Popis: We developed a high-performance, hydrogenated amorphous silicon thin-film transistor (a-Si:H TFT) on plastic substrate using an organic gate insulator. The TFT with a silicon-nitride (SiN/sub x/) gate insulator exhibited a field-effect mobility of 0.3 cm/sup 2//Vs and a threshold voltage of 5 V. On the other hand, an a-Si:H TFT with an organic gate insulator of BCB (benzocyclobutene) has a field-effect mobility of 0.4 cm/sup 2//Vs and a threshold voltage of 0.7 V. The leakage currents through the gate insulator of an a-Si:H TFT with an organic gate insulator is about two orders of magnitude lower than that of an a-Si:H TFT with a SiN/sub x/ gate insulator.
