  • Method of crystallizing silicon film and method of manufacturing thin film transistor liquid crystal display
    Patent number: 7205184
    Abstract: A method of crystallizing a silicon film by which it is possible to obtain a polycrystalline silicon thin film having a uniform crystal structure and a good quality, and a method of manufacturing a thin film transistor-liquid crystal display (TFT-LCD) using the same. In the method of crystallizing the silicon film, an amorphous silicon film is formed on a substrate and a reflective film pattern is formed on the amorphous silicon film. The silicon film is crystallized by irradiating a laser onto the amorphous silicon film. The reflective film pattern is formed to expose the channel of the thin film transistor in the amorphous silicon film.
