Abstract: A conductive material layer for forming a conductive pattern is formed on a substrate. A photosensitive organic material layer is formed on the conductive material layer. The photosensitive organic material layer is irradiated through a halftone mask. The halftone mask includes a first mask region having a boundary corresponding to an edge of the conductive pattern, a second mask region, and a third mask region disposed between the first mask region and the second mask region. A first pattern including a first region corresponding to the first mask region and a second region corresponding to the third mask region is formed by removing the photosensitive organic material layer. The conductive material layer is etched using the first pattern as a hard mask to form the conductive pattern having exposed lateral surfaces. A second pattern is formed that covers the lateral surfaces of the conductive pattern by reflowing the first pattern.

Abstract: A method of manufacturing a thin film transistor and a method of manufacturing a display substrate having the same are disclosed. In one aspect, the method of manufacturing a thin film transistor comprises forming an oxide semiconductor layer over a substrate, plasma-treating the oxide semiconductor layer with a plasma generated from a nitrogen gas or a nitric oxide gas so as to decrease defects in the oxide semiconductor layer, and annealing the plasma-treated oxide semiconductor layer to form a channel layer.
