传统制程中,电极和周边引线需分开进行图案化,而图案化这一制程动作本身又包含了复杂的工序步骤,如烘干、曝光、显影、蚀刻、剥膜,如此使得制程工艺复杂,导致制程效率无法提升。
发明内容
鉴于上述,本发明在于提供一种触控感应层及其制作方法,乃利用同步图案化的制程步骤形成电极与周边引线,从而可简化生产流程以提升制程效率。
  本发明提供一种触控感应层的制造方法,其特征在于,包含以下步骤:(a) 形成一第一导电层于一基板上;(b) 形成一第二导电层于该第一导电层上;(c) 同步图案化该第一导电层和该第二导电层,以分别形成一图案化复合导电层以及至少一周边引线;以及(d) 移除该图案化复合导电层中的该第二导电层以形成至少一电极,其中该些周边引线电性连接至对应的该些电极。

具体实施方式
以下将详述本案的各实施例,并配合图示作为例示。除了这些详细描述之外,本发明还可以广泛地施行在其他的实施例中,任何所述实施例的轻易替代、修改、等效变化都包含在本案的范围内,并以之后的专利范围为准。在说明书的描述中,为了使读者对本发明有较完整的了解,提供了许多特定细节;然而,本发明可能在省略部分或全部这些特定细节的前提下,仍可实施。此外,众所周知的步骤或元件并未描述于细节中,以避免造成本发明不必要之限制。图示中相同或类似之组件将以相同或类似符号来表示。特别注意的是,图示仅为示意之用,并非代表元件实际的尺寸或数量,除非有特别说明。
图2A与图2B为本发明一实施例中的触控感应层结构示意图,其中图2B为图2A沿A-A'方向的剖面图。本实施例中,触控感应层10包含位于可视区VA的电极1与位于非可视区VS的周边引线2,其中周边引线2电性连接电极1。电极1由第一导电层21制成。周边引线2由第一导电层21与第二导电层22制成,故周边引线2为一种双层导电结构。
本发明一实施例中,电极1与周边引线2均由第一导电层21制成,故电极1与周边引线2的电性连接是通过第一导电层21本身,故电极1与周边引线2之间无需通过其他重叠的搭接方式进行导通,换言之,电极1与周边引线的连接处无重叠,从而避免了因重叠处存在高度差而引起的断路等问题。
图3为制作上述触控感应层的方法流程图。请参照图3,触控感应层的制作方法包括以下步骤:(a) 形成一第一导电层于一基板上;(b) 形成一第二导电层于该第一导电层上;(c) 同步图案化该第一导电层和该第二导电层,以分别形成一图案化复合导电层以及至少一周边引线;以及(d) 移除该图案化复合导电层中的该第二导电层以形成至少一电极,其中该些周边引线电性连接至对应的该些电极。
请合并参考图4A与图4B,其中图4A是绘示上述步骤(a)的结构示意图,图4B为图4A沿水平方向的剖面图。步骤(a),形成第一导电层21于基板20上,如图4A至图4B所示,其中形成的方式可为沉积、蒸镀、印刷、涂布、溅镀等。
请合并参考图5A与图5B,其中图5A是绘示上述步骤(b)的结构示意图,图5B为图5A沿水平方向的剖面图。步骤(b), 形成第二导电层22于第一导电层21上,如图5A及图5B所示,其中形成的方式可为沉积、蒸镀、印刷、涂布、溅镀等。
请合并参考图6A与图6B,其中图6A是绘示上述步骤(c)的结构示意图,图6B为图6A沿B-B'方向的剖面图。步骤(c),同步图案化第一导电层21和第二导电层22,以分别形成图案化复合导电层23以及周边引线2,如图6A及图6B所示。其中,周边引线2分别电性连接于图案化复合导电层23,且图案化复合导电层23大致上位于基板20的可视区域VA,周边引线2大致上位于基板20的周边区域SA。
于本实施例,较佳地,是采用一雷射蚀刻方式同时图案化第一导电层21和第二导电层22。依照所要形成的图案,利用雷射划线蚀刻机,控制合适的雷射蚀刻参数,同时将第二导电层22与其下方的第一导电层21所需蚀刻的部份蚀刻完全,且避免蚀刻到第一导电层21下的基板20,例如塑胶基板。在一实施例中,雷射蚀刻选用波长1064 nm的雷射光束,并搭配下列参数:功率3W,雷射频率70K,划线速度1000mm/s,按照上述参数,可蚀刻出线宽和线距为30±5μm的周边引线2。在另一实施例中,雷射蚀刻选用波长355 nm的雷射光束,并搭配下列参数:功率0.7W,雷射频率100K,划线速度1000mm/s,按照上述参数,可蚀刻出线宽和线距为15±5μm的周边引线2。故通过调整镭射蚀刻时所使用的波长和其他相关参数,可得到线宽为10μm至35μm的周边引线。由于雷射蚀刻精度上较容易控制,使用本实施例的制作方法,周边引线2的线距可达到大约10μm至35μm。
在本发明另一实施例中,是采用微影蚀刻的方式同步图案化第一导电层21和第二导电层22。在本实施例中,在上述步骤(b)完成后,先形成一光阻层于第二导电层22上,再经过前烘干、曝光、显影、后烘干、蚀刻、剥膜等工序形成图案化复合导电层23以及周边引线2。
请合并参考图7A与图7B,其中图7A是绘示上述步骤(d)的结构示意图,图7B为图7A沿C-C'方向的剖面图。步骤(d) 移除图案化复合导电层23中的第二导电层22以形成电极1,其中该些周边引线2电性连接至对应的该些电极1,如图7A及图7B所示。例如,利用干蚀刻或湿蚀刻移除第二导电层22。于本实施例,可视区域VA中图案化复合导电层23中的第二导电层22,可通过一蚀刻液蚀刻移除,其中由于第一导电层21与第二导电层22具有相异的蚀刻属性,因此可选用适当的蚀刻液,使该蚀刻液仅会对第二导电层22有蚀刻作用,却不会对第一导电层21有蚀刻作用。因此,蚀刻液的选用需根据第二导电层22的材料来确定,例如,如果第二导电层22的材质为钼-铝-钼(Mo-Al-Mo)合金,则使用醋酸-硝酸-磷酸溶液作为蚀刻液;如果第二导电层22的材质为铜,则使用氯化铁溶液作为蚀刻液。
图8为制作上述触控感应层的另一方法流程图。本实施例与上述方法实施例的区别之处在于:于步骤(c)与步骤(d)之间更包含一步骤(e),即形成一保护层24在周边引线2上,并使图案化复合导电层23裸露。请合并参考图9A与图9B,其中图9A是绘示上述步骤(e)的结构示意图,图9B为图9A沿D-D'方向的剖面图。在一实施例中,保护层24系采用丝网印刷方式形成的一防蚀刻油墨层,以遮蔽并保护周边区域SA的周边引线2,同时暴露出位于可视区域VA的图案化复合导电层23;接着,以加热或紫外光照射方式固化处理防蚀刻油墨层。于另一实施例中,以丝网印刷方法,在周边区域SA印刷可剥离胶层24以保护周边引线2,同时暴露出位于可视区域VA的图案化复合导电层23;接着,通过紫外光或加热方式使可剥离胶层固化。形成保护层24后,再进行步骤(d)的移除第二导电层22动作,以防止周边引线2在步骤(d)的过程中被腐蚀。
在本发明一实施例中,于步骤(d)之后更包含一步骤(f),即移除上述保护层24。于本实施例,使用一剥膜液移除保护层24,例如氢氧化钾(KOH)溶液,将防蚀刻油墨24或可剥离胶24剥离。
在本实施例中,其余步骤及使用材料皆与上述方法实施例类似,在此不再赘述。
藉由上述方法,即可在基板20上形成触控感应层10。
此外,较佳地,所述触控感应层10是一种用于电容式触控面板的触控感应结构,其形态不拘于图2A所示的单层单轴结构,也可以是一单层双轴结构、一双层双轴结构等。
需要说明的是,在前述各实施例中,基板20可以是一透明无机基板,例如一玻璃基板;或一透明有机基板,例如一塑胶基板,其材质例如聚乙烯对苯二甲酸酯(Polyethylene terephthalate, PET)、聚碳酸酯(Poly Carbonate, PC)、聚乙烯(Polyethylene, PE)或聚甲基丙烯酸甲酯(Polymethylmethacrylate,PMMA)等。第一导电层21为透明导电材料,其材料可以选自下列群组的其中之一或其组合:氧化铟锡(ITO)、氧化锑锡(ATO)、氧化锌(ZnO)、二氧化锌(ZnO2)、二氧化锡(SnO2)、三氧化二铟(In2O3)。第二导电材料22为金属材料,其材料包含任何可以导电的金属或合金,例如铜、铜合金、钼-铝-钼合金、银、银合金等等。
本发明实施例提供的触控感应层及其制作方法,乃利用同步图案化的制程步骤形成电极与周边引线,从而可简化生产流程以提升制程效率,此外若在图案化步骤中使用镭射蚀刻的方式,所制作出的周边引线更加精细。
以上所述仅为本发明之较佳实施例而已,并非用以限定本发明之申请专利范围;凡其他未脱离发明所揭示之精神下所完成之等效改变或修饰,均应包含在下述之申请专利范围内。
