对于固体薄膜厚度的测试, 目前普遍使用的测试方法主要包括探针法和 光学法两大类。 探针法的原理是利用力学敏感的探针沿着样品表面划过, 记 录表面的形貌, 从而测出薄膜厚度; 光学法是利用光的干涉或衍射来测出薄 膜厚度。 其中, 光学法的适用范围较窄, 若样品表面不平整或样品表面镀有 多种膜层, 光学法的测试精度会受到很大的影响, 而探针法几乎适用于各种 情况的样品表面, 并且测试精度较高, 故而相对于光学法而言具有更广泛的 应用范围。
在使用探针法之前, 需要将镀制了薄膜的样品上的薄膜的一部分去除, 暴露出一部分基板, 使得基板表面和薄膜表面之前形成一定的厚度差异, 通 常这一步骤可称为台阶制备。 现有的台阶制备方法主要有化学腐蚀法和掩膜 法两种。 化学腐蚀法往往会在腐蚀界面上造成一个有一定坡度的腐蚀台阶, 影响到测试精度; 掩膜法适用于大多数的台阶制备工艺, 但是要制作合适的 细窄的或者带有细窄凹槽的掩膜材料, 每次镀膜都要用新的掩膜材料, 成本 高而且不环保。 所以, 现在需要一种测试精度高并且成本较低的方法来测试 薄膜的厚度。 发明内容

具体实施方式 下面将结合描述本发明实施例的附图, 对本发明实施例中的技术方案进 行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不 是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出 创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
实施例一
本发明的该实施例提供一种薄膜厚度的测试方法, 如图 1所示, 该方法 包括:
步骤 S101、将测试掩膜覆盖在基板的表面上, 所述测试掩膜具有多个镂 空部;
如图 2a所示,测试掩膜 2应紧密地覆盖在基板 1的表面上, 为保证高的 测试精度做基础。
例如,可以通过利用紫外线固化胶等粘接剂,将所述测试掩膜 2紧密地、 无空隙地贴附在所述基板 1的表面上。
在本发明的实施例中, 待测厚度的薄膜是镀敷在基板 1上的。 例如, 可 通过溅射镀膜将薄膜敷在基板 1上。 在进行溅射! ¾ 时, 至少需要在基板上 与镂空部对应的位置处形成待测薄膜。 为此, 可以仅在镂空部溅射 当 然也可以在基板的整个范围内! 同样也会在基板上与镂空部对应的位置 处形成薄膜。 为了提高通过溅射镀上的薄膜 4的优良性, 有时候在溅射镀膜 时, 在基板 1的需要 莫的一面上设置筒状的悬浮掩膜 5, 如图 3所示。 可 以利用该悬浮掩膜 5与基板 1之间的作用力, 使得悬浮掩膜 5与基板 1共同 压制住测试掩膜 2的边缘, 提高测试掩膜 2与基板 1的紧密程度。
通常, 基板 1的边缘是不需要溅射镀膜的, 可在基板 1的边缘上包裹一 层掩膜, 此处可称为防着板, 以防止基板 1的边缘被溅射 I¾ 。 此时, 测试 掩膜 2可放置在基板 1和防着板之间, 可进一步提高测试掩膜 2与基板 1之 间的紧密程度。 一般的, 如图 4所示, 所述测试掩膜 2上具有的镂空部的形状、 位置、 大小等性质均可任意设置, 例如, 可设置为正方形等正多边形、 圓形或不规 则形状, 本发明的技术方案对此不做具体限制。
步骤 S102、 对所述覆盖有测试掩膜的基板进行溅射镀膜;
所谓 "溅射" 是指荷能粒子轰击固体表面 (如本说明书附图 2b中的靶材
3)、 使固体原子 (或分子)从表面射出的现象。 如图 2b所示, 由于靶材 3位于 覆盖有测试掩膜 2的基板 1的对面, 射出的固体原子(或分子)可均匀覆盖 在测试掩膜 2以及测试掩膜 2的镂空部分处的基板 1上, 形成一层薄膜 4, 此即为溅射! 通常这一层薄膜 4的厚度为纳米级别甚至更薄。
步骤 S103、 移除所述测试掩膜, 利用探针法进行测量;
如图 2c所示,移除测试掩膜 2后,覆盖在测试掩膜 2表面的薄膜 4同时 被移除, 基板 1上由于测试掩膜 2具有的镂空部而暴露在外的部分上覆盖了 薄膜 4, 而被测试掩膜 2其余部分遮挡的基板 1则保持 莫前的状态, 则测 试掩膜 2移除后, 基板 1上形成了所谓的台阶, 此时可利用探针法对 莫的 厚度进行测量。
由于测试掩膜 2可连同覆盖于其上的薄膜 4一起被直接移除, 所以会使 得基板 1上由测试掩膜 2的镂空部分形成的薄膜 4具有清晰的边缘, 形成明 显的台阶。 同时, 该基板 1表面上有多处可选择测试厚度的区域, 技术人员 在探针测试时, 可任意选择测试位置, 测试点数的分布也可自行决定, 同时 测试膜厚的均一性范围较大, 测试精度高; 并且该覆盖有薄膜 4的测试掩膜 2在经过清洁处理后, 可多次重复使用, 与现有的掩膜法相比, 无需每次使 用新的掩膜材料, 成本低且环保。
通常, 测试掩膜 2的材质可根据实际使用情况选用, 常用的测试掩膜 2 的材质包括金属、 金属氧化物、 陶瓷、 玻璃等。
在本实施例的技术方案中, 提供了一种薄膜厚度的测试方法, 该方法制 得的待测的薄膜的边缘清晰, 台阶明显, 并且基板表面上有多处可选择测试 厚度的区域, 技术人员在使用探针测试时, 可任意选择测试位置, 测试点数 分布也可自行决定, 同时测试膜厚均一性范围较大, 测试精度高; 并且该覆 盖有薄膜的测试掩膜在经过清洁处理后, 可多次重复使用, 与现有的掩膜法 相比, 无需每次使用新的掩膜材料, 成本低且环保。 实施例二
本发明的该实施例提供一种薄膜厚度的测试装置, 该装置包括图 4所示 的测试掩膜 2 , 所述测试掩膜 2具有多个镂空部, 当需要测试薄膜厚度时, 将所述测试掩膜 2覆盖在基板的表面上。
其中, 所述测试掩膜 2具有多个镂空部, 如图 4所示, 所述测试掩膜 2 上具有的镂空部的形状、 位置、 大小等性质均可任意设置, 例如, 可设置为 正方形等正多边形、 圓形或不规则形状,本发明的技术方案对此不进行限制。
如图 2a所示,在需要测试薄膜厚度时,测试掩膜 2应紧密地覆盖在基板 1的表面上, 为保证高的测试精度tt础。
例如,可以通过利用紫外线固化胶等粘接剂,将所述测试掩膜 2紧密地、 无空隙地贴附在所述基板 1的表面上。
在本发明的实施例中, 待测厚度的薄膜是镀敷在基板 1上的。 例如, 可 通过溅射镀膜将薄膜敷在基板 1上。 为了提高通过溅射镀上的薄膜 4的优良 性, 有时候在溅射 莫时, 在基板 1的需要 莫的一面上设置筒状的悬浮掩 膜 5 , 可以利用该悬浮掩膜 5与基板 1之间的作用力, 如图 3所示, 当需要 测试薄膜厚度时, 悬浮掩膜 5与基板 1共同压制住测试掩膜 2的边缘, 将所 述测试掩膜 2覆盖在所述基板的表面上, 提高测试掩膜 2与基板 1的紧密程 度。
进一步地, 可以将悬浮掩膜 5和测试掩膜 2结合为一体, 即所述悬浮掩 膜 5上设置有所述测试掩膜 2, 当需要测试薄膜 4的厚度时,所述悬浮掩膜 5 和基板 1共同作用, 使得所述测试掩膜 2覆盖在所述基板 1的表面上, 便于 测试掩膜 2的使用。
以图 5a~5c或图 6的内容为例, 其中, 图 5a~5c或图 6中各为一种将测 试掩膜 2设置在悬浮掩膜 5上的可能的实施方式。 这仅作为优选实施例来进 行说明, 对本发明的实施方式不进行任何限定。
如图 5a所示, 当所述测试装置处于非工作状态时,所述测试掩膜 2呈卷 曲状设置于所述悬浮掩膜 5底部的一侧, 当需要测试薄膜 4厚度时, 如图 5b 所示, 展开所述测试掩膜 2 , 使所述测试掩膜 2平铺在悬浮掩膜 5底面上, 如图 5c所示, 之后, 即可通过悬浮掩膜 5和基板 1之间的作用力, 将所述测 试掩膜 2覆盖在所述基板 1的表面上。 为了加强所述测试掩膜 2和悬浮掩膜 5之间的配合, 优选的, 可以在测 试掩膜 2上设置一个卡扣, 在悬浮掩膜 5底部设置有测试掩膜 2的对面一侧 设置有和该卡扣相配合的卡勾, 使得测试掩膜 2在平铺在悬浮掩膜 5的底面 之后, 通过卡扣和卡勾之间的配合, 加强所述测试掩膜 2和悬浮掩膜 5之间 的配合。
由于图 5a~5c所对应的装置实施例中的测试掩膜 2需要卷曲起来放置, 故而, 测试掩膜 2的材质必须具有较好的柔韧性、 延展性, 可考虑利用金属 或金属氧化物来制作测试掩膜 2 , 其中, 优选为绝缘的金属氧化物。
或者如图 6所示,直接将所述测试掩膜 2贴附在所述悬浮掩膜 5的底部, 在需要进行 莫厚度测试时, 将贴附有测试掩膜 2的悬浮掩膜 5放置在基板 上, 在确定所述测试掩膜 2覆盖在所述基板 1的表面上后, 对基板进行 1溅 射镀膜。
图 6所对应的实施例中的测试掩膜 2可采用任一种材质制作,例如金属、 金属氧化物、 陶瓷或玻璃等。
在本实施例的技术方案中, 提供了一种薄膜厚度的测试装置, 该测试装 置中的悬浮掩膜上设置有测试掩膜, 该测试装置使用方便, 适用范围广, 并 且使用该测试装置制得的待测的薄膜的边缘清晰, 台阶明显, 并且基板表面 上有多处可选择测试厚度的区域, 技术人员在使用探针测试时, 可任意选择 测试位置, 测试点数分布也可自行决定, 同时测试膜厚均一性范围较大, 测 试精度高; 并且该覆盖有薄膜的测试掩膜在经过清洁处理后, 可多次重复使 用, 与现有的掩膜法相比, 无需每次使用新的掩膜材料, 成本低且环保。
以上所述, 仅为本发明的具体实施方式, 但本发明的保护范围并不局限 于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易 想到变化或替换,这些变化或替换都应涵盖在本发明的保护范围之内。 因此, 本发明的保护范围应以所述权利要求的保护范围为准。
