Description

带有凸块的布线电路板及其制造方法
发明领域
本发明涉及一种带有高度均一的凸块的布线电路板及其生产方法。
背景技术
在布线电路板与半导体元件或液晶显示元件的连接中,或者在多层布线板间进行层间连接中通常采用微凸块(比如说直径为50微米,高度为30微米)连接方式。
图3A到图3E举例说明了一种形成这种尺寸凸块的典型方法。
如图3A所示,首先,通过在聚酰亚胺膜31上粘贴铜箔32制备出双层柔性板33,然后在铜箔32上光刻出布线电路34图案(图3B)。
接下来,利用传统方式在布线电路34(图3C)上形成表面涂层35。举个例子说,可以在布线电路34上形成聚酰胺酸层图案,然后经光刻从而形成亚氨化的表面涂层35。另外一种方式是采用印刷方式在布线电路34上形成抗墨层。
然后,利用激光在对应于布线电路34(图3D)的聚酰亚胺膜31的相应位置进行照射形成凸块孔36,跟着按照需要在表面涂层35上涂覆一层保护膜(未示出),然后,在外露的布线电路34上自凸块孔36的底部向上形成金属凸块37(图3E)。
不过,在利用激光照射形成凸块孔36时,由于粘附在凸块孔36底部的粘附物数量不一致,布线电路34外露的面积也不一致,这就造成了金属凸块37高度的相当大程度的不一致性,这也导致了很难得到稳定的凸块连接。尤其是在利用超声连接技术将所有的半导体元件一次性地连接在布线电路上显得特别困难。同时,为了提高布线电路34和其上的金属凸块37之间的粘结强度,电镀预处理就显得特别重要。
发明内容
本发明意欲解决上述现有技术所遇到的问题,因此本发明的目的之一是提供一种带有凸块的布线电路板的生产方法,并且该电路板的凸块连接稳定可靠,不需要一些麻烦的工作如电镀预处理。
本发明人发现,用不着电镀预处理之类的烦人工作,而通过将金属箔局部蚀刻至深度相当于所述金属凸块高度就可以制作出高度均一的凸块,从而诞生了上述发明,其中,所述金属箔的厚度等于布线电路层的厚度和金属凸块高度之和,并且如果在该金属箔形成所述金属凸块的一面再形成由与该金属箔金属种类不一样的金属薄层,则该金属箔的形成所述金属凸块的一面和其上的绝缘层之间的附着力就会得到提高,该布线电路板的化学抵抗性也得到改善,金属箔也不会出现凸块所在面和其上的绝缘层的脱离,从而就可以获得稳定的凸块连接。
具体地说,本发明是一种带有凸块的布线电路板,在该布线电路板中,布线电路的一面形成表面涂层,另一面形成绝缘层,与布线电路导电相连的凸块自该绝缘层突出而形成,其中,所述布线电路和所述凸块由单独一片金属箔成一体地形成,而在所述绝缘层和所述布线电路形成有凸块的表面之间形成与所述金属箔金属种类不同的金属薄层。
此处,当该绝缘层为将聚酰亚胺前体层亚氨化而成的聚酰亚胺膜时,该金属薄层和该聚酰亚胺前体层之间的粘合力最好大于和金属箔之间的粘合力。此处金属箔和金属薄层结合的比较适宜的例子包括铜箔,与铜箔结合的金属薄层为镍,或锌,或锡,或者镍钴合金。在这种带有凸块的布线电路板中,最好是让所述表面涂层留有一个连接空处,以便可从该涂层面直接接触到所述布线电路。
本发明也是布线电路上形成有凸块的布线电路板的一种生产方法,该方法包括以下步骤:
(a)在金属箔形成有凸块的面上层叠保护膜并在金属箔上形成布线电路的面上形成布线电路生成蚀刻掩模,其中,所述金属箔的厚度等于布线电路层的厚度和在该布线电路上形成的金属凸块高度之和;
(b)从有布线电路生成蚀刻掩模的一面对该金属箔进行局部蚀刻,从而形成预定厚度的布线电路;
(c)去除布线电路生成蚀刻掩模,然后在该布线电路上形成表面涂层;
(d)去除金属箔形成有凸块的面上的保护膜,然后在此面上形成凸块生成蚀刻掩模;
(e)从有所述凸块生成蚀刻掩模的一面对该金属箔进行局部蚀刻,从而形成预定高度的凸块;
(f)去除所述凸块生成蚀刻掩模,然后形成金属种类与所述金属箔不同的金属薄层;
(g)在所述金属薄层上形成聚酰亚胺前体层并将凸块埋住;以及
(h)对所述聚酰亚胺前体层进行深蚀刻,并通过将其亚氨化而形成预定厚度的绝缘层;
利用这种方法,在形成凸块之前,先形成了布线电路。
另外,本发明为布线电路上形成有凸块的布线电路板的另外一种生产方法,该方法包括以下步骤:
(aa)在金属箔形成布线电路的面上层叠保护膜并在金属箔上形成凸块的面上形成凸块生成蚀刻掩模,其中,所述金属箔的厚度等于布线电路层的厚度和在该布线电路上形成的金属凸块高度之和;
(bb)从有所述凸块生成蚀刻掩模的一面对该金属箔进行局部蚀刻,从而形成预定高度的凸块;
(cc)去除所述凸块生成蚀刻掩模,然后形成金属种类与所述金属箔不同的金属薄层;
(dd)在所述金属薄层上形成聚酰亚胺前体层并将凸块埋住;
(ee)对所述聚酰亚胺前体层进行深蚀刻,并通过将其亚氨化而形成预定厚度的绝缘层;
(ff)去除金属箔形成布线电路的面上的保护膜,然后在此面上形成布线电路生成蚀刻掩模;
(gg)从有所述布线电路生成蚀刻掩模的一面对该金属箔进行局部蚀刻,从而形成预定厚度的布线电路;
(hh)去除所述布线电路生成蚀刻掩模,然后在该布线电路上形成表面涂层;
采用这种方法,凸块在布线电路之前形成。
附图说明
图1A到图1H为说明根据本发明的带有凸块的布线电路板的生产方法的步骤的简图;
图2A到2I为说明根据本发明的带有凸块的布线电路板的另一种生产方法的步骤的简图;
图3A到图3E为说明带有凸块的布线电路板的传统的生产方法的步骤的简图;
具体实施方式
以下将参考附图,对根据本发明的生产带有凸块的布线电路板的不同步骤予以详细说明。
首先,参考图1A到图1H,逐步地说明布线电路于凸块之前形成(步骤(a)到步骤(b))的布线电路上形成有凸块的布线电路板的生产方法。
步骤(a)
首先,在金属箔3形成凸块的面3a上层叠保护膜4并在金属箔3上形成布线电路的面3b上形成布线电路生成蚀刻掩模5,其中,所述金属箔3的厚度等于布线电路1的厚度t1(见图中的虚线)和将在该布线电路上形成的金属凸块2高度t2(见图中的虚线)之和(图1A)。
布线电路1的厚度t1和凸块2的高度t2根据布线电路板的用途进行最优选择。比如说,如果该布线电路板用作半导体元件的安装板,那么布线电路1的厚度t1可设为20微米,凸块2的高度t2可设为30微米,凸块2的直径可设为50微米。
布线电路板的导体层使用的任何材料都可用作金属箔3,但以使用铜箔为优选。
布线电路生成蚀刻掩模5可由抗墨物质在金属箔3的形成布线电路的面3b上经丝网印刷形成。另外一种方式是根据传统的方法采用曝光和显影让感光树脂层或干膜在该面上形成图案。
步骤(b)
然后,从有布线电路生成蚀刻掩模5的一面对该金属箔进行局部蚀刻,从而形成通常厚度t1的布线电路1(图1B)。
局部蚀刻的条件(如温度、蚀刻液成分)可根据金属箔3的材料类型、蚀刻厚度等予以适当地选择。
步骤(c)
采用普通方法去除布线电路生成蚀刻掩模5,然后在布线电路1上形成表面涂层6(图1C)。
表面涂层6可由涂层材料经丝网印刷形成。另外一种方式是根据传统的方法在该面上涂覆感光树脂层或干膜并采用曝光和显影让其形成图案。另外,由聚酰亚胺前体如聚酰胺酸组成的涂层可采用传统的方法涂覆、形成图案和亚氨化,从而形成表面涂层6。
在涂覆表面涂层6时,最好留出一个连接空处11,以便可从表面涂层6这一面直接接触到布线电路1。
步骤(d)
采用传统的方法去除涂覆在金属箔3将形成凸块的面3a上的保护膜,然后在凸块形成面3a上形成凸块生成蚀刻掩模7(图1D)。
凸块生成蚀刻掩模7可由抗墨物质在金属箔3的形成凸块的面3a上经丝网印刷形成。另外一种方式是根据传统的方法在该面上涂覆感光树脂层或干膜并采用曝光和显影让其形成图案。
步骤(e)
从有凸块生成蚀刻掩模7的一面对该金属箔3进行局部蚀刻,从而形成预定高度t2的凸块2(图1E)。
局部蚀刻的条件(如温度、蚀刻液成分)可根据金属箔3的材料类型、蚀刻厚度等予以适当地选择。
在局部蚀刻前,可在表面涂层6上覆盖一层保护膜(未示出)。
步骤(f)
采用传统的方法去除凸块生成蚀刻掩模7,然后形成金属种类与金属箔3不同的金属薄层10(图1F)。
金属薄层10最好由与聚酰亚胺前体层8(下面予以讨论)粘合力高的金属材料制成。这会在聚酰亚胺前体层8和金属箔3之间提供更好的粘合性,从而在接下来的化学处理(如在步骤(g)中对聚酰亚胺前体层8的深度蚀刻)中,金属箔3和聚酰亚胺前体层8或者金属箔3和通过对聚酰亚胺前体层8亚氨化而成的绝缘层9(见步骤(h))不会脱离。
当金属箔3为普通的铜箔时,金属薄层10的比较适宜的实例包括由镍,或锌,或锡,或者镍钴合金制成的金属薄膜。这些薄膜可通过无电电镀、电解电镀、或真空气相沉淀或其他诸如此类的方法制成。
如果金属薄层10太薄,绝缘层9和布线电路1之间的粘合力就不能得到很大的提高,但如果太厚,其所得效果又不与增加的厚度相对应,因此,比较合适的范围是0.01到4微米。尤其是,当金属薄层10是由锌或锡制成时,其优选厚度为0.1到0.5微米;当金属薄层10是由镍钴合金制成时,其优选厚度为0.1到4微米;当金属薄层10是由镍制成时,其优选厚度为0.01到1微米。
在去除凸块生成蚀刻掩模7时,如果表面涂层6上覆盖有保护膜时,此保护膜要同时去除。
步骤(g)
在金属薄层10上形成聚酰亚胺前体层8并埋住凸块(图1G)。
聚酰亚胺前体层8可由聚酰胺酸等经普通的生产工艺形成。亚氨化的条件可根据聚酰亚胺前体类型等来确定。
步骤(h)
聚酰亚胺前体层8经深度蚀刻及亚氨化形成预定厚度t3的绝缘层9。从而就生产出了如图1H所示的带有凸块的布线电路板。
接下来,参考图2A到图2I,逐步地说明布线电路上形成带有凸块的布线电路板的生产方法。其中,凸决于布线电路形成之前形成(步骤(aa)到步骤(hh))。图2A到图2I的结构单元与图1A到图1H中以相同数字标明的结构单元一致。
步骤(aa)
首先,在金属箔3形成布线电路的面3b上层叠保护膜4并在金属箔3上形成t凸块的面3a上形成凸块生成蚀刻掩模7,其中,所述金属箔3的厚度等于布线电路1的厚度t1(见图中的虚线)和将在该布线电路上形成的金属凸块2的高度t2(见图中的虚线)之和(图2A)。
步骤(bb)
从有凸块生成蚀刻掩模7的一面对该金属箔3进行局部蚀刻,从而形成预定高度t2的凸块2(图2B)。
步骤(cc)
采用传统的方法去除凸块生成蚀刻掩模7,然后形成金属种类与金属箔3不同的金属薄层10(图2C)。
步骤(dd)
在金属薄层10上形成聚酰亚胺前体层8并埋住凸块(图2D)。
步骤(ee)
聚酰亚胺前体层8经深度蚀刻及亚氨化形成预定厚度t3的绝缘层9(图2E)。
步骤(ff)
采用普通的方法去除涂覆在金属箔3将形成布线电路的面3b上的保护膜4,然后在布线电路形成面3b上形成布线电路生成蚀刻掩模5(图2F)。
步骤(gg)
从有布线电路生成蚀刻掩模5的一面对该金属箔3进行局部蚀刻,从而形成预定厚度t1的布线电路1(图2G)。
在此局部蚀刻之前,凸块2可被覆盖上一层保护膜(未示出)。
步骤(hh)
采用预定的方法将布线电路生成蚀刻掩模5去除(图2H),然后,在布线电路1上覆盖一层表面涂层6。从而就生产出了如图2I所示的带有凸块的布线电路板。此时最好留出一个连接空处11,以便可从表面涂层6的这一面直接接触到布线电路1。
在去除布线电路生成蚀刻掩模5时,如果凸块2上覆盖有保护膜,该保护膜要同时被去除。
如图1H和图2I所示,在利用上述根据本发明的生产方法生产出的带有凸块的布线电路板中,布线电路1的一面形成表面涂层6,另一面形成绝缘层9,与布线电路1导电相连的凸块2自该绝缘层9突出而形成,其中,所述布线电路1和所述凸块2由单独一片金属箔一体形成,而在所述绝缘层9和所述布线电路1形成有凸块2的一面之间形成有和所述金属箔金属种类不同的金属薄层10。当该绝缘层9为将聚酰亚胺前体层亚氨化而成的聚酰亚胺膜时,该金属薄层10最好由与聚酰亚胺前体层的粘合力大于与金属箔的粘合力的材料制成。比如说,当该金属箔为铜箔时,该金属薄层10可由镍,或锌,或锡,或者镍钴合金制成。这会在聚酰亚胺前体层和金属箔之间提供更好的粘合性,从而在化学处理(如对聚酰亚胺前体层的深度蚀刻)中,金属箔和聚酰亚胺前体层或者金属箔和通过对聚酰亚胺前体层亚氨化而成的绝缘层9不会脱离。
另外,由于此带有凸块的布线电路板的表面涂层6设有连接空处11,该连接空处11使得可从表面涂层6这面直接接触到布线电路1,这样从板的两面都可接触该板,这就提高了电子元件的安装密度。
本发明提供了一种带有凸块的布线电路板,在该布线电路板中,凸块强度稳定,凸块连接可靠,且不需要麻烦的操作如电镀预处理。尤其是,集成电路的凸块连接可通过超声技术一次性地稳定地生产出来。
