摘要:
The present disclosure is directed to methods and systems for processing a thin film. An exemplary method can include irradiating a first region of the thin film with a first laser pulse with a first energy density sufficient to partially melt the first region and cause crystal grain lateral growth from a seed region within the first region after the first laser pulse and irradiating the first region of the thin film with at least one sequential laser pulse with a time interval after the first laser pulse and a second energy density sufficient to delay crystal nucleation and extend lateral crystal growth within the first region without partially melting the film.
摘要(中):
本公开涉及用于处理薄膜的方法和系统。 示例性方法可以包括用第一能量密度的第一激光脉冲照射薄膜的第一区域,该第一激光脉冲足以部分地熔化第一区域并在第一激光脉冲之后引起第一区域内的种子区域的晶粒横向生长,以及 用第一激光脉冲之后的时间间隔的至少一个顺序的激光脉冲照射薄膜的第一区域,以及足以延迟晶体成核并延长第一区域内的横向晶体生长而不使膜部分熔化的第二能量密度。
