  • Patent number: 7205033
    Abstract: Disclosed is a method for forming a polycrystalline silicon film of a polycrystalline silicon thin film transistor. The method includes a step of crystallizing an amorphous silicon film deposited on a glass substrate by irradiating a laser beam onto the amorphous silicon film using a mask pattern. The glass substrate is horizontally moved by a predetermined distance unit corresponding to a translation distance of the mask pattern when the laser beam is irradiated onto the amorphous silicon film through a mask having the mask pattern, thereby growing grains in a circular shape.

  • Patent number: 7033915
    Abstract: Disclosed is a method for crystallizing a single crystalline Si film on an amorphous substrate, such as a glass substrate or a plastic substrate. The method includes the steps of selectively irradiating the laser beam onto a pixel section TFT forming region and a peripheral circuit TFT forming region of the amorphous silicon film through primary and secondary laser irradiation processes, thereby forming a poly-silicon film and irradiating the laser beam onto one of grains formed in the poly-silicon film through a third laser irradiation process, thereby forming a single crystalline silicon region having a desired size on a predetermined portion of the amorphous silicon film. The amorphous silicon film is locally crystallized into the single crystalline silicon film so that characteristics of TFTs for the pixel section and the peripheral circuit are improved while ensuring high uniformity.
