Bottom-contact organic transistors with carbon-paste electrodes are fabricated by means of the surface selective deposition technique, where a carbon-paste solution is deposited on the region in which the self-assembled monolayers are removed by ultraviolet light irradiation. The resulting bottom-contact pentacene transistor realizes high performance of 1.0 cm2 V-1 s-1. The present method is applied to solution-processed polythiophene transistors as well as n-channel materials.
