  • Patent number: 8735229
    Abstract: A ZnO-based thin film transistor (TFT) is provided herein. Also provided is a method for manufacturing the TFT. The ZnO-based TFT is very sensitive to the oxygen concentration present in a channel layer. In order to prevent damage to a channel layer of a bottom gate TFT, and to avoid a deep negative threshold voltage resulting from damage to the channel layer, the method for manufacturing the ZnO-based TFT comprises formation of an etch stop layer or a passivation layer comprising unstable or incompletely bonded oxygen, and annealing the layers to induce an interfacial reaction between the oxide layer and the channel layer and to reduce the carrier concentration.
