Description

半导体器件
技术领域
本发明涉及具有CSP(Chip Size Package,芯片尺寸包装)结构的半导体器件,其制造方法,和具有该半导体器件的电子器件。
背景技术
近来已知具有芯片和包装尺寸彼此几乎相等的CSP结构的半导体器件,并且其用于增加电路板上的安装密度。图16示出了这种结构的一个例子。图16是表示一个半导体器件20的截面图。半导体器件20具有通过将一个晶片切割成各芯片获得的所说的晶片级CSP结构,该晶片具有包括下列步骤的包装处理:保护膜形成步骤,导电层形成步骤,柱形成步骤,和树脂封装步骤。
从一个晶片形成半导体器件20。支撑一个电路元件或多个元件的半导体基衬1的表面(电路表面侧)具有从由铝电极等制成的多个连接盘2。在包括连接盘2的上表面的半导体基衬1的电路侧上形成由二氧化硅、氮化硅等制成的钝化膜(绝缘膜)3,以暴露每个连接盘2的中央。
在钝化膜3的上表面形成具有开口以暴露每个连接盘2的中央的保护膜4。保护膜4例如通过下列方式形成,在晶片1的整个电路表面侧施加聚酰亚胺基树脂,将树脂固化,用蚀刻溶液执行抗蚀图案和保护膜图案,并且去除抗蚀剂。
在以上述方式形成的保护膜4上形成电连接到连接盘2的导电层5。在导电层5上的预定部分形成由铝电极制成的柱6。在每个柱6的顶端面6a上已经自然形成的氧化膜被去除,并且进行涂敷金属处理诸如焊接印刷。柱6用于连接电路板上的一个端子(未示出)。柱6的高度至少是50微米,并且典型地约为100到150微米。柱6形成为直的形状,以吸收半导体基衬1和电路板之间热膨胀系数之差产生的压力。
在柱6之间的半导体基衬1的整个表面侧上形成由树脂诸如聚酰亚胺基树脂或环氧树脂制成的封装膜7。
由无源元件形成的滤波电路和天线单元需要通过使用具有上述晶片级CSP结构的半导体器件20,实现诸如蓝牙模块或GPS接收模块的RF射频电路。这些无源元件不能常规地安装在芯片内,并且作为分立元件安置在芯片外。这使得难以微型化模块。
在这种RF电路模块中,元件之间的布线长度影响频率特性,并且该长度难以进一步缩短。因此,频率特性难以进一步改善。

本发明提供一种半导体器件制造方法,包括:制备半导体基衬,在该基衬的上表面形成电路元件形成区和多个连接盘;形成连接到所述多个连接盘中的至少一个第一连接盘的至少一个第一导电层;形成电连接到所述多个连接盘中的至少一个第二连接盘的第一柱状电极;至少围绕着所述第一柱状电极在所述半导体基衬上和所述第一导电层上形成封装膜;和在所述封装膜上形成至少一个第二导电层以面对所述第一导电层。

具体实施方式
下面将参照附图详细描述按照优选实施例的半导体器件及其制造方法。
<第一实施例>
图1是表示按照本发明第一实施例的半导体器件200的结构的截面图。图2和3是表示半导体器件200的表面(电路表面侧,一个焊球B从此处被移去)的不同示例的平面图。在图1到3中,与图16所示的现有技术相同的标号表示相同的部件,并且将适当地略去对其描述。
类似于图16所示的传统半导体器件20,图1、2和3所示的半导体器件200包括:在支撑一个电路元件或在电路元件形成区DA内以集成方式形成的元件的半导体基衬1上形成的多个连接盘2。由二氧化硅、氮化硅等制成、并形成在半导体基衬1的表面上,以暴露每个连接盘2的中央的钝化膜3,和在钝化膜3的上表面上形成的保护膜4。
与传统的半导体器件20类似,按照第一实施例的半导体器件200包括:形成于保护膜4上并且电连接到连接盘2(第一导电层5)的导电层5;形成于导电层5上的柱6。半导体器件200进一步包括:在连接盘2中,连接到地电位的至少一个接地盘2A(第二连接盘),和连接到预定电路并且接收预定电源的至少一个馈电盘2B(第三连接盘)。半导体器件200进一步包括一个地平面GP,其从至少一个导电层5-1(第一导电层)和至少一个上导电层8(第二导电层)形成,所述至少一个导电层5-1连接到接地盘2A并且在保护膜4上延伸,所述至少一个上导电层8形成于封装膜7上并且这样安排使得通过膜7的部分面对导电层5-1。半导体器件200还具有:柱6A(第一柱状电极),其通过导电层5-1电连接到接地盘2A,并且连接到上导电层8;柱6B(第二柱状电极),其通过导电层5-1电连接到馈电盘2B,并且连接到上导电层8。
如图2所示,电连接到接地盘2A的导电层5-1和电连接到接地盘2A和馈电盘2B的上导电层8设置在它们通过封装膜7互相面对的位置。导电层5-1用作处于地电位的地平面GP,并且相对的上导电层8用作馈电电极,于是形成倒F形的天线。盘被电连接到在半导体基衬上的电路元件形成区DA中形成的电路元件。
在第一实施例中,倒F形天线形成为天线单元。然而,本发明不限于此,而是可以形成诸如倒L形天线、接插(patch)天线和微波传输带天线。
在图1和2中的半导体基衬1上形成一个天线单元,但是本发明不限于此。例如,在一个芯片上可以排列多个天线,一构造一个相控阵列天线,并且可以获得希望的方向特性。或者,可以形成多个天线单元,并且可以改变它们的方向,以减少天线的方向性。图3示出了一个器件的例子,其中,从第一天线单元和第二天线单元形成两个天线单元,并且这些天线单元的方向相差90度,所述第一天线单元由用作地平面GP的导电层5-1和相面对的上导电层8-1构成,所述第二天线单元由用作地平面GP的导电层5-2和相面对的上导电层8-2构成。
图4到9是用于解释按照本发明第一实施例的半导体器件200的制造步骤的截面图。将参照图4到9解释这些制造步骤。
在按照第一实施例的制造步骤中,如图4所示,由二氧化硅、氮化硅等制成的钝化膜3形成于由铝电极等制造的多个连接盘2的上表面上,并且形成于晶片(半导体基衬)1的表面上。基衬支撑在电路元件形成区形成的电路元件,并且具有多个芯片形成区。钝化膜3如此形成以便暴露每个连接盘2的中央。多个盘包括至少一个接地盘2A和至少一个馈电盘2B。然后,在钝化膜3的上表面上形成具有开口以便暴露连接盘2的中央的保护膜4。保护膜4例如通过下列方式形成,在晶片1上的钝化膜3和盘2的整个上表面施加聚酰亚胺基树脂,将树脂固化,用蚀刻溶液执行抗蚀图案和保护膜图案,并且移去抗蚀剂。
保护膜4的形成能够采用通过旋涂施加聚酰亚胺基树脂的方法,使用橡胶滚轴的印刷方法或喷墨涂层方法。保护膜材料不限于聚酰亚胺基树脂,并且可以是环氧基树脂,PBO(聚苯并噁唑-基树脂)等。
如图5所示,通过在保护膜4和钝化膜3中形成的开口而暴露的连接盘2和馈电盘2B的部分上形成导电层5。在接地盘2A上形成对应于地平面GP的导电层5-1。
导电层5和5-1形成如下。由铜(Cu)、钛(Ti)等制造的UBM(Under Bump Metal)层(未示出)通过喷射等沉积在保护膜4的整个表面上。光致抗蚀剂施加到UBM层、固化、然后通过光刻蚀法相应于具有预定形状的开口制模。由抗蚀剂形成的开口通过使用UBM层作为电流路径,进行电镀。
导电层5和5-1可以通过无电电镀形成。用于这些导电层的材料的例子是呈现好的导电特性的铜、铝和金和它们的合金。
如图6所示,在导电层5和5-1上的预定位置处,从柱状电极形成柱6,6A和6B。
通过例如施加光致抗蚀剂约100到150微米、将光致抗蚀剂固化、形成暴露导电层5和5-1的预定部分的开口和通过使用UBM层作为电流路径执行用于开口内部的电镀形成所述柱。也可以通过无电电镀或间柱碰撞方法形成每个柱。
柱材料的例子是呈现好的导电特性的铜、焊锡、金和镍。当焊锡用作柱形成材料时,通过后面的回流处理还能形成一个球形电极。当使用焊锡形成柱6时,除了上述方法,还能采用印刷方法。在形成柱6之后,蚀刻掉UBM层的不需要部分。
如图7所示,例如通过用诸如聚酰亚胺或环氧树脂浇铸晶片1的整个表面侧,以覆盖柱、保护膜和导电层,形成封装膜7。封装膜7最好由基本包含与上述保护膜4相同的主要成分的树脂制成,以便确保对付环境变化的可靠性。除了上述浇铸方法,形成封装膜7的方法还可以是印刷方法、浸渍方法、旋涂或压铸。
在形成封装膜7之后,切割并打磨封装膜7的上表面,以暴露柱6、6A和6B的末端面6a,并且去除部件的上表面上的氧化膜,如图8所示。
诸如铜箔的金属箔通过在膜7上进行焊锡印刷等被碾压,并且被选择性地蚀刻,以此形成电连接到相应于接地盘2A的柱6A和相应于馈电盘2B的柱6B的上导电层8。或者,用作上导电层8的导电板可以用导电粘合剂固定到相应于接地盘2A和馈电盘2B的柱6A和6B。
如果需要,在没有用上导电层8覆盖的柱6上放置焊球B,于是形成终端部分,如图9所示。
沿着预定的切割线将晶片1切割成芯片形成区。结果,形成具有图1所示结构的半导体器件200。
即,制造具有图1所示结构的半导体器件200,即由从导电层5-1和上导电层8形成的地平面GP构成的倒F形天线,所述上导电层8形成于对应接地盘2A和馈电盘2B的柱6A和6B之上以便电连接到柱6A和6B。
图10和11示出当具有该结构的半导体器件200安装在支撑预定布线图的布线板时适合的安装结构。
在图10所示的结构中,支撑多个布线图的布线板30设置在电子设备壳体40内。半导体器件200通过经形成在柱6上的焊球B连接到形成在布线板30上的预定布线图31,被安装在布线板30上。起半导体器件200的天线作用的上导电层8面向布线板30。
如果在面向布线板30的上导电层8的区域32中存在布线图,通过上导电层8辐射的无线波的辐射效率减少或辐射图被干扰,降低了天线性能。为了防止这些,在面对布线板30的上导电层8的区域32中不形成布线图。相应地,能够抑制在天线性能方面的下降。
在图11所示的结构中,面对布线板30的上导电层8的区域32是一个开口。在该情况下,几乎没有部件干扰上导电层8辐射的无线波。能够最小化无线波的辐射效率和天线性能的下降,并且能够获得好的性能。
如上所述,通过形成导电层5-1作为地平面GP,并且在电连接到接地盘2A和馈电盘2B的柱6A和6B上形成上导电层8,第一实施例构成倒F形天线。天线可以安装在芯片内,并且能够微型化具有使用该芯片构成的天线的模块。
由于天线安装在芯片内部,从芯片上的电路到天线的布线长度与天线设置在芯片外的结构相比能够大大缩短。能够最小化构成天线的电极的馈线损耗。这有益于传输信道特性的改善并且提供高性能的天线。
在上述实施例中,在地平面GP和上导电层8之间插入封装膜7。作为替换,如图12所示,可以在地平面GP和上导电层8之间插入高介电部件11。在该情况下,在形成柱6、6A和6B之后,介电部件11用粘合剂等固定到地平面GP(导电层5-1)。然后,通过上述封装步骤设置上导电层8。
通过在地平面GP和上导电层8之间插入由钡钛等制成的高介电部件,能够调节天线单元的导电长度。换言之,不用改变上导电层8的图案尺寸就能够改变天线单元的谐振频率。当天线单元的谐振频率保持恒定时,通过安装高介电部件,能够减少地平面GP和上导电层8的区域。
<第二实施例>
图13A是按照本发明第二实施例的半导体器件200的截面图。在图13A中,与第一实施例相同的参考标号表示相同的部件,并且适当地略去对其的描述。
按照第二实施例的半导体器件200包括:连接到预定连接盘2C(第二连接盘)的导电层5-2(第一导电层),和形成在封装膜7上的上导电层12(第二导电层)。如图13A所示,导电层5-2和上导电层12形成于它们经封装膜7的部分互相面对的位置。通过在上导电层12上进行涂覆金属处理诸如焊锡印刷,形成焊接层B’。
图13B是表示图13A所示的半导体器件200安装在布线板30上的状态的截面图。在该情况下,上导电层12通过焊接层B’连接到形成在布线板30上的盘33。上导电层12、封装膜7和导电层5-2形成容性元件Cp。
通过导电层5电连接到导电盘2的柱6经焊球B连接到布线板30的布线图31。
在布线板30上的盘33和芯片内的导电层5-2之间能够形成容性元件Cp,能够构成如图13C所示的等效电路。在图13C中,参考标号200a表示预先形成在半导体器件200的半导体基衬1上的电路部件,如图13A所示。容性元件Cp能够连接到电路部件200a。
按照第二实施例,能够集成容性元件和芯片。当使用该芯片构成具有容性元件的模块时,该模块与容性元件安排在芯片外的传统结构相比能够微型化。
在上述实施例中,在上导电层12的部件和导电层5-2之间插入封装膜7,以形成容性元件。作为替换,如图14所示,可以在上导电层12和导电层5-2之间插入介电层13,以形成容性元件Cp。在该结构中,由插在上导电层12和导电层5-2之间的介电层13的相对介电常数、厚度和面积确定容性元件的电容。使用高相对介电常数的电介质能够增加电容值,而不用改变上导电层12和导电层5-2的面积。当电容值保持恒定时,可以减少每个导电层的面积。形成介电层13的高相对介电常数电介质材料是诸如钡钛或钽钛。
图15A到15C示出了第二实施例的修改。图15A是示出修改的半导体器件200及半导体器件200安装在布线板30上的状态的截面图。图15B是示出封装膜7被略去的半导体器件200的表面的平面图。
如图15A所示,修改包括电连接到导电层5-3和10(第一导电层)的连接盘2D(第二连接盘)。此外,修改包括形成在通过介电层13它们面对导电层5-3和10的位置处的上导电层12-1和12-2(第二导电层)。
在导电层10上形成柱状电极6,并且在柱状电极6上形成焊球B。柱状电极6通过焊球B电连接到形成在布线板30上的盘36。通过进行涂覆金属处理诸如焊锡印刷在上导电层12-1和12-2上形成焊接层B’。上导电层12-1和12-2通过焊接层B’连接到形成在布线板30上的盘35。
用这种安排,在上导电层12-1和导电层5-3之间、及上导电层12-2和导电层10之间分别形成在结构上与容性元件Cp相等的两个容性元件C1和C2。
如图15B所示,导电层10具有方形线圈形状的图案以形成感性元件L。
通过组合容性元件C1和C2及感性元件L能够构成各种无源电路。例如,能够形成图15C所示的π低通滤波器,并且被连接到在半导体基衬1上形成的电路部件200a。从无源元件形成的滤波电路能够安装在芯片内,并且能够微型化带有使用该芯片构成的滤波电路的模块。
在该修改中,通过组合两个容性元件和一个感性元件实现滤波电路。本发明不限于此,通过组合多个容性元件、感性元件和导电层可用构成各种无源电路。
此外,本发明不限于容性元件和感性元件,在半导体基衬1上形成的导电层可以形成各种薄膜电路元件,诸如电阻、薄膜变压器、薄膜SAW(Surface Acoustic Wave,声表面波滤波器)、微带线和MMIC(Microwave Monolithic Integrated Circuit,微波单片集成电路)。或者,这些元件可用组合构成各种无源电路。
在该情况下,各种无源电路能够安装在芯片内,并且能够微型化使用该芯片构成的模块。与这些无源电路安装在芯片外的传统结构相比,能够大大缩短从芯片上的电路到每个无源电路的布线长度。能够抑制天线损耗,改善特别是RF电路中的频率特性。
