Description
相关申请的交叉引用
本申请基于并要求2004年9月10日申请的在先日本专利申请号2004-263412的优先权,在此引入其全部内容作为参考。
技术领域
本发明涉及一种半导体器件。
背景技术
近年来,为了改进信号延迟,已经提出了低阻抗的布线阻抗和低介电常数的层间绝缘膜。具体地说,通过将布线材料从Al变为Cu,使布线阻抗具有更低的阻抗。此外,通过应用低介电常数绝缘膜(低k膜)如掺氟的SiO2、含有机组分的SiO2膜、或代替SiO2的有机膜,以及进一步通过多孔性的低介电常数膜,使层间绝缘膜具有更低的介电常数。但是,另一方面,层间绝缘膜的介电常数的降低导致导热性下降的问题。具体地说,该多孔性导致层间绝缘膜内的热存储效应。
同时,由于半导体器件的速度增加和高集成度增加了功耗,并进一步增加了来自半导体芯片内部的热值。
由此,在目前的半导体芯片中,热值增加和热量趋于停留。因此,仅仅从Si衬底的背面散热,对散热来说是不够的,由此,导致芯片温度上升,并有可能导致工作故障,并进一步导致可靠性故障。
为解决这些散热问题,提出了通过在Si衬底的背面接合金属板或金属鳍状物来释放热量的方法。但是,其散热效果不够充分且需要更多的改进。
(例如,参考日本专利申请公开号平10-199882)提出了一种方法,其中在半导体芯片中形成多层虚布线,并通过虚过孔使虚布线彼此连接,以及通过虚布线传送热量,以从半导体芯片的表层释放热量。但是,半导体芯片的表层一般通过用于避免外界腐蚀和用于保护机械损坏的低寻热树脂密封。因此,在此情况下,热量还是保留在该半导体芯片中,且散热效果不够充分。
发明内容
根据本发明的一个方面,提供了一种半导体器件,该半导体器件包括:半导体芯片,在其内部具有第一金属导热介质;衬底,具有热连接到第一金属导热介质的第二金属导热介质;温度控制装置,其至少部分设置在所述衬上,热连接到第二金属导热介质,并设置为控制所述半导体芯片内的温度。
附图说明

图3是根据第一实施例的半导体芯片的示意性平面剖面图;
图4是根据第二实施例的半导体器件的示意性垂直剖面图。
具体实施方式
(第一实施例)
下面,将描述第一实施例。图1是根据本实施例的半导体器件的示意性垂直剖面图,图2是根据本实施例的半导体芯片的示意性垂直剖面图,图3是根据本实施例的半导体芯片的示意性平面剖面图。
如图1和图2所示,半导体器件1具有PBGA[FC](倒装芯片接合的塑料球栅阵列)封装结构。半导体器件1由半导体芯片10等构成。半导体芯片10包括半导体衬底11,在其上形成半导体元件(未示出)如晶体管。半导体芯片10可以具有由两个或更多半导体芯片构成的结构,如一个封装中的芯片上芯片结构。
在半导体衬底11上,形成用作实际布线的布线12,以及虚布线13(第一金属导热介质),其中虚布线13不用作实际布线但吸收半导体芯片10中的热量,然后将热量传递到之后描述的冷却模块54。
布线12包括布线层12A、12B、连接布线层12A和布线层12B的过孔12C、以及连接布线层12B和之后描述的电极焊盘17的过孔12D等。顺便提及,在图2中,示出了集成地形成的布线层12B和过孔12C,但是它们可以分开地形成。布线层12A、12B和过孔12C、12D由金属例如Cu等形成。
虚布线13包括虚布线层13A、13B、连接虚布线层13A和虚布线层13B的虚过孔13C、以及连接虚布线层13B和之后描述的虚电极焊盘18的虚过孔13D等。虚过孔13C、13D可以是与过孔12C、12D一样的圆柱形状,但是它们优选为如图2和图3所示在布线状态(wiring state)中形成的椭圆柱形状或图形。因此虚过孔13C、13D与之后描述的层间绝缘膜15、16的接触面积变大,以便可以从层间绝缘膜15、16吸收更多的热量。
顺便提及,在图2中,示出了集成地形成的虚布线层13B和虚过孔13C,但是它们可以分开地形成。虚布线层13A、13B和虚过孔13C、13D由金属,例如Cu、Al、Ag及其合金等构成。
布线12和虚布线13都具有镶嵌布线结构,并形成在层间绝缘膜14至16中。也就是说,布线层12A、12B分别形成在层间绝缘膜14、15上形成的布线沟槽中,以及过孔12C、12D分别形成在层间绝缘膜15、16中形成的通孔中。此外,虚布线层13A、13B分别形成在层间绝缘膜14、15上形成的虚布线沟槽中,以及虚过孔13C、13D分别形成在层间绝缘膜15、16中形成的虚通孔中。
布线12和虚布线13由层间绝缘膜14至16绝缘,以及虚布线13形成在与布线12隔开既不小于1μm也不超过5μm的位置处。这里,虚布线13形成在与布线1 2隔开既不小于1μm也不超过5μm的位置处的理由是因为如果距离小于1μm,那么可能影响光刻工艺和寄生电容量,如果距离超过5μm,那么通过虚布线13很难有效地吸收布线12的热量。而且,从寄生电容的观点,虚布线13的电位优选是地电位。
此外,在层间绝缘膜16上形成电极焊盘沟槽和虚电极焊盘沟槽。在电极焊盘沟槽中形成电连接到布线12的电极焊盘17,以及在虚电极焊盘沟槽中形成热连接到虚布线13的虚电极焊盘18。
对于层间绝缘膜14至16的构成材料,例如可以使用SiO2膜、低介电常数绝缘膜如有机Si氧化膜、有机树脂膜、多孔硅氧化膜等。低介电常数绝缘膜优选具有不超过3.0的介电常数(k)。对于电极焊盘17和虚电极焊盘18的构成材料,可以使用例如Al、Cu等。
在层间绝缘膜14至16和布线12之间、在层间绝缘膜14至16和虚布线13之间等形成用于抑制金属扩散到层间绝缘膜14至16的阻挡金属膜19。对于阻挡金属膜19的构成材料,可以使用例如Ta、Ti、TaN、TiN、NbN、WN、VN等。顺便提及,可以通过这些材料的层状材料形成阻挡金属膜19。
在层间绝缘膜14和层间绝缘膜15之间以及在层间绝缘膜15和层间绝缘膜16之间形成用于在化学机械抛光(CMP)的时候抑制过抛光的帽盖膜20。对于帽盖膜20的构成材料,可以使用例如基于SiO2的材料。顺便提及,在布线层12A、12B和虚布线层13A、13B上不形成帽盖膜20。
在帽盖膜20上,形成用于抑制金属扩散到作为上层的层间绝缘膜15、16的顶部阻挡膜21。对于顶部阻挡膜21的构成材料,例如可以使用SiCN等。顺便提及,在布线层12A、12B以及在虚布线层13A、13B上形成顶部阻挡膜21,但是在其上形成开口,以贯穿过孔12C、12D和虚过孔13C、13D。
在电极焊盘17上,形成电连接到电极焊盘17的凸块22,以及在虚电极焊盘18上,形成热连接到虚电极焊盘18的虚凸块23。对于凸块22和虚凸块23的构成材料,可以使用焊料或金属如Au。
在层间绝缘膜16上,形成钝化膜24和聚酰亚胺薄膜25。顺便提及,在钝化膜24上和在聚酰亚胺薄膜25上,形成开口,以贯穿凸块22和虚凸块23。
以面朝下的方式在封装衬底30上安装半导体芯片10。具体地说,凸块22电连接到在封装衬底30的上表面上形成的电极焊盘31,以及虚凸块23热连接到封装衬底30的上表面上形成的电极焊盘32。以此方式,将半导体芯片10的电极焊盘17和封装衬底30的电极焊盘31之间的连接和半导体芯片10的虚电极焊盘18和封装衬底30的虚电极焊盘32之间的连接,制造成使用例如凸块22和虚凸块23的相同的连接方式。因此,特别地,两者之间的电连接和热连接变得可以不导致制造工艺的复杂化。顺便提及,封装衬底30可以包括Si中间层(interposer)。
电极焊盘31通过封装衬底30的内部形成的布线33电连接到设置在封装衬底30的下表面处的BGA球34。虚电极焊盘32通过形成在封装衬底30的内部的虚布线35(第二金属导热介质)热连接到设置在封装衬底30的下表面处的虚BGA球36。对于布线33的构成材料,可以使用与布线12相同的构成材料。对于虚布线35的构成材料,可以使用与虚布线13相同的构成材料。
在半导体芯片10和封装衬底30之间,填充底充树脂40,以在加热周期期间吸收添加到凸块22等的应力,或防止凸块22等的疲劳破裂。
在封装衬底30的上表面,通过粘合剂42固定框架形状的增强板41,以便围绕半导体芯片10。此外,在增强板41的上表面上,通过粘合剂44固定覆盖板43,以便覆盖半导体芯片10。在半导体芯片10和覆盖板43之间填充热胶45,以便吸收半导体芯片10中的产生的热量并将它传递到覆盖板43。
在封装衬底30的下表面侧,设置冷却衬底(衬底)50。BGA球34通过在冷却衬底50的内部形成的布线51电连接到设置在冷却衬底50的下表面处的凸块52。虚BGA球36通过在冷却衬底50的内部形成的虚布线53(第二金属导热介质)热连接到设置在冷却衬底50中的冷却模块54(温度控制装置)的导管54A。
冷却模块54用于控制半导体芯片10的温度,并由导管54A构成,作为冷却模块的热交换器(未示出)设置为向导管54A提供冷却介质并设置为通过导管54A使冷却介质冷却等。对于冷却介质,例如,可以使用液体如水、液态氮、惰性气体等,或气体。
冷却模块54通过虚电极焊盘18等热连接到半导体芯片10中的虚布线13。顺便提及,在本实施例中,说明了冷却模块54用作温度控制装置时的情况,但是代替冷却模块54或与冷却模块54一起,可以使用热沉板,散热片,珀尔帖元件等。布线51由与布线12相同的金属构成,虚布线53由与虚布线13相同的金属构成。
在本实施例中,在半导体芯片10的内部形成虚布线13,分别在封装衬底30和冷却衬底50处形成热连接到虚布线13的虚布线35、53。而且,在冷却衬底50处设置热连接到虚布线53的导管54A。因此,通过虚布线13等可以将半导体芯片10内的热量安全地释放到半导体芯片10的外面。因此,可以提供具有高可靠性的半导体器件1。
在本实施例中,半导体芯片10内的热量通过虚凸块23释放到半导体芯片10的外面,因此可以阻止在电极焊盘17和凸块22处发生腐蚀。即,通过包含于气氛中的湿气和停留在电极焊盘17和凸块22中的热量在电极焊盘17和凸块22处可能发生腐蚀。但是,在本实施例中,半导体芯片10内的热量通过虚凸块23释放到外部,因此可以减小在电极焊盘17和凸块22中停留的热量。因此,可以阻止在电极焊盘17和凸块22处发生腐蚀。
在本实施例中,在半导体芯片10和覆盖板43之间插入热胶45。因此,从半导体芯片10的背面侧也可以进行散热。由此,可以提供具有更高可靠性的半导体器件1。
(实际例子)
下面,将说明实际例子。在本例子中,使用具有与第一实施例中的半导体芯片几乎相同结构的半导体芯片。层间绝缘膜由具有5GPa的杨氏模量、40ppm的线性膨胀系数以及约300nm厚度的低介电常数绝缘膜构成。阻挡金属膜由Ta/TaN的叠层膜构成,且厚度约为10nm。通过施加偏压的溅射形成阻挡金属膜。通过使用SIS(自电离溅射)方式溅射由粗糙膜变换(mat film conversion)形成70nm厚度的Cu籽晶膜来制造布线和虚布线,此后通过电解电镀形成Cu电镀膜,以及通过CMP除去不必要的电镀膜。顺便提及,布线状态中的过孔的直径和虚过孔的宽度是0.13μm。帽盖膜由d-TEOS构成,且其厚度为约50nm。电极焊盘和虚电极焊盘由Al构成,以及凸块和虚凸块由PbSn构成。
制备通过冷却衬底热连接到珀尔帖元件的这种半导体芯片的多个虚凸块,在150℃下进行高温工作测试,并检查工作故障率。这里,检查在高温工作测试过程中珀尔帖元件工作时和珀尔帖元件不工作时的各种工作故障率。当在高温工作测试期间珀尔帖元件工作时,珀尔帖元件设为约20℃。而且,通过在测试之后进行拆卸分析检查电极焊盘和凸块处的腐蚀的发生。顺便提及,对未形成虚布线的半导体芯片进行相同的测试。
下面,将描述该结果。对于其中未形成虚布线的半导体芯片,工作故障率是2000ppm。相反,对于其中形成了虚布线的半导体芯片,在高温工作测试过程中珀尔帖元件工作时未看到工作故障。此外,即使在高温工作测试过程中珀尔帖元件未工作时,工作故障率是500ppm。由此结果,证实当在半导体芯片中形成虚布线并且虚布线热连接到珀尔帖元件时,与未形成虚布线时的情况相比,散热效应高,很少发生半导体元件的工作故障。
根据测试之后的拆卸分析结果,当在半导体芯片中形成虚布线并在高温工作测试过程中珀尔帖元件工作时,或当在半导体芯片中形成虚布线并在测试过程中珀尔帖元件未工作时,在电极焊盘和凸块处未发生腐蚀,以及器件工作没有故障。而且,对于其中相对于虚布线每10μm设置0.13μm直径的虚过孔,代替布线状态中0.13μm宽度的虚过孔的半导体芯片进行相同的测试,可以获得相同的结果。因此,证实当用10μm以下的间隔设置虚过孔时,可以实现充分的散热。
(第二实施例)
下面,将描述第二实施例。顺便提及,与第一实施例多余的描述可以省略。图4是根据本实施例的半导体器件的示意性垂直剖面图。
如图4所示,半导体器件1具有EBGA(增强球栅阵列)封装结构。半导体芯片10设置在封装衬底60中。具体地说,在封装衬底60的中心部分处形成开口60A,以及在开口60A中设置半导体芯片10。半导体芯片10覆有铸封树脂61。
接合引线26电连接到代替凸块22的半导体芯片10的电极焊盘17,以及虚接合引线27热连接到代替虚凸块23的虚电极焊盘18。接合引线26通过在封装衬底60的内部形成的布线62电连接到封装衬底60的下表面处设置的BGA球63。虚接合引线27通过在封装衬底60的内部形成的虚布线64(第二金属导热介质)热连接到在封装衬底60的上表面处设置的热沉板65。热沉板65由金属构成。
在热沉板65中,设置冷却模块67的导管67A。冷却模块67具有与第一实施例中描述的冷却模块54相同的结构。在半导体芯片10和热沉板65之间填充热胶68。
在本实施例中,在半导体芯片10的内部形成虚布线13,在封装衬底60处形成热连接到虚布线13的虚布线64,以及在封装衬底60处设置热连接到虚布线64的热沉板65和导管67A。因此,与第一实施例一样,半导体芯片10内的热量可以安全地释放到半导体芯片10的外面,从而可以提供具有高可靠性的半导体器件1。
在本实施例中,在半导体芯片10和热沉板65之间插入热胶68。因此,可以从半导体芯片10的背面侧进行散热,以便可以提供具有更高可靠性的半导体器件1。
顺便提及,本发明不局限于上述实施例描述的内容,且在不脱离本发明的实质范围内可以进行结构、材料、每个部件的设置等的适当改变。例如,冷却模块54、67的导管54A、67A可以设置在封装衬底30、60中。此外,冷却模块54的导管54A可以设置在冷却衬底50的正面。而且,布线层12A、12B和虚布线层13A、13B的数目未被具体限制,且它们可以是任意数目的层。
