Abstract:
1. A method for fabricating a thin film transistor (TFT), comprising: forming a gate on a substrate; forming a gate insulating layer on the substrate to cover the gate; forming a metal oxide material layer on the gate insulating layer; forming a photoresist layer on the metal oxide material layer, wherein a thickness of the photoresist layer above the gate is larger than that of the photoresist layer above two sides adjacent to the gate; removing a portion of the metal oxide material layer to form a metal oxide active layer by using the photoresist layer as a mask; removing the photoresist layer above the two sides adjacent to the gate while leaving the photoresist layer covered on a portion of the metal oxide active layer; and forming a source and a drain on the metal oxide active layer covered by the photoresist layer.
