Abstract

The device characteristics of Ti-InSnO thin film transistors (TFTs) with modulated channels were investigated. The field effect mobility was enhanced to 14.9 cm2/V s in the channel-modulated TFT. The electrical performance of the TFT device was improved by the insertion of a high carrier concentration layer at the channel/gate insulator and channel/electrode interfaces. It was due to the enhancement of carrier accumulation and the reduction of parasitic resistance via channel modulation. The threshold voltage was controlled at moderate value. These results indicate that the device characteristic of TFTs can be enhanced by the modulated channel structure.
