Description

镀膜设备 技术领域
本发明涉及到镀膜领域,尤其涉及到镀膜设备。
背景技术
镀膜技术是一种能够提升材料表面性能的有效手段,其通过采用在待镀膜工件表面形成膜层的方式来增强待镀膜工件表面的强度、防刮、耐磨性、散热性、防水性、耐腐蚀性或者是低摩擦性等性能。
从目前市场需求来看,镀膜技术在电子产品防护领域的应用受到越来越高的关注。待镀膜的电子产品各式各样,如PCB电路板、电子器件、手机、键盘、电脑等。其中每年手机的全球出货量达到15亿台以上,镀膜技术在手机PCB主板、PCB副板、充电口、TF卡口、耳机孔、屏幕等组件防护获得了广泛的应用。一般来说,手机不仅要求镀于其上的膜层具有增强手机表面的耐磨度和强度的功能,还对膜层的透光性有较高的要求。膜层的功能特性很大程度上是由镀膜设备、工艺技术等因素决定的。
目前镀膜技术主要采用的是真空气相沉积方法,其又可分为物理气相沉积法(PVD)和化学气相沉积法(CVD)。物理气相沉积法主要可分为真空蒸发镀膜、溅射镀膜、离子镀膜;化学气相沉积法可根据原料激活的方式分为热CVD、等离子体CVD、激光CVD、紫外线CVD等。
等离子增强化学气相沉积(PECVD)镀膜技术具有沉积温度低、沉积速率较高等诸多特点,是制备镀膜的另一常用技术手段。等离子增强化学气相沉积镀膜技术利用等离子体中的高能电子激活气体分子,促进自由基化和离子化,产生化学活性较强的高能粒子、原子或者分子态离子和电子等大量活性粒子,活性粒子化学反应生成反应产物。由于高能电子为源物质粒子提供了能量,因此不需要提供较多的外界热能就可以发生化学气相沉积,从而降低反应温度,这使得本来难以发生或者是反应速度很慢的化学反应成为可能。
在专利CN203411606U中揭露了一种镀膜设备,利用了等离子增强化学气相 沉积镀膜技术进行镀膜,其被设置有多个腔体,至少一个腔体用于镀膜前缓冲,至少一个腔体用于镀膜,至少一个腔体用于镀膜后冷却缓冲。显然,这样的镀膜设备结构较为复杂,比如说独立的腔体之间需要被设置有控制阀门,还需要额外设置在多个腔体之间传送待镀膜工件的装置。在生产过程中一旦产生故障,维修的难度和成本也可能由于多个腔体的存在而增加。
因此,如何提供一种结构简单、适于大批量制备膜层的镀膜设备,是目前急需解决的问题。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例,本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
本领域技术人员应理解的是,在本发明的揭露中,术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系,其仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此上述术语不能理解为对本发明的限制。
可以理解的是,术语“一”应理解为“至少一”或“一个或多个”,即在一个实施例中,一个元件的数量可以为一个,而在另外的实施例中,该元件的数量可以为多个,术语“一”不能理解为对数量的限制。
本发明提供了一镀膜设备,其中所述镀膜设备可以用于制备各种类型的膜层,比如类金刚石薄膜(DLC膜),有机膜。所述镀膜设备通过利用等离子体增强化学气相沉积(PECVD)技术在一待镀膜工件表面化学沉积形成膜层。具体地说,所述待镀膜工件被放置在所述镀膜设备的一反应腔体中进行等离子增强化学气相沉积从而在所述待镀膜工件的表面形成所述膜层。
等离子体增强化学气相沉积(PECVD)工艺相对于现有的其他沉积工艺具有很多优点:(1)干式沉膜不需要使用有机溶剂;(2)等离子体对基体表面的刻蚀作用,使所沉积上的薄膜与基体粘结性好;(3)可以对不规则基体表面均匀沉积镀膜,气相渗透性极强;(4)涂层可设计性好,相比于液相法微米级控制精度, 化学气相法可在纳米级尺度进行涂层厚度的控制;(5)涂层结构设计容易,化学气相法使用等离子体激活,对不同材料的复合涂层不需要设计特定的引发剂进行引发,通过输入能量的调控即可将多种原材料复合在一起;(6)致密性好,化学气相沉积法在等离子体引发过程中往往会对多个活性位点进行激活,类似于溶液反应中一个分子上有多个官能团,分子链之间通过多个官能团形成交联结构;(7)作为一种镀膜处理技术手段,其普适性极好,镀膜的对象、镀膜使用的原材料选择的范围都很广。

相邻的所述支撑件411界定的空间通过所述出气口201可以被连通,从而有利于位于各层的所述支撑件411的所述待镀膜工件所处环境中气体的均匀性,进而有利于位于各层的所述支撑件411的所述待镀膜工件的镀膜的均匀性。
更加具体地说,在本实施例中,所述多层支架41包括多个所述支撑件411和至少二连接件412,其中所述支撑件411被支撑于所述连接件412,以被保持于所述反应腔100。在本实施例中,所述连接件412被实施为一立柱,其中所述立柱可以是中空的,也可以是实心的。

不同气体之间的流量比决定了获得DLC膜层的原子比,影响了膜层质量,所述放电装置50的所述电源的大小决定了电离过程的温升、离化率和沉积速率等相关参数,镀膜时间过短将使得膜层较薄,硬度表现较差,镀膜时间过长将使得膜层较厚,影响到透明性。
在本发明的另一些实施例,利用所述镀膜设备1,可以获得有机膜层,比如说进行以下步骤Ⅰ或步骤Ⅱ至少一次,在基材表面制备调制结构的有机硅纳米涂层:步骤I:通入单体A蒸汽到反应腔体10内,至真空度为30~300毫托,开启等离子体放电,进行化学气相沉积,停止通入单体A蒸汽,通入单体B蒸汽,继续等离子体放电,进行化学气相沉积,停止通入单体B蒸汽;步骤Ⅱ:通入单体B蒸汽到反应腔体10内,至真空度为30~300毫托,开启等离子体放电,进行化学气相沉积,停止通入单体B蒸汽,通入单体A蒸汽,继续等离子体放电,进行化学气相沉积,停止通入单体A蒸汽。

进一步地,所述放电装置50的电源可以是所述脉冲电源52和/或所述射频电源51。所述脉冲电源52可以单独使用,所述射频电源51也可以单独使用,或者是所述脉冲电源52和其他装置配合使用,比如说微波或者是射频,或者是所述射频电源51和其他装置配合使用,比如说微波或者是脉冲。
在本实施例中,所述放电装置50中的所述射频电源51和所述脉冲电源52被共同配合使用,比如说先以所述射频电源51作为电感耦合离子源的电源供应,然后通过线圈的电感耦合作用,产生交变磁场,从而实现气体电力。所述射频电源51的功率可以为12MHz~14MHz,比如说13.56MHz。
所述脉冲电源52可以被加载在作为阴极的所述电极53,通过辉光放电效应电离气体,同时对于电离产生后的正离子具有定向牵引加速作用。在膜层沉积过程中有轰击作用,从而可以获得致密的高硬度镀膜。
所述射频电源51和所述脉冲电源52的同时应用,使得在反应过程中可以获得高离化率的等离子体基础上,增加了等离子体达到基体表面时的能量,从而有利于获得致密透明的膜层。
举例说明,根据本发明的至少一实施例,利用所述镀膜设备1,可以获得DLC膜层,首先对于待镀膜工件表面清洁预处理。将玻璃、金属、塑料等材质制作的待镀膜工件用酒精或者丙酮等溶剂进行表面清洗,再用无尘布擦拭或者先经过超声浸泡后擦干;将待镀膜工件放置于真空反应腔中,抽真空至10Pa以下,更佳地应该抽真空至0.1Pa以下,通入高纯氦气或者氩气作为等离子体气源,打开高 压脉冲电源52,辉光放电产生等离子体,对样品表面进行刻蚀与活化;然后沉积DLC薄膜。利用射频与高压脉冲共辅助等离子体化学气相沉积的方法制备掺杂类金刚石碳膜:通入DLC薄膜反应气体源、掺杂元素的反应原料、氢气,打开所述射频电源51和高压脉冲电源52进行等离子体化学气相沉积,经过一段时间后,沉积薄膜过程结束,通入空气或者惰性气体使真空腔回复至常压,取出样品。
值得注意的是,所述脉冲电源52的负偏压值的大小可以关系到气体离化情况和达到产品表面时的迁移能力。高电压意味着更高的能量,可以获得高硬度涂层。但是过高的离子能量,会对于待镀膜工件产生很强的轰击效应,在微观尺度上会在待镀膜工件的表面产生轰击坑,同时高能量轰击会加快温度提升,可能导致所述待镀膜工件的升高。
进一步地,在本实施例中,所述脉冲电源52的脉冲频率可以是20~300KHz,可以减少绝缘的待镀膜工件表面的电荷持续积累,从而抑制大电弧现象和增加涂层沉积厚度极限。
