| Outline of Final Research Achievements |
For realizing high-performance organic TFTs, characteristic properties of organic materials that is unfeasible in the inorganic materials should be utilized. From this view point, this work is conducted to develop fabrication processes of high-performance organic TFTs by using a gate insulating film with molecular alignment capability. From the work, I mainly obtained the following two conclusions;
(1) When using a gate insulating film with vertical molecular alignment capability in organic TFTs, a good performance of an organic TFT is obtained by using a gate insulating film having a weak interaction with organic semiconductor molecules. (2) When using a gate insulating film with parallel molecular alignment capability in organic TFTs, a good performance of an organic TFT is obtained by using a gate insulating film having a strong interaction with organic semiconductor molecules and by selecting a proper alignment direction of the organic molecules.
