Description
技术领域
本发明涉及布线基板和使用该布线基板的半导体器件以及布线基板的制造方法。
背景技术
作为使用了带式布线基板的封装体模块的一种,已知COF(Chip OnFilm:薄膜上芯片)。COF具有如下结构:在柔软的绝缘性带式布线基板之上安装半导体芯片,用树脂密封该半导体芯片,从而保护安装部分。作为主要的元件,带式布线基板包含绝缘性的薄膜基材和在该薄膜基材表面上形成的多条导体布线。薄膜基材一般使用聚酰亚胺薄膜,导体布线使用铜布线。根据需要,在导体布线上形成金属镀敷覆膜或阻焊剂(solder resist)膜。
COF的主要用途是用于驱动液晶面板等显示面板的驱动用驱动器的安装。例如在(日本)特开2004-327936号公报中,记载了COF所使用的布线基板的一例。图8表示在(日本)特开2004-327936号公报中记载的带式布线基板的一例。图8是表示带式布线基板中的包含了半导体安装区域的主要部分区域的平面图。在图8中,101表示内引线,102表示突起电极,103表示半导体安装区域。
在上述结构的布线基板中,在布线基板中安装半导体芯片时,加热和加压、或施加超声波振动而进行半导体芯片侧的电极(未图示)和突起电极102的接合。这种接合中使用的突起电极102通过电解电镀法等而形成,其高度通常容易产生偏差。它被认为是在电解电镀时,距电极形成部分的电流供给源的距离的偏差、或导体布线宽度或突起电极尺寸等的偏差所引起。突起电极102的高度有偏差时,产生在与半导体芯片接合时不能接合的突起电极102,并发生断路不良。

所述突起电极包括用于安装所述半导体芯片的第一突起电极、以及用于调整所述第一突起电极的高度的第二突起电极,
所述第二突起电极设置在至少一条所述导体布线的除所述半导体安装区域以外的区域。
本发明的半导体器件是包括上述本发明的布线基板和安装在该半导体安装区域上的半导体芯片的半导体器件。

具体实施方式
本发明的布线基板包括:绝缘性基材;设置在该绝缘性基材上,并且在安装有半导体芯片的半导体安装区域排列配置的多条导体布线;以及在这些各导体布线中所设置的突起电极。
绝缘性基材没有特别限定,但使用由聚酰亚胺等挠性材料构成的带式基材时,能够将本发明的布线基板作为可弯曲的布线基板来使用。再有,上述绝缘性基材的厚度例如为5~100μm左右。
导体布线例如由铜或铜合金等金属形成。导体布线的节距例如为10~100μm左右。而导体布线的高度及宽度例如分别为4~35μm及5~50μm左右。
各导体布线中所设置的突起电极包括:用于安装半导体芯片的第1突起电极;以及用于调整该第1突起电极的高度的第2突起电极。而且,该第2突起电极被设置在除了至少一条导体布线的半导体安装区域以外的区域中。
第1突起电极及第2突起电极例如由铜或金等金属构成,通过镀敷等手段而形成。第1突起电极的高度通常为1~20μm左右。第2突起电极设置在配置有在形成突起电极的步骤中容易相对变高的突起电极的导体布线上即可。例如,在通过电解电镀而形成突起电极的情况下,将其设置在电流容易集中的导体布线上即可。由此,电流被分散到第1突起电极和第2突起电极,所以设置了第2突起电极的导体布线上的第1突起电极的生长速度下降,能够使该第1突起电极的高度与其他导体布线上的第1突起电极的高度匹配。再有,第2突起电极的高度只要可减轻第1突起电极的高度的偏差就没有特别限定,例如为1~20μm左右。
本发明的半导体器件是包含上述本发明的布线基板和在该布线基板的半导体安装区域中安装的半导体芯片的半导体器件。根据本发明的半导体器件,由于使用上述本发明的布线基板,所以能够与用于接合半导体芯片的第1突起电极的高度匹配。由此,可以提高半导体芯片和第1突起电极之间的电连接可靠性。
本发明的布线基板的制造方法包括:(i)形成多条导体布线,使得该多条导体布线排列设置在绝缘性基材上的安装有半导体芯片的半导体安装区域;(ii)在所述绝缘性基材上的设置有所述导体布线的区域,形成光致抗蚀剂膜;(iii)通过在所述光致抗蚀剂膜中形成开口部分,使所述导体布线的一部分在所述开口部分中露出;(iV)对露出的所述导体布线的一部分施以金属镀敷,形成突起电极;以及(V)除去所述光致抗蚀剂;其特征在于,所述突起电极包括用于安装所述半导体芯片的第1突起电极和用于调整所述第1突起电极的高度的第2突起电极,在至少一条所述导体布线的除所述半导体安装区域以外的区域,设置所述第2突起电极。由此,能够与用于接合半导体芯片的第1突起电极的高度匹配,所以可以可靠地进行半导体芯片和第1突起电极之间的接合。
以下,一边参照附图一边说明本发明的实施方式。再有,在参照的附图中,有以相同的标号表示实质上具有同一功能的结构元件,省略重复的说明的情况。
(第1实施方式)
首先,参照图1A、图1B说明本发明的第1实施方式的布线基板。图1A是本发明的第1实施方式的布线基板的剖面图。而图1B是表示图1A的布线基板的包含半导体安装区域的主要区域的平面图。
如图1A、图1B所示,布线基板1包括:绝缘性基材10;设置在绝缘性基材10上,并且被排列配置在半导体安装区域11中的多条导体布线12;以及各导体布线12上所设置的突起电极13。
突起电极13包括:用于安装半导体芯片(未图示)的第1突起电极13a;以及用于调整第1突起电极13a的高度的第2突起电极13b。而且,如图1B所示,第2突起电极13b被设置在除了一部分导体布线12的半导体安装区域11以外的区域中。由此,例如在通过电解电镀而形成突起电极13时,电流被分散到第1突起电极13a和第2突起电极13b。因此,在设置了第2突起电极13b的导体布线12为电流容易集中的导体布线的情况下,该导体布线12上的第1突起电极13a的生长速度比以往下降。由此,能够使该第1突起电极13a的高度与其他导体布线12上的第1突起电极13a的高度匹配。此外,第2突起电极13b被设置在除了半导体安装区域11以外的区域中,所以在安装半导体芯片时,第2突起电极13b并不妨碍接合。
接着,参照图2A~图2E说明上述布线基板1的制造方法。图2A~图2E是表示布线基板1的优选的制造方法的不同步骤剖面图。
首先,如图2A所示,在绝缘性基材10上形成导体材料构成的导体布线12。作为导体布线12的形成方法,例如可以使用蚀刻法或半添加法等手段。作为导体布线12的材料,优选使用以铜、银、铝、锡、钯、镍、金等作为主要成分的材料。
接着,如图2B所示,在绝缘性基材10上的设置了导体布线12的区域中形成光致抗蚀剂膜15。作为光致抗蚀剂膜15的形成方法,一般有对片状的光致抗蚀剂膜15进行热压接的方法、涂敷液状的光致抗蚀剂而形成光致抗蚀剂膜15的方法等。光致抗蚀剂膜15的材料没有特别限定,可以是负型,也可以是正型。光致抗蚀剂膜15的厚度最好是比第1突起电极13a的厚度(高度)厚。例如,比第1突起电极13a的厚度厚2~10μm左右即可。
接着,如图2C所示,通过光刻法,在形成突起电极13的区域内形成开口部分15a。此时,形成开口部分15a,以使导体布线12的一部分露出。这时,对于与形成第1突起电极13a的区域相当的开口部分15a的图形,跨越相邻的导体布线12地连续开口也没有关系。此外,在与形成第2突起电极13b的区域相当的开口部分15a中,形成在半导体安装区域11(参照图1B)之外。考虑到通过光刻法形成开口部分15a时的光掩模的位置对准精度,最好是将与形成第2突起电极13b的区域相当的开口部分15a和与其相邻的导体布线12之间的间隔扩大。
接着,如图2D所示,通过电解电镀法,在开口部分15a(参照图2C)内形成突起电极13(第1及第2突起电极13a、13b)。在进行电解电镀的情况下,需要用于供给电的布线,但即使根据该布线的位置等也有可能对第1突起电极13a的高度产生影响,所以对于第2突起电极13b的尺寸(即,与形成第2突起电极13b的区域相当的开口部分15a的尺寸),需要考虑上述影响而进行调整。再有,在以往的布线基板中,突起电极的高度的标准偏差(σ)为1.4μm左右,而根据本发明,能够将标准偏差(σ)改善至0.8μm左右。
接着,例如使用碱类或有机类的药液来除去光致抗蚀剂膜15,获得图2E所示的布线基板1。再有,虽然未图示,但其后也可以形成用于保护规定的区域的阻焊剂膜。此外,为了保护导体布线12的最表面,也可以在导体布线12上形成镀金膜。
(第2实施方式)
下面,参照图3说明本发明的第2实施方式的布线基板。图3是表示第2实施方式的布线基板的包含了半导体安装区域的主要部分区域的平面图。
如图3所示,在布线基板2中存在导体布线12的节距稀疏的区域和密集的区域,在稀疏区域中配置的导体布线12a上设有第2突起电极13b。在用电解电镀形成突起电极13时,在节距稀疏的区域中,因镀液的流动差而比其他区域容易流入新的镀液。因此存在如下趋势:节距稀疏的区域的第1突起电极13a的高度变高。在这样的情况下,如上述那样,将第2导体布线13b设置在被配置在稀疏的区域中的导体布线12a上时,镀液被分散到第1突起电极13a和第2突起电极13b。由此,可以使节距稀疏的区域的第1突起电极13a的高度与其他区域的第1突起电极13a的高度匹配。
此外,在布线基板2的一部分导体布线12中,设置两个第2突起电极13b。这样,在本发明中,在因导体布线12的设计而对能够配置第2突起电极13b的区域的尺寸等有限制的情况下,也可以分割配置第2突起电极13b。再有,对于布线基板2的制造方法来说,在上述图2A~图2E所示的制造方法中,仅图2A的导体布线12的配置图形和图2C的开口部分15a的配置图形有所不同,能够通过同样的步骤来制造,所以省略其说明。
(第3实施方式)
下面,参照图4说明本发明的第3实施方式的布线基板。图4是表示第3实施方式的布线基板的包含半导体安装区域的主要部分区域的平面图。
如图4所示,在布线基板3中,在一部分导体布线12(导体布线12b)中设有两个第1突起电极13a。这样,在存在具有两个以上用于半导体连接的第1突起电极13a的导体布线12的情况下,该导体布线12上的第1突起电极13a有比其他导体布线12上的第1突起电极13a的高度低的趋势。为了补偿这种情况下的第1突起电极13a的高度,在布线基板3中,在各个导体布线12上设有相同数的突起电极13(第1及第2突起电极13a、13b)。由此,可以使第1突起电极13a的高度一致。再有,对于布线基板3的制造方法来说,在上述图2A~图2E所示的制造方法中,仅图2A的导体布线12的配置图形和图2C的开口部分15a的配置图形有所不同,能够通过同样的步骤来制造,所以省略其说明。
(第4实施方式)
下面,参照图5说明本发明的第4实施方式的布线基板。图5是表示第4实施方式的布线基板的包含半导体安装区域的主要部分区域的平面图。
如图5所示,在布线基板4中,第2突起电极13b被设置在区域40的外侧的区域中,区域40配置有包含半导体芯片的封装体(未图示)。通过具有上述结构,第2突起电极13b不会成为配置封装体时的妨碍。再有,对于布线基板4的制造方法来说,可以根据与上述图2A~图2E所示的制造方法同样的步骤来制造,所以省略其说明。
(第5实施方式)
下面,参照图6说明本发明的第5实施方式的布线基板。图6是表示第5实施方式的布线基板的包含半导体安装区域的主要部分区域的平面图。
如图6所示,在布线基板5中,第2突起电极13b被设置由阻焊剂膜(未图示)覆盖的区域50中。通过具有上述结构,在使用布线基板5形成了半导体器件时第2突起电极13b不露出,所以第2突起电极13b不会成为将上述半导体器件安装在玻璃基板等时的妨碍。再有,对于布线基板5的制造方法来说,可以根据与上述图2A~图2E所示的制造方法同样的步骤来制造,所以省略其说明。
(第6实施方式)
下面,参照图7说明本发明的第6实施方式的半导体器件。图7是第6实施方式的半导体器件的剖面图。再有,第6实施方式的半导体器件是使用了上述布线基板1(参照图1A、图1B)的半导体器件。
如图7所示,半导体器件6包括:布线基板1;以及在布线基板1的第1突起电极13a上所安装的半导体芯片60。半导体器件6使用本发明的一实施方式的布线基板1,所以能够与用于接合半导体芯片60的第1突起电极13a的高度匹配。由此,能够提高半导体芯片60和第1突起电极13a之间的电连接可靠性。再有,在图7中,61表示半导体芯片60的电极焊盘,62表示阻焊剂膜,63表示用于保护半导体芯片60的表面的表面保护膜,64表示用于保护的密封树脂。
如以上说明那样,根据本发明的布线基板及其制造方法,包含用于调整接合用突起电极(第1突起电极)的高度偏差的第2突起电极,所以能够可靠地进行半导体芯片和第1突起电极之间的接合。此外,根据本发明的半导体器件,使用上述本发明的布线基板,所以能够提高半导体芯片和第1突起电极之间的电连接可靠性。
