摘要：

We have studied the fabrication of stable organic thin-film transistor (OTFT) for plastic electronics using hybrid multi-layer (HML) of parylene/Au/photoacryl/IZO (indium zinc oxide) on organic semiconductor. The HML-passivated OTFTs exhibited the field-effect mobility (mu(fe)) of 0.2-0.3 cm(2)/V s with an on/off current ratio of 10(7) after annealing at 180 degrees C. The changes in on-, off- and subthreshold-currents of the HML-passivated OTFT were negligibly small during the storage of 781 h. Moreover, the hysteresis in transfer characteristics was negligible even after exposure of the OTFT to air for 781 h. These results indicate that HML-passivation is suitable for stable OTFT array for plastic electronics. (c) 2008 Elsevier B.V. All rights reserved.
