Abstract
We have fabricated organic thin film transistors by thermal lamination process, which is expected as solvent-free, low temperature, continuous and high throughput fabrication process of organic flexible sheet devices. We also tried to apply xerography to make pattern of organic semiconductor toner. Xerography and succeeding thermal lamination will enable us to construct solvent-free printing process. In addition, we evaluated a flexibility of our thin film transistor structure by finite element calculation, and revealed the stress/strain distribution in the device.
