset printing method can form fine patterns of functional materials such as silver nanoparticles with a submicrometer line spacing at room temperature. However, the silver nanoparticle inks for the reverse-offset printing usually contain organic additives such as dispersive agents and surfactants, which degrade their electric performances. In this research, we aimed at improving the electrical characteristics of the organic transistors with the reverse-offset-printed electrodes by nitrogen plasma treatment. The effect of the plasma irradiation was evaluated by the surface analyses of the electrodes and the measurement of transistor characteristics. By irradiating the plasma on the printed silver electrodes, the mobility in the saturated region was improved from 3.6 × 10^ -3 to 1.1 cm2 / Vs by three orders of magnitude, and the on / off ratio was improved from 10^5 to 10^8.
