Abstract for Presentation
Humidity Effect on electrical performance of solution-processed In2O3 thin film transistor
Solution-processed thin film transistor (TFT) based on metal oxide shows great potential in the next-generation display technology . During the conventional sol-gel process, the relative humidity (RH) during the coating process has great impact on the quality of thin film and the device properties . However, the effect of RH in storage environment on the electrical performance of the TFTs is rarely studied. In addition, the RH is critical for the semiconductor manufacturing and device packaging, it is also necessary to keep the RH constant in moisture-sensitive environments (such as cleaning rooms and glove boxes). In this work, solution-processed indium oxide (In2O3) TFT is fabricated, and the electrical performance of the device is investigated after being exposed to various RH conditions. It is found that the electrical performance of the In2O3 TFT exhibits clear response to the RH variation (Figure 1). The inherent mechanism about the humidity effect on the electrical performance is elaborated, this is due to the “donor effect” from the absorbed water molecules . It is believed that this work provides guidance for the oxide TFT applied in flat display industries.
