安装基片522可以是在本领域中已知的任何安装基片,例如印刷电路板(PCB)、主板、母板、夹层板、扩展卡或其他安装基片。在实施例中,热界面材料(TIM)526布置在管芯510的背侧表面514和集成散热器520之间。在实施例中,热界面材料526是根据在此披露中阐述的实施例的任何实施例的金属微粒组合物。在实施例中,热界面材料526是焊料。在实施例中,热界面材料526是反应金属微粒组合物,在回流处理期间它与背侧表面514化学地结合。在实施例中,热界面材料526是金属微粒组合物,例如金刚石填充焊料或碳纤维填充焊料。在实施例中,热界面材料是已回流的金属微粒组合物,包括小于或等于大约20μm的颗粒尺寸。
在实施例中,集成散热器520与结合材料528接附,结合材料528将集成散热器520的唇缘部分530固定在其上。微电子器件封装500的变化可以适合于使用数个金属微粒组合物实施例的一个。
图5B是进一步处理后的图5A中描绘的微电子器件封装501的截面。可以通过热处理进行将金属微粒组合物膏516(图5A)回流为焊料隆起焊盘517和金属微粒组合物热界面材料526的回流,或它们之一与管芯510连接。在实施例中,施加热以实现接近了或达到了特定的焊料隆起焊盘517或热界面材料526的固相线温度的温度。在实施例中,焊料隆起焊盘517或热界面材料526描绘为已加热到从大约150摄氏度到大约220摄氏度的范围。在实施例中,焊料隆起焊盘517或热界面材料526加热到从大约170摄氏度到大约200摄氏度的范围。在实施例中,焊料隆起焊盘517或热界面材料526加热到大约180摄氏度。在实施例中,平均颗粒尺寸在小于或等于大约20μm的范围内。
图6A是根据实施例在处理期间的微电子器件600的截面。基片610例如可以是为处理器的管芯,基片610包括用于从基片610到外界电连通的结合盘612。微电子器件600描绘为以带有图案的掩模614处理,掩模614暴露了结合盘612。在实施例中,结合盘612是铜的上金属化层,它可以接触数个金属化层的任一个。例如,在简单的微电子器件中的如金属一(M1,未绘出)的金属化层与结合盘612电接触。在另一个例子中,例如金属二(M2,未绘出)的金属化层与结合盘612电接触。M2与M1电接触。在另一个例子中,例如金属三(M3,未绘出)的金属化层与结合盘612电接触。M3与M2电接触,M2又与M1电接触。在另一个例子中,例如金属四(M4,未绘出)的金属化层与结合盘612电接触。M4与M3电接触。M3与M2电接触,M2又与M1电接触。在另一个例子中,例如金属五(M5,未绘出)的金属化层与结合盘612电接触。M5与M4电接触。M4与M3电接触。M3与M2电接触,M2又与M1电接触。在另一个例子中,例如金属六(M6,未绘出)的金属化层与结合盘612电接触。M6与M5电接触。M5与M4电接触。M4与M3电接触。M3与M2电接触,M2又与M1电接触。在另一个例子中,例如金属七(M7,未绘出)的金属化层与结合盘612电接触。M7与M6电接触。M6与M5电接触。M5与M4电接触。M4与M3电接触。M3与M2电接触,M2又与M1电接触。通过此披露,将清楚的是多种半导体基片结构可应用于多种实施例。
图6B是进一步处理后的图6A中描述的微电子器件601的截面。带有图案的掩模614在实施例中是带有图案的光致抗蚀剂,根据在此披露中阐述的多种实施例,它已填充有金属微粒组合物前体616,例如助熔的金属微粒组合物粉末616,也称为焊料微粒组合物膏616。
在实施例中,金属微粒组合物膏616包括在处理期间作为用于金属微粒组合物膏616的短效结合剂的助熔剂载体。在实施例中,本身不形成图案,而是助熔的金属微粒组合物形成敷层,且在回流期间助熔剂载体流化且优选地润湿结合盘612,且优选地变成疏基片610的,基片610可以是半导体、电介质和它们的组合。
图6C是进一步处理后的图6B中描述的微电子器件602的截面。在此实施例中,形成图案的掩模614已被去除。形成图案的掩模614的去除可以通过简单地将其从基片610拉离而完成,且因此留下了助熔的金属微粒组合物616,它形成为直接在结合盘612上的离散的孤立区。
图7是图6C中描绘的微电子器件的部分的放大。图7从图6C中描绘的虚线7内的区域取出。图7描绘了作为膏和助熔剂基质720内的金属微粒组合物718的金属微粒组合物前体。金属微粒组合物718包括在此披露中阐述的金属微粒组合物实施例的一个。因为膏和助熔剂基质720大体上保护了金属微粒组合物718不受腐蚀和/或氧化影响,所以金属微粒组合物718可以抵抗在回流期间大体上的颗粒生长。在实施例中,回流后金属微粒组合物718具有在小于或等于大约20微米(μm)的范围内的颗粒尺寸。因为微粒尺寸的实施例,微粒的晶核形成以从固相转变到固相线可以在大约400摄氏度或更低开始。例如,金可以在大约300摄氏度经历固相到固相线的转变。
图6D是进一步处理后的图6C中描述的微电子器件603的截面。已开始回流处理,在回流期间膏和助熔剂基质720(图7)已挥发,且金属微粒组合物718已回流为焊料隆起焊盘617(图6D),隆起617带有在小于或等于大约20μm的范围内的颗粒尺寸。描绘为用于微电子器件603的回流处理可以处于组装微电子器件封装的方法前,回流处理可以与微电子器件封装的其他热处理同时,或可以在组装微电子器件封装的一些元件之后,包括形成金属微粒组合物管芯接附实施例。随后讨论这些和其他的实施例。
图8A是在根据实施例的处理期间的微电子器件800的截面。器件800包括管芯810,管芯810包括多个管芯结合盘812。器件800也包括根据在此披露中阐述的金属微粒组合物实施例的任何实施例的金属微粒组合物814。管芯810通过金属微粒组合物814联接到安装基片816,金属微粒组合物814用作它们之间的电气隆起。管芯810到安装基片816的电气联接通过安装基片结合盘818完成,安装基片结合盘818与多个管芯结合盘812对齐。通过多个板隆起实现对微电子器件800的进一步的连通,隆起的一个以参考数字820标识。
图8B是进一步处理后的图8A中描述的微电子器件800的截面。包括安装基片816上的管芯810的微电子器件801已安装在板822上。在实施例中,板822已通过板隆起820结合到安装基片816。在实施例中,板隆起820包括在此披露中阐述的任何金属微粒组合物实施例。
在此披露中阐述的电气隆起的实施例也可应用于线结合技术。因为熔点在大约400摄氏度或更低的范围内开始,线结合的处理可以在条件下进行以保持线结合器件的热预算。
图9是根据多种实施例的处理流程图900。助熔的金属微粒组合物的处理分别在形成管芯接附和/或焊料隆起焊盘的过程期间和已封装的管芯的组装方法期间进行。在910处,助熔的金属微粒组合物实施例在管芯上形成图案。通过在图4中的图示,管芯接附金属微粒组合物412用于将管芯410接附到安装基片414。通过在图6B中的进一步图示,形成有图案的掩模614已填充有助熔的金属微粒组合物616。
在920处,助熔的焊料微粒组合物实施例在管芯上回流。通过在图5B中的图示,在比作为宏观体积材料的单独金属的熔化温度显著地更低的温度下,已回流的金属微粒隆起517、已回流的热界面材料526被描绘为形成金属组合物。在921处,处理流程可以从助熔的金属微粒合成物回流的处理处向将管芯组装到封装内的方法前进。在922处,一个处理实施例完成。
选择地在线结合技术中,在管芯上对助熔的金属微粒组合物粉末形成图案的处理在将线结合焊料隆起焊盘放置在管芯上期间逐一地实现。
在930处,包括焊料或助熔的金属微粒组合物的管芯被组装到封装内。通过图示,图5A和图5B描绘了管芯510与至少安装基片522的组装。在实施例中,集成散热器520或其他散热基片也与助熔的金属微粒组合物514或焊料隆起焊盘517和管芯510组装。在931处,处理流程可以从将管芯组装到封装的方法前进,随后是将金属微粒组合物回流为管芯接附和/或回流为焊料隆起焊盘的处理。在932处,一个方法实施例完成。
图10是描绘了根据实施例的计算系统1000的截取正视图。一个和多个前述的金属微粒组合物、管芯接附组合物和/或焊料隆起焊盘组合物的实施例可用利用在计算系统中,例如图10的计算系统1000。在后文中,任何单独的实施例或与任何其他实施例组合的实施例被称为金属微粒组合物实施例。
计算系统1000例如包括至少一个封闭在封装1010内的处理器(未示出)、数据存储系统1012、至少一个例如键盘1014的输入设备和至少一个例如监视器1016的输出设备。计算系统1000包括处理数据信号的处理器,且可以包括例如从Intel Corporation可获得的微处理器。除键盘1014外,计算系统1000可以包括另外的使用者输入设备,例如鼠标1018。计算系统1000可以与包括管芯、安装基片和板的器件400、501和801的任何器件相对应。因此,封装1010(包括管芯)和板1020可以对应于这些结构。
为此披露的目的,实施了根据要求的主题的部件的计算系统1000可以包括任何利用了微电子器件系统的系统,其可以包括例如联接到例如动态随机存取存储器(DRAM)、聚合物存储器、闪速存储器和相变存储器的数据存储器的金属微粒组合物实施例的至少一个。在此实施例中,金属微粒组合物实施例通过联接到处理器而联接到这些功能性的任何组合。然而,在实施例中,在此披露中阐述的金属微粒组合物实施例联接到这些功能性的任何功能性。对于作为例子的实施例,数据存储器包括管芯上的嵌入式DRAM高速缓冲存储器。另外,在实施例中,联接到处理器(未示出)的金属微粒组合物实施例是系统的部分,系统带有联接到DRAM高速缓冲存储器的数据存储器的金属微粒组合物的实施例。另外,在实施例中,金属微粒组合物实施例联接到数据存储器1012。
在实施例中,计算系统也可以包括管芯,管芯包括数字信号处理器(DSP)、微控制器、专用集成电路(ASIC)或微处理器。在此实施例中,金属微粒组合物实施例通过联接到处理器而联接到这些功能性的任何组合。对于作为例子的实施例,DSP(未示出)是芯片组的部分,其可以包括独立式处理器(在封装1010内)和DSP作为板1020上的芯片组的分开的部分。在此实施例中,金属微粒组合物实施例联接到DSP,且可以存在分开的金属微粒组合物实施例,它联接到封装1010内的处理器。另外,在实施例中,金属微粒组合物实施例联接到与封装1010安装在相同的板1020上的DSP。现在可以认识到,如对于计算系统1000所阐述地,金属微粒组合物实施例可以结合通过此披露及其等价物的多种实施例阐述的金属微粒组合物实施例组合。
在此披露中阐述的金属微粒组合物实施例可以应用于不同于传统的计算机的设备和器械。例如,管芯可以以金属微粒组合物实施例封装,且放置在例如无线通信器的便携式设备或如个人数字助理等的手持设备内。另一个例子是可以以金属微粒组合物实施例封装且放置在例如汽车、机车、航水器、航空器或航天器的交通工具中的管芯。
