    • PURPOSE: A crystallization method is provided to obtain a single crystalline layer of a desired size at a desired position from an amorphous layer or a polycrystalline layer by using a laser irradiation method. CONSTITUTION: A laser beam(630) of a particular pattern is irradiated on a substrate of a predetermined size by using a mask. The first crystallization process is performed to crystallize the irradiated part of the substrate. The first scan process is performed to grow grains within the first crystalline part of the substrate. A polycrystalline island region(610) is formed by completing the first scan process. The second scan process is performed to form the grains as a single crystalline region by using the grains as seeds. The single crystalline region is extended by irradiating the laser beam.
    • 目的:提供一种结晶方法,通过使用激光照射方法从非晶层或多晶层在期望的位置获得所需尺寸的单一结晶层。 构成:通过使用掩模将特定图案的激光束(630)照射在预定尺寸的基板上。 进行第一结晶处理以使基板的照射部分结晶。 执行第一扫描处理以在基底的第一结晶部分内生长晶粒。 通过完成第一扫描处理形成多晶岛区域(610)。 通过使用谷物作为种子,执行第二扫描处理以形成作为单一结晶区域的晶粒。 通过照射激光束来延伸单晶区域。
