Abstract:
1. A crystallization method comprising: providing a substrate having an amorphous silicon layer, wherein the substrate has first and second sides opposing each other; and irradiating a laser beam onto the substrate so as to have an inclined angle with respect to the first and second sides of the substrate; and relatively moving one of the laser beam and the substrate with respect to the other i) in a first direction from the first side to the second side of the substrate and ii) in a second direction which crosses the first direction, wherein the laser beam has a first end and a second end opposing each other and formed along the second direction, wherein the substrate has third and fourth sides each substantially perpendicularly connected to the first and second sides, wherein the third side has a lower end, wherein the fourth side has an upper end, and wherein the lower end and upper end of the substrate are substantially diagonally arranged with respect to each other, wherein when the laser beam is irradiated toward the first side of the substrate, the first end of the laser beam coincides with the lower end of the substrate, wherein when the laser beam is irradiated toward the second side of the substrate, the second end of the laser beam coincides with the upper end of the substrate, and wherein the substrate and the laser beam are relatively moved in the first and second directions in succession.
