Abstract:
1. A method of crystallizing a semiconductor layer, the method comprising: disposing a mask for crystallizing a semiconductor layer on a substrate having a semiconductor layer formed thereon, wherein the mask comprises: irradiating a first area of the substrate with a laser beam through the mask to enhance crystallinity of a portion of the semiconductor layer, by intermittently moving the mask along the first direction with respect to the substrate and irradiating the substrate through the mask at successive positions of the first area; moving the mask along the second direction with respect to the substrate; and irradiating a second area of the substrate with a laser beam through the mask to enhance crystallinity of a portion of the semiconductor layer, by intermittently moving mask along an inversion direction of the first direction and irradiating the substrate through the mask at successive positions of the second area.
