Description

一种阵列基板制备方法 技术领域
本发明涉及显示技术领域,尤其涉及一种阵列基板制备方法。
背景技术
目前的阵列基板的制作采用目前常用的Cu barrier(铜阻挡)层,铜是非常容易向其他材料扩散的,在硅和二氧化硅中都有很高的扩散率,这种高扩散率将破坏器件的性能,如果不加隔离,会导致器件中各处都扩散有铜离子,会导致器件有重金属沾污,也会导致钝化层的可靠性下降。因此在长铜之前,要先溅射一层导电的隔离层。铜长好之后,铜和铜连接的地方的隔离层就没办法去掉了,所以就留在了结构中。barrier的目的是为了隔离Cu和其他材料之间的扩散。
Cu barrier层中的MoTi/Ti都存在Tail(拖尾)问题,主要是由Cu和barrier的蚀刻速率差异造成。Tail一方面会影响CD(Critical Dimension,中文简称:临界尺寸)精度、寄生电容及发生短路,另一方面因tail很薄可透光,界面处的折射及反射会造成漏光。
综上所述,现有技术的阵列基板制备方法,由于铜和阻挡层的蚀刻速率差异,导致阻挡层的金属产生拖尾,不仅影响CD精度、寄生电容及发生短路,还造成漏光。故,有必要提供一种新的阵列基板制备方法来改善这一缺陷。
