    摘要: Disclosed is a method for forming a polycrystalline silicon film by crystallizing an amorphous silicon film. A mask has first to third shot regions having the same length. The first to third shot regions have transmission sections and non-transmission sections, which are alternately aligned. The transmission sections of the first shot region are positioned corresponding to the non-transmission sections of the second shot region, the non-transmission sections of the first shot region are positioned corresponding to the transmission sections of the second shot region, and the transmission sections of the third shot region are aligned corresponding to center portions of the transmission sections of the first and second shot regions. Primary to nth laser irradiation processes are performed with respect to the glass substrate, thereby crystallizing the amorphous silicon film into the polycrystalline silicon film.

    摘要: A ZnO-based thin film transistor (TFT) is provided herein. Also provided is a method for manufacturing the TFT. The ZnO-based TFT is very sensitive to the oxygen concentration present in a channel layer. In order to prevent damage to a channel layer of a bottom gate TFT, and to avoid a deep negative threshold voltage resulting from damage to the channel layer, the method for manufacturing the ZnO-based TFT comprises formation of an etch stop layer or a passivation layer comprising unstable or incompletely bonded oxygen, and annealing the layers to induce an interfacial reaction between the oxide layer and the channel layer and to reduce the carrier concentration.
