| Outline of Final Research Achievements |
The basic technology development for realization of high-frequency operating organic-transistor circuits leaded to the following achievement. Surface treatment for contact electrodes and optimization of fabrication process realized a high mobility of 3.3 cm2/Vs in organic transistors with bottom contact configuration that is easily applied to short channel transistors. Also, threshold voltage control in the range of a few V was demonstrated by oxygen plasma treatment. Furthermore, the work function and the thermal stability of surface-modified electrodes for low contact resistance were investigated. As a result, work functions in the range of 4.3 to 5.5 eV were obtained.
