Description

电子封装件及其制法
技术领域
本发明有关一种封装制程,特别是关于一种能改善封装制程良率的电子封装件及其制法。
背景技术
贯穿胶体(Throughmoldingvia,简称TMV)的技术,目前已广泛运用于半导体领域,其主要技术利用激光烧灼方式于封装胶体表面进行开孔制程,以增加布线空间。例如,制作扇出型(Fan-Out,简称FO)封装堆迭(PackageonPackage,简称POP)结构时,便会使用该技术。
图1A至图1F为现有扇出型封装堆迭装置的其中一电子封装件1的制法的剖面示意图。
如图1A所示,设置一如晶片的电子元件10于一第一承载件18的离形层180上,再形成一绝缘层11于该离形层180上以覆盖该电子元件10。
如图1B所示,将具有铜箔190的第二承载件19设于该绝缘层11上。
如图1C所示,移除该第一承载件18及其离形层180,以露出该电子元件10与绝缘层11。
如图1D所示,以激光方式形成多个通孔110于该电子元件10周边的绝缘层11上。
如图1E所示,电镀铜材于该些通孔110中,以形成导电柱12,再于该绝缘层11上形成多个线路重布层(redistributionlayer,简称RDL)13,以令该线路重布层13电性连接该导电柱12与电子元件10。
如图1F所示,移除该第二承载件19,再利用该铜箔190进行图案化线路制程,以形成线路结构15,之后再进行切单制程。
随着该电子元件10的体积朝轻薄短小及功能性增强的趋势设计,所以需藉由增加该绝缘层11的厚度以提升该电子封装件1的可靠度。
但是,前述现有导电柱12的制法中,使用激光钻孔方式形成该通孔110,目前激光钻孔制程与电镀制程技术所能相互配合的深宽比小于1.25,所以增加该绝缘层11的厚度对于该通孔110的深宽比制作影响极大。例如,当该绝缘层11的厚度变厚(即该通孔110的深度H增加)时,若激光钻孔制程需将该通孔110的深宽比控制在小于1.25的范围内,则该通孔110的孔径(即宽度D)需增加(如第1D图的虚线),因而不符合细线距(finepitch)的需求;若将激光钻孔的深宽比提升至1.5,则当将铜材填入该些通孔110’中时,该通孔110’的底部无法镀满(即气室12’),如图1E’所示,因而影响后续封装制程良率,导致FOPOP制作成本太高。
此外,以激光方式形成该通孔110,于形成该通孔110的过程中所产生的残留物(如该绝缘层11的残胶)极易堆积于该通孔110的底部,所以需于后续制程中需先清洗该通孔110内部,才能将导电材料填入该通孔110中,但因增加该绝缘层11的厚度而使该通孔110的深度H增加,以致于难以完全清除该通孔110中的残留物,导致残留物会影响该导电柱12电性传输的良率。
因此,如何克服上述现有技术的种种问题,实已成目前亟欲解决的课题。
发明内容
鉴于上述现有技术的种种缺失,本发明提供一种电子封装件及其制法,以提升封装制程良率。
本发明的电子封装件,包括:绝缘层,其具有相对的第一表面与第二表面,且于该绝缘层中具有至少一第一穿孔和与该第一穿孔连通的第二穿孔,其中,该第一穿孔连通至该第一表面,该第二穿孔连通至第二表面;至少一电子元件,其嵌埋于该绝缘层中;至少一第一导电体,其对应并仅设于该第一穿孔中;以及第一线路结构,其设于该绝缘层的第一表面上,且该第一线路结构电性连接该电子元件与该第一导电体。
本发明还提供一种电子封装件的制法,其包括:提供一嵌埋有至少一电子元件的绝缘层,该绝缘层具有相对的第一表面与第二表面;于该绝缘层中形成连通至该第一表面的至少一第一穿孔;形成第一导电体于该第一穿孔中;形成第一线路结构于该绝缘层的第一表面上,且该第一线路结构电性连接该电子元件与该第一导电体;以及于该绝缘层中形成对应连通该第一穿孔和第二表面的第二穿孔,令该第一穿孔与第二穿孔构成通孔。
前述的制法中,该绝缘层以模压制程或压合制程形成者。
前述的制法中,该第一穿孔或第二穿孔以激光钻孔、机械钻孔或蚀刻方式形成者。
前述的电子封装件及其制法中,该电子元件具有相对的作用面与非作用面,且该作用面具有多个电极垫。例如,该第一表面与该作用面齐平;或者,该第二表面与该非作用面齐平。
前述的电子封装件及其制法中,该第一导电体为金属柱或金属球。
前述的电子封装件及其制法中,还包括形成第二线路结构于该绝缘层的第二表面上,且该第二线路结构电性连接该第一导电体,还可电性连接该电子元件。
前述的电子封装件及其制法中,还包括形成第二导电体于该第二穿孔中,且该第二导电体电性连接该第一导电体,而该第二导电体为金属柱。
另外,前述的电子封装件及其制法中,还包括堆迭电子封装结构于该绝缘层的第一表面或第二表面上。
由上可知,本发明的电子封装件及其制法中,藉由两阶段制程制作该通孔,所以可不受激光钻孔的深宽比限制,当该绝缘层的厚度变厚时,仍可将第一穿孔与第二穿孔的深宽比控制在小于1.25的范围内,而无需增加该第一穿孔与第二穿孔的孔径,以符合细线距的需求。
此外,由于该第一穿孔的深宽比无需增加,所以该第一导电体能有效镀满该第一穿孔。
又,因分别制作第一穿孔与第二穿孔,所以该第一穿孔的深度及第二穿孔的深度均小于该通孔的深度,因而容易清除该第一穿孔及第二穿孔中的残留物,以避免残留物影响该第一导电体或第二导电体电性传输的良率。
因此,本发明的制法能提升封装制程良率,以降低制作成本。

如图2C所示,形成第一导电体22于各该第一穿孔211中,再形成第一线路结构23于该绝缘层21的第一表面21a与该电子元件20的作用面20a上。
于本实施例中,该第一导电体22可利用电镀、沉积或其它现有技术形成如含铜、铝、钛、导电胶或其至少二者的组合的导电材于该第一穿孔211中。具体地,该第一导电体22为金属柱,例如铜柱;或者,如图2C’所示,该第一导电体22’也可为金属球,如铜材或焊锡材料。
此外,该第一线路结构23包含至少一介电层230、设于该介电层230上的一线路重布层(redistributionlayer,简称RDL)231、及设于该介电层230上并外露部分该线路重布层231的一绝缘保护层232,且该线路重布层231电性连接该电子元件20的电极垫200与该第一导电体22,22’。
又,该线路重布层231具有外露于该绝缘保护层232的多个电性接触垫233。
如图2D所示,于该绝缘层21中形成连通至第二表面21b的多个第二穿孔212,且各该第二穿孔212分别对应各该第一穿孔211的位置而与该第一穿孔211相通,令该第一穿孔211与第二穿孔212构成通孔210。
于本实施例中,该第二穿孔212以激光钻孔、机械钻孔、蚀刻或其它等方式形成者。
如图2E所示,形成第二导电体24于各该第二穿孔212中,再形成第二线路结构25于该绝缘层21的第二表面21b与该非作用面20b上。
于本实施例中,该第二导电体24电性连接该第一导电体22,且该第二导电体24可利用电镀、沉积或其它现有技术形成如含铜、铝、钛、导电胶或其至少二者的组合的导电材于该第二穿孔212中。具体地,该第二导电体24为金属柱,例如铜柱。
此外,该第二线路结构25包含至少一介电层250、设于该介电层250上的一线路重布层(redistributionlayer,简称RDL)251、及设于该介电层250上并外露部分该线路重布层251的一绝缘保护层252,其中,该线路重布层251藉由导电盲孔电性连接该第二导电体24,且该线路重布层251电性连接该电子元件20的非作用面20b以供散热,该线路重布层251并藉由该第二导电体24电性连接该第一导电体22。或者,如图2E’所示,该线路重布层251’形成于各该第二穿孔212中以直接电性连接该第一导电体22,而不需形成介电层250与第二导电体24。
又,该线路重布层251具有外露于该绝缘保护层252的多个电性接触垫253。
另外,也可不形成第二导电体24与第二线路结构25,也就是该通孔210并未填满金属材(只填有该第一导电体22’),如接续图2C’制程所得的图2E’所示的电子封装件2’。
于后续制程中,如图2F所示,形成多个如焊球、导电凸块的导电元件26于该第一线路结构23的电性接触垫233上。
或者,如图2G所示,藉由该些导电元件26堆迭该电子封装件2与一电子封装结构27,以形成一堆迭式电子封装件3,且该电子封装件2与该电子封装结构27藉由该些导电元件26而相互接触与电性连接。
于本实施例中,该电子封装结构27的构造与该电子封装件2的构造相同,藉以能堆迭多个该电子封装件2。
于另一实施例中,如图2G’所示,若堆迭多个如图2E’所示的电子封装件2’时,上方的电子封装件2’(可视为电子封装结构)的部分该些导电元件26将容置于下方的电子封装件2’的该些第二穿孔212中,使该些导电元件26接触并电性连接该第一导电体22’,藉以形成一堆迭式电子封装件3’。
此外,上方的电子封装件2’的部分该些导电元件26’可选择性接触或导通下方的电子封装件2’的电子元件20的非作用面20b以进行散热。
本发明的制法中,藉由两阶段制程(即制作第一穿孔211与第二穿孔212)制作该通孔210,所以可不受激光钻孔的深宽比限制,也就是当该绝缘层21的厚度变厚时,可将第一穿孔211与第二穿孔212的深宽比控制在小于1.25的范围内,而无需增加该第一穿孔211与第二穿孔212的孔径,以符合细线距(finepitch)的需求。
此外,由于该第一穿孔211的深宽比无需增加,所以该第一导电体22能有效镀满该第一穿孔211。
又,因分别制作第一穿孔211与第二穿孔212,所以该第一穿孔211的深度及第二穿孔212的深度均小于该通孔210的深度,因而容易清除该第一穿孔211及第二穿孔212中的残留物,以避免残留物影响该第一导电体22或第二导电体24电性传输的良率。
因此,本发明的制法能提升封装制程良率,以降低制作成本。
本发明提供一种电子封装件2,2’,3,3’,包括:一绝缘层21、至少一电子元件20、第一导电体22、以及第一线路结构23。
所述的绝缘层21具有相对的第一表面21a与第二表面21b,且于该绝缘层21中具有至少一第一穿孔211和与该第一穿孔211连通的第二穿孔212,其中,该第一穿孔211连通至该第一表面21a,该第二穿孔212连通至第二表面21b。
所述的电子元件20嵌埋于该绝缘层21中。
所述的第一导电体22,22’对应并仅设于该第一穿孔211中。该第一导电体22,22’为金属柱或焊锡凸块。
所述的第一线路结构23设于该绝缘层21的第一表面21a上,且该第一线路结构23电性连接该电子元件20的电极垫200与该第一导电体22,22’。
于一实施例中,所述的电子封装件2,3还包括形成于该绝缘层21的第二表面21b上的第二线路结构25,其电性连接该第一导电体22,且该第二线路结构25也可电性连接该电子元件20。
于一实施例中,所述的电子封装件2,3还包括对应形成于该第二穿孔212中的第二导电体24,其为金属柱并电性连接该第一导电体22。
于一实施例中,所述的电子封装件3,3’还包括堆迭于该绝缘层21的第一表面21a或第二表面21b上的电子封装结构27。
综上所述,本发明的电子封装件及其制法中,藉由两阶段制程制作该通孔,所以该通孔的深宽比可依需求调整,不仅能符合细线距的需求,且能提升该导电体的电性良率。
上述实施例仅用于例示性说明本发明的原理及其功效,而非用于限制本发明。任何本领域技术人员均可在不违背本发明的精神及范畴下,对上述实施例进行修改。因此本发明的权利保护范围,应如权利要求书所列。
