A method for manufacturing a thin film transistor (TFT) is disclosed. The method is achieved by forming and defining a source and a drain of a thin film transistor through two lithographic processes cycles so that the channel length (L) of the thin film transistor can be reduced to 1.5 to 4.0 μm. Besides, the Ion current of the thin film transistor is increased as the channel length (L) is decreased. Therefore, the component area of the thin film transistor is decreased as the channel width (W) is decreased. Thus, the aperture ratio of the TFT-LCD can be increased due to the decreased component area of the thin film transistor. |
