    • PURPOSE: A method for manufacturing a thin film, a semiconductor thin film, a semiconductor device, a method for manufacturing a semiconductors thin film, and a system for manufacturing a semiconductor thin film are provided to manufacture a thin film, especially a semiconductor thin film, in which volatile gases, e.g. hydrogen, in a thin film can be reduced just like a case employing an electric furnace without sacrifice of productivity while preventing breakage of the film. CONSTITUTION: A thin film(2) containing volatile gas is irradiated with excimer laser light(5) having pulse width of 60 nS or longer thus degassing the thin film. The thin film(2) can be protected against breakage even if it is re-crystallized subsequently and short time processing is realized by excimer laser irradiation. Alternatively, a thin film containing 2 atm.% or more of volatile gas is irradiated with excimer laser having pulse width of 60 nS or longer thus degassing the thin film(2) while crystallizing. Since nuclei are formed uniformly, size of crystal particles is made uniform and variations of characteristics are suppressed.
    • 目的:提供一种薄膜制造方法,半导体薄膜,半导体装置,半导体薄膜的制造方法以及半导体薄膜的制造方法,制造薄膜,特别是半导体薄膜 ,其中挥发性气体,例如 可以像使用电炉的情况一样减少薄膜中的氢,而不牺牲生产率而防止膜的破裂。 构成:用脉冲宽度为60nS以上的准分子激光(5)照射含有挥发性气体的薄膜(2),使薄膜脱气。 即使再次结晶化,也可以通过准分子激光照射来实现短时间的处理,可以防止薄膜(2)的破损。 或者,用脉冲宽度为60nS以上的准分子激光器照射含有2质量%以上的挥发性气体的薄膜,同时结晶而使薄膜(2)脱气。 由于均匀地形成核,所以使结晶粒子的尺寸均匀,抑制了特性的变化。
