Abstract
We have fabricated pentacene field-effect transistors (FETs) on polyimide-sheet films with polyimide gate dielectric layers and parylene encapsulation layer, and investigated the high-temperature performance. It is found that the mobility of encapsulated FETs is enhanced from 0.5 to 0.8 cm2/Vs when the device is heated from room temperature to 160°C under light-shielding nitrogen environment. Furthermore, after the removal of annealing temperatures up to 160°C, the transistor characteristic of mobility and on/off current ratio show no significant changes, demonstration the excellent thermal stability of the present organic FETs.
