Abstract:
PURPOSE: A method for manufacturing the gate insulating film and the gate electrode of a thin film transistor is provided to cost effectively perform manufacturing processes using a self-aligning effect. CONSTITUTION: An active layer(130) is formed on a substrate including a source electrode and a drain electrode. A polysilane thin film is formed on the active layer using a liquid manufacturing process. A gate metal layer is formed on the polysilane thin film. The polysilane thin film is converted into a gate insulating film(140') by radiating ultraviolet ray toward the lower side of the substrate. The polysilane thin film is eliminated excluding the converted gate insulating film through a thermal treatment process. The gate metal layer is patterned to form a gate electrode(150').
