Abstract
We report the spreading currents in a-IGZO and its application to TFT and TFT circuit designs. To confirm the spreading currents in oxide TFTs. we made stripe-patterned S/D electrodes. It is confirmed that the drain currents are same between the conventional and stripe patterned oxide TFTs. The stripe pattern can significantly reduce the overlap capacitance between gate and source/drain electrodes without degrading the drain currents. This leads to increase the speed of the TFT circuits and improve the high current stability and mechanical flexibility.
