We present the organic thin-film transistors (OTFTs) based on the ink-jet printed silver electrodes as the source and drain electrodes. To fabricate the conductive silver electrodes by the low-temperature heat-treatment below 200°C, the inks containing silver nano-particles with the size of about 20 nm were printed on the silicon substrate with a 300 nm-thick SiO2. It was observed that the conductivity of the ink-jet printed lines after heat-treatment at 200°C was similar to that of a bulk silver material. Poly(3,3″ -dialkylquarterthiophene) (PQT-12) was deposited over the printed silver electrodes to fabricate the organic transistor. I-V character was measured to investigate an electrical performance of the fabricated transistor.
