Facile photo-patterning of electrodes using a direct photo-patternable polyimide for organic thin-film transistors |
| 초록 |
Organic electronics based on organic thin-film transistors (OTFTs) have been extensively studied because they are applicable to low-cost, large-area and flexible electronics. We report a facile and cost-effective process for the photo-patterning of the electrodes. Photo-sensitive polyimide (PSPI) was used to obtain patterned source and drain electrodes in OTFTs, instead of conventional photoresist. PSPI with cinnamate moieties could be crosslinked by UV-light exposure without any photoinitiator. After the photo-patterning process of this work, gold/PSPI bilayer electrodes were easily prepared and they were successfully used as source and drain electrodes of the pentacene OTFT. |
