    • An apparatus for supplying a solution to a substrate includes a nozzle unit. The nozzle unit may include at least one nozzle having a variable structure in which lateral portions of the at least one nozzle are bent toward a central portion of the at least one nozzle. Each nozzle of the nozzle unit may include a hinged connecting member disposed at the central portion of each of the nozzles. The hinge angles between lateral portions of each of the nozzles may vary during operation. Each of the nozzles may include a plurality of spray holes for uniformly providing a developing solution onto the photoresist film. Some of the plurality of holes positioned near the central portion of the nozzles may be substantially wider than some of the plurality of holes positioned near lateral portions of the nozzles.
    • 用于将溶液供给到基板的装置包括喷嘴单元。 喷嘴单元可以包括具有可变结构的至少一个喷嘴,其中至少一个喷嘴的侧向部分朝向至少一个喷嘴的中心部分弯曲。 喷嘴单元的每个喷嘴可以包括设置在每个喷嘴的中心部分处的铰接连接构件。 每个喷嘴的横向部分之间的铰链角度可以在操作期间变化。 每个喷嘴可以包括用于均匀地将显影溶液提供到光致抗蚀剂膜上的多个喷射孔。 位于喷嘴的中心部分附近的多个孔中的一些孔可以比位于喷嘴的侧面部分附近的多个孔中的一些孔大得多。
