本发明的实施方式
[0034] 为了使本申请的目的、 技术方案及优点更加清楚明白, 以下结合附图及实施例 , 对本申请进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅仅用 以解释本申请, 并不用于限定本申请。
[0035] 需要说明的是, 当元件被称为 "固定于"或"设置于"另一个元件, 它可以直接在 另一个元件上或者间接在该另一个元件上。 当一个元件被称为"连接于 "另一个元 件, 它可以是直接连接到另一个元件或者间接连接至该另一个元件上。
[0036] 还需要说明的是, 本实施例中的左、 右、 上、 下等方位用语, 仅是互为相对概 念或是以产品的正常使用状态为参考的, 而不应该认为是具有限制性的。
[0037] 如图 3所示, 在对显示面板 (如 TFT-LCD液晶面板) 中的玻璃面板 10 ' 进行薄 膜镀膜操作以形成薄膜镀膜层, 即步骤 S1(T , 然后对薄膜镀膜层进行检测以确 定玻璃面板 10 ' 上是否存在缺陷, 即步骤 S20 ' , 如果检测到玻璃面板 10 ' 上存 在缺陷, 则确定该缺陷所在玻璃面板 10 ' 的具体位置。 接着, 如图 1所示, 利用 切割刀具 40 ' 对整块玻璃面板 10 ' 进行切裂成小片 (图 1中所示黑色箭头方向为 切割方向) , 即步骤 S3(T , 从而获取具有缺陷位置 1 的小片玻璃面板利用 FI B设备 20 ' 进行 FIB分析, 并同吋利用扫描电子显微镜进 30 ' 对 FIB分析结果进行 观察, 即步骤 S40 ' , 如图 2所示。 由于目前本领域技术中对玻璃面板 10 ' 进行 的各个操作的机器设备分别分散在各个不同的安装位置, 因而必须将玻璃面板 1 0 / 进行切裂成小片之后才能够进行 FIB分析, 否则, 如果将整块玻璃面板 10 ' 来回搬运, 则不仅造成工作人员劳动量加大, 而且玻璃面板 10 ' 属于易碎危险 品, 容易造成工作人员的身体伤害。 这样的结构就导致必然要切裂玻璃面板 10
' 之后再进行 FIB分析, 从而造成玻璃面板 10 ' 的浪费。
[0038] 为了能够既节省玻璃面板 10的报废浪费, 同吋也能够不增加工作人员的劳动量
, 并且保证工作人员的身体安全, 因此, 本申请提供了一种检测方法。
[0039] 如图 4至图 6所示, 在该检测方法中, 包括以下步骤:
[0040] 检测显示面板中的整块玻璃面板 10是否具有缺陷位置 11 ;
[0041] 在检测获得整块玻璃面板 10上的缺陷位置 11后, 利用第一离子检修装置 20, 即 第一 FIB装置, 利用第一 FIB装置发出的第一束聚焦离子束对玻璃面板 10上的缺 陷位置 11进行切割, 以将缺陷位置 11处的缺陷进行剥离并观察缺陷形貌;
[0042] 然后, 应用修复装置 40, 即 Laser CVD修复装置 (参见解释说明②) , 对剥离 缺陷之后的缺陷位置 11进行修复处理;
[0043] 其中, 检测缺陷位置的检测装置、 第一 FIB设备和 Laser CVD修复装置顺序安装 在同一条检测修复生产线上。
[0044] 通过将检测装置、 第一 FIB设备和 Laser CVD修复装置顺序安装在同一条检测修 复生产线上, 然后对整块玻璃面板 10进行缺陷位置 11的检测确定, 待确定了缺 陷位置 11之后, 由于玻璃面板 10能够在同一条检测修复生产线上紧接着被传送 至下一工序, 因而可以方便地对整块玻璃面板 10上的缺陷位置 11进行 FIB分析、 切割并观察缺陷形貌, 接着在将整块玻璃面板 10传送至 Laser CVD修复装置的修 复工序中进行修复处理。 因此, 应用本申请的技术方案, 能够保留具有缺陷位 置 11的整块玻璃面板 10, 并且能够对玻璃面板 10上的缺陷位置 11进行修复, 使 得整块玻璃面板 10能够被修复成符合产品质量要求的玻璃面板产品, 从而节省 了玻璃面板的报废浪费率, 节省了生产成本, 并且在整个生产过程中, 工作人 员不需对玻璃面板 10进行搬运或接触碰撞, 因而能够在不增加工作人员工作量 的基础上也保护了工作人员的身体安全。
[0045] 如图 4所示, 在检测显示面板中的整块玻璃面板 10是否具有缺陷位置 11之前, 首先完成步骤 S10, 对显示面板中的整块玻璃面板 10进行薄膜镀膜处理以获得薄 膜镀膜层, 其中, 缺陷位置 11处的缺陷为薄膜镀膜层的缺陷。 即, FIB分析、 La ser CVD修复均是对该薄膜镀膜层中的缺陷进行分析以及修复。 在本申请中, 通 过采用真空蒸镀镀膜工艺、 溅射镀膜工艺、 等离子体镀膜工艺、 离子镀膜工艺 中一种镀膜工艺加工形成该薄膜镀膜层; 或者, 通过采用真空蒸镀镀膜工艺、 溅射镀膜工艺、 等离子体镀膜工艺、 离子镀膜工艺中多种镀膜工艺组合加工形 成薄膜镀膜层。
[0046] 如图 4所示, 在对玻璃面板 10上的缺陷位置 11进行检测的过程, 本申请的检测 方法中应用的检测装置为光学检测机器, 优选为应用目前的技术成型且技术成 熟的 AOI机器 (参见解释说明③) , 即利用 AOI机器完成步骤 S20中的检测操作, 也就是 AOI机器通过光学摄像头扫描整块玻璃面板 10以采集图像, 并与 AOI机器 的数据库中存储的合格参数进行比较, 以确定玻璃面板 10上的缺陷位置 11以及 观察缺陷形貌。 通过光学检测原理对玻璃面板 10上可能出现的缺陷位置 11进行 拍照摄像检测, 检测结果直观清楚地显示。
[0047] 或者在图 4所示的步骤 S20中, 本申请的检测方法中所应用的检测装置为第二离 子检修装置, 即第二 FIB装置, 利用第二 FIB设备所发出的第二束聚焦离子束对 显示面板的玻璃面板 10进行扫描显像, 以确定玻璃面板 10上的缺陷位置 11以及 观察缺陷形貌。 利用第二 FIB设备进行扫描显像, 请参见解释说明①。
[0048] 为了在对玻璃面板 10上的缺陷位置 11利用第一 FIB设备的聚焦离子束进行剥离 缺陷吋能够确保玻璃面板 10不会被剥离过度, 因此, 在对缺陷位置的缺陷进行 剥离的过程中, 即对玻璃面板 10上的缺陷位置进行如图 4所示的步骤 S30过程中 , 同吋利用扫描电子显微镜对进行剥离的缺陷位置进行观察, 以实吋判断剥离 结果是否符合后续的 Laser CVD修复的要求 (此吋, 该扫描电子显微镜仅仅针对 该剥离过程进行监控, 并且该扫描电子显微镜与第一 FIB设备并排且固定设置)
[0049] 在判断玻璃面板 10上的缺陷位置 11的剥离程度已经符合 Laser CVD修复的要求 吋候, 则停止第一 FIB设备工作, 然后将玻璃面板 10传送至下一修复工序的工位 处利用 Laser CVD修复装置对剥离完成的缺陷位置 11进行修复, 使得修复后的玻 璃面板 10能够符合玻璃面板产品质量要求, 即是完成如图 4所示的步骤 S40的 Lase r CVD修复操作。 在对显示面板的缺陷位置进行修复的过程中, 同样需要对缺陷 位置的修复过程进行实吋监测, 从而实吋地监控显示面板的缺陷位置的修复操 作过程, 防止在针对缺陷位置进行修复操作的过程出现操作失误而导致显示面 板报废。 为此, 通用应用扫描电子显微镜对显示面板的缺陷位置在修复过程中 进行实吋监控, 该用于对修复过程进行实吋监控的扫描电子显微镜与对剥离过 程进行实吋监控的扫描电子显微镜为同一个显微镜, 此吋该扫描电子显微镜是 能够移动地安装在第一离子检修装置 20与修复装置 40之间。 当对显示面板的缺 陷位置进行剥离操作吋, 该扫描电子显微镜移动至与第一离子检修装置 20并排 设置, 从而对整个剥离操作过程进行实吋监控; 当对显示面板的缺陷位置进行 修复操作吋, 该扫描电子显微镜移动至与修复装置 40并排设置, 从而对个修复 操作过程进行实吋监控。
[0050] 在另一可行的实施方式中, 为了提高生产效率, 因而扫描电子显微镜设置了两 个。 其中一个扫描电子显微镜用于在对显示面板的缺陷位置进行剥离的过程中 对剥离操作过程进行实吋监控, 该扫描电子显微镜与第一离子检修装置 20并排 且固定设置; 另一个扫描电子显微镜用于在对显示面板的缺陷位置进行修复的 过程中对修复操作过程进行实吋监控, 该扫描电子显微镜与修复装置并排且固 定设置。 这样, 就能够改进、 解决仅设置一个扫描电子显微镜先后对剥离操作 进行监控、 对修复操作进行监控的等待问题, 使得每个工作工位均具有相对的 独立性。
[0051] 在本申请中, 在应用修复装置对剥离缺陷之后的缺陷位置进行修复处理完成之 后, 且在将显示面板进行后续的黄光制程工艺之前, 对修复完成的显示面板进 行修复质量检测并判定显示面板的修复质量是否合格, 对修复质量合格的显示 面板进行后续的黄光制程工艺, 对修复质量不合格的显示面板进行返工重新修 复处理或者做报废处理。 从而确保进入后续黄光制程工艺工序的显示面板的质 量完全符合产品合格要求, 确保所生产制作并且最后出货的显示面板的质量满 足质量要求。
[0052] 具体地, 在完成应用 Laser CVD修复装置对剥离缺陷之后的缺陷位置进行修复 处理之后, 再将显示面板进行后续的黄光制程工艺 (该黄光制程工艺的实施过 程与目前本领域应用的黄光制程工艺的实施过程相一致, 因而在此不再赘述)
, 也就是进行图 4所示的步骤 S50操作, 以继续完成对显示面板的生产加工。 [0053] 根据本申请的另一方面, 提供了一种检测设备, 如图 5和图 6所示。 该检测设备 应用于上述的检测方法中, 对显示面板中的玻璃面板 10上的缺陷进行检测并修 复。 该检测设备包括检测装置、 第一离子检修装置 20 (即第一 FIB装置, 参见解 释说明①) 和修复装置 40 (即 Laser CVD修复装置) , 检测装置用于检测显示面 板中的玻璃面板 10上的缺陷位置 11, 第一 FIB设备用于切割显示面板的缺陷位置 11, Laser CVD修复装置用于对显示面板的切割完成后的缺陷位置 11进行修复, 并且, 检测装置、 第一 FIB设备及 Laser CVD修复装置顺序地安装在同一条生产 线上。
[0054] 通过将检测装置、 第一离子检修装置 20 (即第一 FIB装置) 和修复装置 40 (即 L aser CVD修复装置) 顺序安装在同一条检测修复生产线上, 然后对整块玻璃面 板 10进行缺陷位置 11的检测确定, 待确定了缺陷位置 11之后, 由于玻璃面板 10 能够在同一条检测修复生产线上紧接着被传送至下一工序, 因而可以方便地对 整块玻璃面板 10上的缺陷位置 11进行 FIB分析、 切割并观察缺陷形貌, 接着在将 整块玻璃面板 10传送至 Laser CVD修复装置的修复工位中进行修复处理。
[0055] 在本实施例中, 检测装置可以选择现今普遍通用的 AOI机器 (即光学检测机器 ) , AOI机器通过光学摄像头扫描整块玻璃面板 10以采集图像, 并与 AOI机器的 数据库中合格参数进行比较, 以确定玻璃面板 10上的缺陷位置 11以及观察缺陷 形貌。 通过光学检测原理对玻璃面板 10上可能出现的缺陷位置 11进行拍照摄像 检测, 检测结果直观清楚地显示。
[0056] 或者, 检测装置还可以使用第二离子检修装置 (即第二 FIB装置, 参见解释说 明①) , 利用第二 FIB设备进行扫描显像。
[0057] 进一步地, 检测设备还包括用于对显示面板的缺陷位置的剥离过程进行观察的 一个扫描电子显微镜, 扫描电子显微镜与第一离子检修装置 20 (即第一 FIB装置 ) 并排设置 (并且, 此吋该扫描电子显微镜是与第一离子检修装置 20并排且固 定设置, 即第一离子检修装置 20与该扫描电子显微镜之间的相对位置固定, 该 扫描电子显微镜仅用于对剥离操作过程进行实吋监控) 。 在对缺陷位置的缺陷 进行剥离的过程中, 同吋利用扫描电子显微镜对进行剥离的缺陷位置进行观察 , 以实吋判断剥离结果是否符合后续的 Laser CVD修复的要求。 [0058] 或者, 在另一可行的实施方式中, 检测设备中设置的一个扫描电子显微镜是能 够移动地设置在第一离子检修装置 20与修复装置 40之间。 此吋, 能够应用该扫 描电子显微镜对同一块显示面板的剥离操作过程、 修复操作过程按照加工工序 顺序进行先后的同步实吋监控, 即当对显示面板的缺陷位置进行剥离操作吋, 该扫描电子显微镜移动至与第一离子检修装置 20并排设置, 从而对整个剥离操 作过程进行实吋监控; 当对显示面板的缺陷位置进行修复操作吋, 该扫描电子 显微镜移动至与修复装置 40并排设置, 从而对个修复操作过程进行实吋监控。
[0059] 或者, 在另一可行的实施方式中, 检测设备中设置了两个扫描电子显微镜。 其 中一个扫描电子显微镜与第一离子检修装置 20并排且固定设置 (第一离子检修 装置 20与该扫描电子显微镜之间的相对位置固定) , 此扫描电子显微镜仅针对 第一离子检修装置 20对显示面板的缺陷位置进行的剥离操作进行实吋监控; 另 一个扫描电子显微镜与修复装置 40并排且固定设置 (修复装置 40与该扫描电子 显微镜之间的相对位置固定) , 此扫描电子显微镜仅针对修复装置 40对显示面 板的缺陷位置进行的修复操作进行实吋监控。
[0060] 为了能够更加凸显出显示面板中的玻璃面板 10上的缺陷位置 11, 因而检测设备 还包括薄膜镀膜装置, 薄膜镀膜装置设置在检测装置的上游位置, 该薄膜镀膜 装置可以是进行真空蒸镀镀膜工艺、 溅射镀膜工艺、 等离子体镀膜工艺、 离子 镀膜工艺中的一种镀膜工艺的设备, 或者薄膜镀膜装置可以是进行真空蒸镀镀 膜工艺、 溅射镀膜工艺、 等离子体镀膜工艺、 离子镀膜工艺中多种镀膜工艺组 合实施的设备。 通过在检测装置进行检测之前对玻璃面板 10进行镀膜, 使得缺 陷位置 11更加突出地显示, 在进行检测吋候能够更容易地发现缺陷位置 11, 防 止出现漏检、 错检的情况发生。
[0061] 在对显示面板进行修复完成之后, 需要将显示面板继续输往后续的黄光制程工 艺设备中进行相应的黄光制程工艺, 为了能够保证修复完成并进入黄光制程工 艺加工工序的显示面板均满足修复质量要求, 因此, 检测设备还包括用于对切 割完成后的缺陷位置修复完成的显示面板进行修复质量检测的修复质量检测装 置, 该修复质量检测装置设置在修复装置 40的下游位置, 并且位于后续的黄光 制程工艺设备的上游位置, 即修复质量检测装置设置在修复装置 40与后续的黄 光制程工艺设备之间的位置处。 优选地, 修复质量检测装置为第三离子检修装 置, 即第三 FIB装置 (参见解释说明①) 。
[0062] 解释说明:
[0063] ① FIB: Focused Ion Beam, 是将液态金属 Ga离子源产生的离子束经过离子枪加 速, 聚焦后照射于样品表面产生二次电子信号取得电子像, 此功能与 SEM (扫 描电子显微镜) 相似; 或用强电流离子束对表面原子进行剥离, 以完成微、 纳 米级表面形貌加工, 通常是以物理溅射的方式搭配化学气体反应, 有选择性的 剥除金属、 氧化硅层或沉积金属层。
[0064] ©Laser CVD: 激光化学气相沉积, 反应是由激光激发的化学气相沉积方法。
[0065] ③ AOI: Automatic Optic Inspection, 自动光学检测, 是基于光学原理来对待检 测器件中的缺陷进行检测、 定位的设备, 当自动检测吋, AOI机器通过摄像头自 动扫描待检测器件, 采集图像, 将所获得的图像数据与数据库中的合格参数进 行比较, 经过图像处理, 检査出缺陷位置, 并通过显示器或自动标志把缺陷位 置显示或标示出来, 供维修人员进行后续修整。
[0066] ④真空蒸镀: 在真空环境中, 将材料加热并镀到基片上称为真空蒸镀, 金属加 热至蒸发温度, 然后蒸汽从真空室转移, 在低温零件上凝结, 该工艺在真空中 进行, 金属蒸汽到达表面不会氧化。
[0067] ⑤溅射镀膜: 溅射镀膜是指在真空条件下, 利用获得功能的粒子轰击靶材料表 面, 使靶材表面原子获得足够的能量而逃逸的过程称为溅射。 被溅射的靶材沉 积到基材表面, 就称作溅射镀膜。 溅射镀膜中的入射离子, 一般采用辉光放电 获得, 所以溅射出来的粒子在飞向基体过程中, 易和真空室中的气体分子发生 碰撞, 使运动方向随机, 沉积的膜易于均匀。 发展起来的规模性磁控溅射镀膜 , 沉积速率较高, 工艺重复性好。
[0068] ⑥等离子体镀膜: 这里指的是 PVD领域通常采用的冷阴极电弧蒸发, 以固体镀 料作为阴极, 采用水冷、 使冷阴极表面形成许多亮斑, 即阴极弧斑。 弧斑就是 电弧在阴极附近的弧根。 在极小空间的电流密度极高, 弧斑尺寸极小, 估计约 为 1μηι〜100μιη, 电流密度高达 105A/cm 2— 107 A/cm 2。 每个弧斑存在极短吋间, 爆发性地蒸发离化阴极改正点处的镀料, 蒸发离化后的金属离子, 在阴极表面 也会产生新的弧斑, 许多弧斑不断产生和消失, 所以又称多弧蒸发。 最早设计 的等离子体加速器型多弧蒸发离化源, 是在阴极背后配置磁场, 使蒸发后的离 子获得霍尔 (hall) 加速效应, 有利于离子增大能量轰击量体, 采用这种电弧蒸 发离化源镀膜, 离化率较高, 所以又称为电弧等离子体镀膜。
[0069] ⑦离子镀膜: 又称离子镀, 是采用某种方法 (如电子束蒸发磁控溅射, 或多弧 蒸发离化等) 使中性粒子电离成离子和电子, 在基体上必须施加负偏压, 从而 使离子对基体产生轰击, 适当降低负偏压后, 使离子进而沉积于基体成膜。 离 子镀的优点如下: (1) 膜层和基体结合力强; (2) 膜层均匀, 致密; (3) 在 负偏压作用下绕镀性好; (4) 无污染; (5) 多种基体材料均适合于离子镀。
[0070] 以上仅为本申请的较佳实施例而已, 并不用以限制本申请, 凡在本申请的精神 和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本申请的保护范 围之内。
