Abstract

In this work, depletion-mode transistors were made of InZnO thin filmsprepared and grown on transparent conductive substrates by DC sputteringtechnique. The SiO2-In2O3-ZnO system and N2 plasma incorporated InZnOfilm were grown to get a better controllability of the carrier concentrationduring the film growth. Hydrogen plasma and oxygen plasma effects on the TCO films and the TFTs were investigated. Devices were simulated in a device model to extract the parasitic parameters. The depletion-mode TFTs have been fabricated successfully on glass by using InZnO films as the channel layers.
