The thin film transistor is formed on the substrate and includes a semiconductor layer, a gate electrode, a source electrode, and a drain electrode. The pixel electrode is electrically connected to the thin film transistor and is formed on the same layer as the source electrode and the drain electrode. The source electrode and the drain electrode include a first conductive layer, and the pixel electrode includes a first conductive layer and a second conductive layer stacked thereon.
Abstract:
Embodiments relate to halftone masks that can uniformly form the height of an underlying layer in two regions that are spaced apart from each other, a manufacturing method thereof, and a method for forming a film using the same. The halftone mask includes a first light blocking unit and a second light blocking unit, and a semi-transmitting unit that is disposed adjacent to the side of the second light blocking unit. The first and second light blocking units block light and are spaced apart from each other at a predetermined interval. The semi-transmitting unit is positioned at a side far from the first light blocking unit and reduces intensity of light. Sum of the second length of the second light blocking unit and the third length of the semi-transmitting unit is larger than the first length of the first blocking unit.

The present invention provides a method for fabricating thin film transistor comprising the steps of preparing an insulation substrate; forming an amorphous silicon layer on the substrate; forming a capping layer having 1.78 to 1.90 of the refraction index on the amorphous silicon layer; forming a metal catalyst layer on the capping layer; and crystallizing the amorphous silicon layer into a polycrystalline silicon layer by heat treating the substrate. Therefore, a method for fabricating thin film transistor fabricates a thin film transistor which has superior characteristics and is capable of controlling the characteristics by controlling the refraction index of capping layer formed of nitride film to 1.78 to 1.90 when performing crystallization by super grain silicon crystallization method, thereby obtaining a semiconductor layer having a large grain size so that electron mobility is increased, and an amount of metal catalyst remained is decreased to lower leakage current, and controlling grain size of polycrystalline silicon layer by the refraction index of the capping layer so that a polycrystalline silicon layer having desired size and uniformity is obtained.
