Abstract
Owing to the improvement of organic electronics material, organic material can actually be applied to the flexible electronics. Nowadays there is extensive research n different applications of organic electronics, like PLED, OLED, solar cells, e-paper, and RFID tags. Even organic sensors can be produced by organic materials with specific fabrication process. In order to fabricate organic electronics components on flexible substrate solution process is often adopted. In this thesis, combined with opto-mechatronics, an all inkjet printing process based on printing system including piezoelectric print head, liquid/gas control subsystem, drops observation subsystem, positioning subsystem, was developed. With this inkjet printing system and ambient control subsystem, organic thin film transistors can be fabricated successfully by material modifying, surface treatment and thermal modulating . In the fabrication process of this organic thin film transistor, the stability of printing process and the performance of OTFT can be raised by the mbient control system. The performance of transistors can also be improved by changed surface treatment and doped insulator materials.
