Description

本发明涉及显示技术领域, 尤其涉及一种阵列基板的防静电结构。 背景技术
液晶显示装置 ( Liquid Crystal Display, LCD )具有机身薄、 省电、 无 辐射等众多优点, 得到了广泛的应用。 现有巿场上的液晶显示装置大部分 为背光型液晶显示装置, 其包括壳体、 设于壳体内的液晶显示面板及设于 壳体内并相对液晶显示面板设置的背光模组 ( backlight module ) 。 液晶显 示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子, 并在两玻 璃基板上施加驱动电压来控制液晶分子的旋转, 从而将背光模组的光线折 射出来产生画面
静电 ( Electro Static discharge , ESD )在半导体生产行业一直是一个 悬而未决的问题, 静电会导致产品良率降低、 成本增加、 产能下降。 在液 晶显示装置制造工艺中, 静电也一直影响着液晶显示装置的品质, 尤其是 液晶显示面板的生产工艺。
静电的产生主要分为三大因素:
一是颗粒(particle ) , 任何一种颗粒都有可能造成器件损伤, 甚至产 品报废, 因此半导体制造工艺中, 管控颗粒是一项重要的工作。
二是工程条件和原材料, 在液晶显示面板工艺制程中, 沉积
( deposition ) 工序、 曝光 ( hoto ) 工序、 t虫刻 ( etch ) 工序、 剥离 ( strip ) 以及清洁 (dean ) 工序等的工艺条件都会产生静电, 同时, 在该 些制程中所用到的原材料由于材料缺陷也会产生静电。
三是 ¾计因素, 产品设计的好坏直接影响了静电的情况。
为了提高产品品质, 降低生产成本, 在液晶显示面板的生产工艺会进 行静电防护工作。 该静电防护工作包括两大类: 一是液晶显示面板内部器 件保护, 主要是在液晶显示面板的线路(柵极(Gate ) 线和数据 (Data ) 线) 的始末端设计防静电环 (ESD ring ) ; 二是液晶显示面板外围电路保 护, 主要是保护阵列制程以及后端制程中静电对面板外围电路的损伤。 在 现有的 TFT阵列基板结构中, 膜层顺序为: 第一金属层 (Gate/Com ) —櫥 绝缘层 ( GI ) —有源层 ( Aetive ) —第二金属层 ( S/D ) —钝化层 ( PVX ) —透明导电层 (Indium Tin Oxides , ITO ) , 为了控制产品的成 本, 通常在成盒(CeU )段制程完成切割 (cutting ) 以后进行点灯判级, 进而将合格的液晶显示面板(panei )投入模组。 为了实现在 Ceil段制程能 够点灯, 同时又不影响模组段的正常点灯, 通常会在阵列基板制作过程 中, 在液晶显示面板的外围图案 (patterning )上一些电路, 即设置短路棒 ( shorting bar ) 100, 从而减少静电释放现象, 如图 1所示, 液晶显示面板 在 Cell段制程点灯判级以后, 会采用激光镭射的方式将短路棒 100与数据 线(Data线)和栅极线(Gate线) 的端子断开。 但该技术在液晶显示面板 的绝缘保护层和有源层的千法蚀刻工艺中, 等离子体(piasma )异常放电 仍会对短路棒 100处金属交叠走线造成静电损伤, 影响产品品质。 发明内 ^
本发明的目的在于提供一种阵列基板的防静电结构, 在阵列基板制造 过程中, 尤其是对绝缘保护层和有源层进行千法蚀刻时, 可以很好地避免 交叠走线造成的静电损伤, 提高产品品
