Abstract: Disclosed is a method for fabricating a thin film transistor. Specifically, the method uses local oxidation wherein a portion of a transparent metal oxide layer is locally oxidized to be converted into a semiconductor layer so that the oxidized portion of the transparent metal oxide layer can be used as a channel region and the unoxidized portions of the transparent metal oxide layer can be used as source and drain electrodes.The method comprises the steps of forming a gate electrode on a substrate and forming a gate insulating layer thereon, forming a transparent metal oxide layer on the gate insulating layer, forming an oxidation barrier layer on the transparent metal oxide layer in such a manner that a portion of the transparent metal oxide layer positioned over the gate electrode is exposed, and locally oxidizing only the exposed portion of the transparent metal oxide layer to convert the exposed portion into a semiconductor layer.
