如图9所示,可以通过本领域任何已知技术将诸如铜、铝、银、金及其合金的导电材料设置在开口154内,以形成第一微电子器件接触连接盘第一导电通孔166a、第一微电子器件接触连接盘第二导电通孔166b、第一层叠封装焊盘导电通孔162a、第二层叠封装焊盘导电通孔162b、第一次级器件焊盘导电通孔164a以及第二次级器件焊盘导电通孔164b。同时,还可以将导电材料设置在开口154'内,以形成第二微电子器件接触连接盘第一导电通孔166a'、第二微电子器件接触连接盘第二导电通孔166b'、第三层叠封装焊盘导电通孔162a'、第四层叠封装焊盘导电通孔162b'、第三次级器件焊盘导电通孔164a'以及第四次级器件焊盘导电通孔164b'。如图9进一步所示的,可以形成导电迹线,以电连接各个导电通孔。如图所示,可以形成第一导电迹线168a,以将第一次级器件焊盘导电通孔164a和第一微电子器件接触连接盘第一导电通孔166a电连接,并且可以形成第二导电迹线168b,以将第二次级器件焊盘导电通孔164b和第一微电子器件接触连接盘第二导电通孔166b电连接。此外,可以形成第三导电迹线168a',以将第三次级器件焊盘导电通孔164a'和第二微电子器件接触连接盘第一导电通孔166a'电 连接,并且可以形成第四导电迹线168b',以将第四次级器件焊盘导电通孔164b'和第二微电子器件接触连接盘第二导电通孔166b'电连接。因此,各导电通孔和导电迹线的连接在次级器件焊盘与微电子器件之间形成导电通路。导电迹线(例如,元件168a、168b、168a'和168b')可以是任何合适的导电材料,其包括但不限于铜、铝、银、金及其合金。
应当理解,可以构建额外的介电层、导电通孔和导电迹线,以形成期望数量的层。一旦形成了期望数量的层,就可以形成外层,例如,玻璃布层。如图9所示,可以在第一介电层152上形成第一外层172,并可以在第二介电层152'上形成第二外层172'。可以采用外层(即,第一外层172和第二外层172')设计微电子封装中的内在挠曲/应力,这是本领域技术人员所能够理解的。
因此,可以采用去板(depaneling)工艺使形成于载体第一表面108和载体第二表面108'上的结构相互分离。图10示出了在去板之后在载体第一表面108上形成的结构。如图11所示,可以例如通过等离子灰化或溶剂释放来去除第一牺牲材料层110,这是本领域技术人员能够理解的。还可以通过本领域任何合适的已知技术来去除保护层120,也如图11所示。如图12所示,可以例如通过等离子灰化或者化学溶解将粘合层144从第一微电子器件142去除,以形成微电子器件封装180。应当理解,如果采用等离子灰化去除第一牺牲材料层110,则也可以在单个等离子灰化步骤中去除粘合层144。

如图30所示,可以形成贯穿第一牺牲材料层310的开口332,以暴露出第一支座材料层310的一部分和载体第一表面108的一部分,并且可以同时在第二牺牲材料层310'中形成开口332',以暴露出第二牺牲材料层310'的一部分和载体第二表面108'的一部分。可以通过本领域任何已知技术来形成第一牺牲材料层开口332和第二牺牲材料层开口332',该已知技术包括但不限于光刻图案化和显影。应当理解,如果将光致抗蚀剂材料用于支座材料层和牺牲材料层,则如图28所示,使第一支座材料层302和第二支座材料层302'发生交联可导致在第一牺牲材料层开口332和第二牺牲材料层开口332'的形成期间而基本未受影响的第一支座材料层302和第二支座 材料层302'。
如图31所示,可以采用粘合材料344使第一微电子器件342通过其背面350附着到在第一牺牲材料层开口332内的载体第一表面108。第一微电子器件342可以具有在其活性表面348上的至少一个接触连接盘(被示为元件346a和346b)。可以采用粘合材料344'使第二微电子器件342'通过背面350'附着到在第二牺牲材料层开口332'内的载体第二表面108'。第二微电子器件342'可以具有在其活性表面348'上的至少一个接触连接盘(被示为元件346a'和346b')。微电子器件可以是任何期望的器件,其包括但不限于微处理器(单芯或多芯)、存储器件、芯片组、图形器件、专用集成电路等。
随后,可以使至少一个次级器件附着到相应的支座材料。如图31进一步所示,可以采用粘合材料376a将第一次级器件374a附着到第一支座材料层302,可以采用粘合材料376b将第二次级器件374b附着到第一支座材料层302,可以采用粘合材料376a'将第三次级器件374a'附着到第二支座材料层302',并可以采用粘合材料376b'将第四次级器件374b'附着到第二支座材料层302b'。
如图32所示,可以在第一微电子器件342、第一次级器件374a和第二次级器件374b上形成第一介电层352。同时,可以在第二微电子器件342'、第三次级器件374a'和第四次级器件374b'上形成第二介电层352'。而且,如图32所示,可以在第一介电层352中形成多个开口354,以暴露出每一开口354的相应下列中的至少一部分:微电子器件接触连接盘346a和346b、第一次级器件374a、以及第二次级器件374b。可以在第二介电层352'中形成多个开口354',以暴露出每一开口354'的相应下列中的至少一部分:微电子器件接触连接盘346a'和346b'、第三次级器件374a'、或者第四次级器件374b'。在一个实施例中,第一介电层352和第二介电层352'可以包括填充了二氧化硅的环氧树脂。可以通过本领域任何已知技术来形成开口354和354',该已知技术包括但不限于激光钻孔、离子钻孔、蚀刻等。
如图33所示,可以通过本领域任何已知技术将导电材料设置在第一介电材料层开口354(参见图32)内,以形成第一微电子器件接触连接盘第一导电通孔366a、第一微电子器件接触连接盘第二导电通孔366b、第一次级器件第一导电通孔3641a、第一次级器件第二导电通孔3642a、第二次级 器件第一导电通孔3641b和第二次级器件第二导电通孔3642b。同时,还可以将导电材料设置在第二介电材料层开口354'(参见图32)内,以形成第二微电子器件接触连接盘第一导电通孔366a'、第二微电子器件接触连接盘第二导电通孔366b'、第三次级器件第一导电通孔3641a'、第三次级器件第二导电通孔3642b'、第四次级器件第一导电通孔3641b'和第四次级器件第二导电通孔3642b'。如图33进一步所示,可以形成导电迹线,以电连接各个导电通孔。如图所示,可以形成第一导电迹线368a,以将第一次级器件第一导电通孔3641a和第一次级器件第二导电通孔3642a中的至少之一与第一微电子器件接触连接盘第一导电通孔366a电连接。可以形成第二导电迹线368b,以将第二次级器件第一导电通孔3641b和第二次级器件第二导电通孔3642b中的至少之一与第一微电子器件接触连接盘第二导电通孔366b电连接。此外,可以形成第三导电迹线368a',以将第三次级器件第一导电通孔3641a'和第三次级器件第二导电通孔3642a'中的至少之一与第二微电子器件接触连接盘第一导电通孔366a'电连接。可以形成第四导电迹线368b',以将第四次级器件第一导电通孔3641b'和第四次级器件第二导电通孔3642b'中的至少之一与第二微电子器件接触连接盘第二导电通孔366b'电连接。因而,各导电通孔和导电迹线的连接在次级器件焊盘和微电子器件之间形成导电通路。导电迹线(例如,元件368a、368b、368a'和368b')可以是任何合适的导电材料。
应当理解,可以构建额外的介电层、导电通孔和导电迹线,以形成期望数量的层。一旦形成了期望数量的层,就可以形成外层,例如,玻璃布层。如图33所示,可以在第一介电层352上形成第一外层372,并可以在第二介电层352'上形成第二外层372'。可以采用外层(即,第一外层372和第二外层372')来设计微电子封装中的内在挠曲/应力,这是本领域技术人员所能够理解的。
可以采用去板工艺使如此形成在载体第一表面108和载体第二表面108'上的结构相互分离,这是本领域已知的。图34示出了在去板之后在载体第一表面108上形成的结构。
如图35所示,可以例如通过溶剂释放来去除第一支座材料层302和第一牺牲材料层310。随后,可以如图36所示,例如通过等离子灰化来去除 第一微电子器件粘合材料层344、第一次级器件粘合材料376a和第二次级器件粘合材料376b(参见图34),以形成微电子器件封装380。
应当理解,可以采用受控等离子灰化同时去除第一支座材料层302、第一牺牲材料层310、第一微电子器件粘合材料层344、第一次级器件粘合材料376a、以及第二次级器件粘合材料376b。还应当理解,可以采用受控的等离子灰化来去除第一支座材料层302、第一微电子器件粘合材料层344、第一次级器件粘合材料376a、以及第二次级器件粘合材料376b,同时如图37所示将第一牺牲材料层310保留在原位,以形成微电子器件封装390。
从图36和37可以看出,图26-37的过程可以得到设置在第一微电子器件342的厚度T内(即,在第一微电子器件活性表面348和第一微电子器件背面350之间)的次级器件(例如,元件374a和374b)。
尽管图28-37中所示的实施例在为微电子器件封装而形成的支座层中示出,但是应当理解,可以形成多重支座材料层,并且可以在这些材料内形成各种凹穴或空腔,从而创建出各种封装架构,以实现微电子器件和封装堆叠以及多器件嵌入,这是本领域技术人员所能够理解的。
应当理解,本说明书的主题未必局限于图1-37中所示的具体应用。可以将所述主题应用于其它微电子器件封装应用。此外,还可以将所述主题用到微电子器件制造领域以外的任何合适应用中。此外,本说明书的主题可以是较大的内建无凹凸封装的部分,其可以包括多个堆叠的微电子裸片,其可以以晶片级来形成或以任何数量的合适变化来形成,这是本领域技术人员所能够理解的。
尽管已经详细描述了本发明的实施例,但是应当理解,由所附权利要求限定的本发明不受上述说明书中阐述的具体细节的限制,在不背离本发明的精神和范围的基础上可以存在很多明显的变化。
