Description

半導體封裝結構
本發明涉及半導體技術領域,尤其涉及一種半導體封裝結構。
隨著對具有更多功能的更小裝置的需求增加,垂直堆疊兩個或更多半導體晶片或半導體晶粒的三維積體電路(three-dimensional integrated circuit,3D IC)封裝技術變得越來越流行。 3D IC封裝技術採用引線接合(wire bonding)、倒裝晶片(flip chip)等互連方式實現垂直堆疊。因此,在 3D IC 封裝中,可以降低製造成本,並且可以在比傳統二維 (two-dimensional,2D) IC 封裝技術更低的功率和更小的佔用空間下實現性能改進。
然而,雖然現有的半導體封裝結構通常是足夠的,但是它們在各個方面都不是令人滿意的。 3D IC 封裝技術帶來了新的挑戰,例如熱(thermal)或供電網路 (power delivery network,PDN) 設計問題。這些問題降低了半導體封裝結構的可靠性。因此,需要進一步改進半導體封裝結構。
有鑑於此,本發明提供一種半導體封裝結構,以解決上述問題。
根據本發明的第一方面,公開一種半導體封裝結構,包括: 正面重分佈層; 第一半導體晶粒,設置在該正面重分佈層上方; 第一電容器,設置在該正面重分佈層上方並電耦接到該第一半導體晶粒; 導電端子,設置在該正面重分佈層下方並電性連接至該正面重分佈層;以及 背面重分佈層,設置在該第一半導體晶粒上方。
根據本發明的第二方面,公開一種半導體封裝結構,包括: 基板,具有佈線結構; 半導體晶粒,設置在該基板上方並電耦接到該佈線結構; 凸塊結構,鄰近該半導體晶粒; 模制材料,圍繞該半導體晶粒和該凸塊結構;以及 電容器結構,設置在該模制材料上並透過該凸塊電耦和該佈線結構耦接到該半導體晶粒。

根據本發明的一些實施例描述了包括電容器的半導體封裝結構。與去除部分導電端子為電容器提供空間的實施例相比,本發明實施例可以保留更多的導電端子。此外,在一些實施例中,可以降低製造半導體封裝結構的複雜性。
圖1A是根據本發明的一些實施例的半導體封裝結構100的截面圖。可以向半導體封裝結構100添加附加特徵。對於不同的實施例,可以替換或消除下面描述的一些特徵。為簡化示意圖,僅繪示半導體封裝結構100的一部分。
如圖1A所示,根據一些實施例,半導體封裝結構100包括重分佈層,重分佈層可以包括複數個導電層RDL1、RDL2、RDL3和RDL4。僅出於說明的目的示出四個導電層RDL1、RDL2、RDL3和RDL4,並且可以存在多於或少於四個導電層。
在一些實施例中,重分佈層包括複數個鈍化層(在圖1A中省略而未示出),並且導電層RDL1、RDL2、RDL3和RDL4設置在鈍化層中。導電層RDL1、RDL2、RDL3和RDL4可以透過鈍化層中的複數個導電通孔116彼此電耦接。
導電層RDL1、RDL2、RDL3和RDL4可以由金屬形成,例如銅、鈦、鎢、鋁等或其組合。導電通孔116可由金屬形成,例如銅、鈦、鎢、鋁等或其組合。
在一些實施例中,鈍化層包括聚合物層,例如聚醯亞胺(polyimide,PI)、聚苯並惡唑(polybenzoxazole,PBO)、苯並環丁烯(benzocyclobutene,BCB)、環氧樹脂等或其組合。或者,鈍化層可包括介電層,例如氧化矽、氮化矽、氮氧化矽等或其組合。
如圖1A所示,根據一些實施例,半導體封裝結構100包括垂直堆疊在重分佈層上方的第一半導體晶粒102和第二半導體晶粒104。第一半導體晶粒102和第二半導體晶粒104也可以分別稱為頂部半導體晶粒102和底部半導體晶粒104。
根據一些實施例,第一半導體晶粒102和第二半導體晶粒104各自獨立地包括系統單晶粒(system-on-chip,SoC)晶粒、邏輯器件、記憶體器件、射頻(radio frequency,RF)器件之類,或它們的任何組合。

根據一些實施例,半導體封裝結構100還包括一個或複數個無源元件(未示出),例如電阻器、電容器、電感器或其組合。
如圖1A所示,第一半導體晶粒102可以具有XPU核(core)106,並且第二半導體晶粒104可以具有XPU核108。第二半導體晶粒104的XPU核108可以電耦接到XPU核108重分佈層。第二半導體晶粒104可以在其中具有通孔。第一半導體晶粒102的XPU核106可以透過第二半導體晶粒104中的通孔電耦接到重分佈層。
如圖1A所示,根據一些實施例,半導體封裝結構100包括設置在重分佈層下方的多端子多電容器結構110。多端子多電容器結構110可以具有複數個端子112,並且可以透過重分佈層和端子112電耦接到第一半導體晶粒102和第二半導體晶粒104。
多端子多電容器結構110可以具有一個以上電容器和一個以上端子112,其中這些電容器分別電耦接到第一半導體晶粒102和第二半導體晶粒104。也就是說,多端子多電容器結構110可以是多電容器結構。
與半導體封裝結構包括用於第一半導體晶粒102和第二半導體晶粒104的單獨電容器的實施例相比,半導體封裝結構100使用多端子多電容器結構110用於第一半導體晶102和第二半導體晶104,可以減少佔用的空間。此外,可以提高設計靈活性。
如圖1所示,第一半導體晶粒102和第二半導體晶粒104可以在與第一半導體晶粒102和第二半導體晶粒104的堆疊方向基本平行的方向上重疊多端子多電容器結構110。
在一些實施例中,兩個半導體晶粒,第一半導體晶粒102和第二半導體晶粒104,共用一個多端子多電容器結構110,但本發明不限於此。例如,多於兩個半導體晶粒可共用多端子多電容器結構110。或者,多於一個多端子多電容器結構可用於複數個半導體晶粒。
圖1B是根據一些實施例的半導體封裝結構100的多端子多電容器結構110的俯視圖。如圖1B所示,多端子多電容器結構110可包括複數個第一端子112a、複數個第二端子112b以及複數個接地端子112c。
第一端子 112a 可以電耦接到第一半導體晶粒 102 的電源端子。第二端子 112b 可以電耦接到第二半導體晶粒 104 的電源端子。接地端子112c可以電耦接到第一半導體晶粒102和第二半導體晶粒104的接地端子。特別地,第一半導體晶粒102的接地端子和第二半導體晶粒104的接地端子可以彼此連接並且接地。 或者,第一半導體晶粒102的接地端子和第二半導體晶粒104的接地端子可以分別接地。
在一些實施例中,第一端子112a可以沿著第一條線佈置,第二端子112b可以沿著第二條線佈置,並且接地端子112c可以沿著第三條線佈置。第一條線、第二條線和第三條線可以彼此平行。
接地端子112c可以設置在一行(column)第一端子112a和一行第二端子112b之間以及兩行第二端子112b之間。圖中所示的第一端子112a、第二端子112b和接地端子112c的數量和排列方式僅為示例性的,並不用於限制本發明。例如,第一端子112a可以沿著兩條線佈置,並且接地端子112c可以設置在兩行第一端子112a之間。
返回參考圖 1A,根據一些實施例,半導體封裝結構 100 包括複數個導電端子 114,其設置在重分佈層下方並與多端子多電容器結構 110 相鄰。即,多端子多電容器結構110可以設置在導電端子114之間。
導電端子114可以電耦接到重分佈層。在一些實施例中,導電端子114由導電材料形成,例如金屬。導電端子114可包括微凸塊、受控塌陷晶片連接(controlled collapse chip connection,C4)凸塊、焊球、球柵陣列(ball grid array,BGA)球等或其組合。
如圖1A所示,多端子多電容器結構110可佔據導電端子114的面積。此外,由於第一半導體晶粒102與第二半導體晶粒104垂直堆疊且投影面積相同根據資源,第一半導體晶粒102和第二半導體晶粒104下方的可用導電端子114的數量可以少於並排佈置的半導體晶粒。
隨著對更多功能和更小裝置的需求不斷增加,這些問題增加了整合用於不同半導體晶粒的單獨電容器的難度。有鑑於此,本發明的半導體封裝結構100採用多端子多電容器結構110代替單獨的電容,可減少電容的佔用面積,並可保留更多的導電端子114。
圖2A是根據本發明的一些實施例的半導體封裝結構200的截面圖。需要說明的是,半導體封裝結構200可以包括與圖1所示的半導體封裝結構100相同或相似的元件,為簡單起見,不再贅述。在以下實施例中,多端子多電容器結構設置在基板下方。

需要說明的是,圖中所示的基板202的配置僅為示例性的,並不用於限制本發明。可以在基板202中和基板202上形成任何期望的半導體部件。然而,為了簡化圖示,僅示出了平坦基板202。
如圖2A所示,根據一些實施例,半導體封裝結構200包括設置在基板202下方的多端子多電容器結構210。多端子多電容器結構210可具有複數個端子212,並且透過重分佈層、導電端子114、基板202中的佈線結構以及端子212電性連接至第一半導體晶粒102和第二半導體晶粒104。
多端子多電容器結構210可以具有一個以上電容器和一個以上端子212,其中這些電容器分別電耦接到第一半導體晶粒102和第二半導體晶粒104。也就是說,多端子多電容器結構210可以是多電容器結構。
如上所述,根據一些實施例,半導體封裝結構200使用多端子多電容器結構210用於第一半導體晶粒102和第二半導體晶粒104可以減少佔用的空間並提高設計靈活性。本實施例中可以同時使用多端子多電容器結構110和多端子多電容器結構210,因此進一步減少了空間的佔用,提高了設計靈活性。

第一端子212a、第二端子212b和接地端子212c可以類似於圖1B所示的第一端子112a、第二端子112b和接地端子112c,在此不再贅述。

圖3是根據本發明的一些實施例的半導體封裝結構300的截面圖。需要說明的是,半導體封裝結構300可包括與圖1所示的半導體封裝結構100相同或相似的元件,為簡單起見,不再贅述。在以下實施例中,電容器設置在背面重分佈層上,以在正面重分佈層上保留更多的導電端子。正面重分佈層可以是設置在晶粒具有導電焊盤的一端的重分佈層。
如圖3所示,根據一些實施例,半導體封裝結構300包括垂直堆疊的第一封裝結構300a和第二封裝結構300b。第一封裝結構300a可以具有正面和與正面相對的背面。在一些實施例中,第一封裝結構300a具有設置在正面上的正面重分佈層302和設置在背面上的背面重分佈層324。
正面重分佈層302可以包括一個或複數個導電層和鈍化層,其中導電層可以設置在鈍化層中。導電層可包括金屬,例如銅、鈦、鎢、鋁等或其組合。

雖然在圖3中示出了兩個半導體晶粒,第一半導體晶粒312和第二半導體晶粒306,但是可以存在一個或多於兩個的半導體晶粒。例如,第一封裝結構300a可以包括垂直堆疊的三個半導體晶粒。或者,第一封裝結構300a可以包括四個半導體晶粒,其中兩個半導體晶粒垂直堆疊在半導體晶粒上方,並且另一個半導體晶粒佈置在半導體晶粒上方並且與兩個半導體晶粒相鄰。

如圖3所示,根據一些實施例,第一封裝結構300a包括圍繞第一半導體晶粒312的模制材料(或模塑料)316。模制材料316可以覆蓋第二半導體晶粒306的頂面(或上表面)並且可以鄰接第一半導體晶粒312的側壁。模制材料316可以保護第一半導體晶粒312免受環境影響,從而防止第一半導體晶粒312由於例如應力、化學品和/或濕氣而損壞。
模制材料316可以包括非導電材料,例如可模制聚合物、環氧樹脂、樹脂等,或它們的組合。在一些實施例中,模制材料316以液體或半液體形式施加,然後透過任何合適的固化過程固化,固化過程例如包括熱固化過程、UV固化過程等,或其組合。模制材料316可以用模具(未示出)成形或模制。
然後,可以透過平坦化製程例如化學機械拋光(chemical mechanical polishing,CMP)部分地去除模制材料316,直到暴露第一​​半導體晶粒312的頂面。在一些實施例中,模制材料316的頂面和第一半導體晶粒312的頂面基本上共面。如圖3所示,模制材料316的側壁可以與第二半導體晶粒306的側壁基本共面。

圖中所示的導電柱318的配置僅是示例性的,並不旨在限制本發明。例如,在第一半導體晶粒312和第二半導體晶粒306的相對側上,導電柱318的數量可以不同。或者,導電柱318可以設置在第一半導體晶粒312和第二半導體晶粒306的一側上。
如圖3所示,根據一些實施例,第一封裝結構300a包括圍繞第一半導體晶粒312、第二半導體晶粒306、模制材料316和導電柱318的模制材料322。模制材料322可以鄰接第二半導體晶粒306的側壁和模制材料316,並且可以覆蓋正面重分佈層302的頂面和背面重分佈層324的底面(下表面)。
如圖3所示,模制材料322可以填充導電柱318之間以及第一半導體晶粒312和第二半導體晶粒306與導電柱318之間的間隙。模制材料322可以保護半導體晶粒312、第二半導體晶粒306和導電柱318免受環境影響,從而防止這些部件由於例如應力、化學製品和/或濕氣而損壞。
在一些實施例中,模制材料322包括非導電材料,例如可模制聚合物、環氧樹脂、樹脂等,或它們的組合。在一些實施例中,模制材料322以液體或半液體形式施加,然後透過任何合適的固化過程固化,例如熱固化過程、UV固化過程等,或其組合。模制材料322可以用模具(未示出)成形或模制。
然後,可以透過諸如化學機械拋光(CMP)的平坦化製程部分地去除模制材料322,直到暴露導電柱318的頂面。在一些實施例中,模制材料322的頂面和導電柱318的頂面基本上共面。如圖3所示,模制材料322的側壁可以與正面重分佈層302的側壁和背側重分佈層324的側壁基本共面。在一些其他實施例中,可以省略模制材料316,並且模制材料322可以鄰接第一半導體晶粒312的側壁。
如圖3所示,根據一些實施例,背面重分佈層324設置在第一半導體晶粒312上方。背面重分佈層324可以覆蓋第一半導體晶粒312的頂面、模制材料316的頂面、導電柱318的頂面和模制材料322的頂面。
如圖所示參照圖3,根據一些實施例,第一封裝結構300a包括設置在背面重分佈層324下方並由模制材料322圍繞的電容器320。電容器320可以設置在導電柱318和第一半導體晶粒312之間。
如圖3所示,電容器320可以與背面重分佈層324接觸並且透過模制材料322與正面重分佈層302間隔開。電容器320可以具有複數個端子320t,並且可以透過端子320t、背面重分佈層324和通孔314電耦接到第一半導體晶粒312。
與具有焊盤側電容(電容器位於晶粒的焊盤的一側或附近)的半導體封裝結構相比,根據本發明的半導體封裝結構300具有不佔用導電端子304空間的電容器320,可以增加設計的靈活性。電容器320設置在模制材料322內可以節省空間的佔用,利用第一半導體晶粒312與導電柱318之間間隙來佈置電容器320,充分利用了閒置空間,提高了空間利用率。
在其他一些實施例中,電容器320為多電容器結構,例如為如圖1所示的多端子多電容器結構110,在此不再贅述。在這些實施例中,電容器320可以電耦接到第一半導體晶粒312,並且還可以透過第一半導體晶粒312中的端子320t、背面重分佈層324、通孔314以及第二半導體晶粒306中的通孔308電耦接到第二半導體晶粒306。
在電容器310是電耦接第一半導體晶粒312和第二半導體晶粒306的多電容器結構的實施例中,可以省略電容器320。類似地,在電容器320是電耦接第一半導體晶粒312和第二半導體晶粒306的多電容器結構的實施例中,電容器310可以用導電端子304代替。
或者,在一些實施例中,電容器310和電容器320中的至少一個是多電容器結構,並且第一封裝結構300a可以包括兩個以上的半導體晶粒,該半導體晶粒可以電耦接到電容器310和電容器 320。

圖5B是根據一些實施例的示例性半導體封裝結構的多電容器結構500b的截面圖。需要說明的是,多電容器結構500b可以包括與圖5A所示的多電容器結構500a相同或相似的部件,為簡單起見,不再贅述。
在一些實施例中,電容器510和電容器520面對面(face to face)堆疊,如圖5B所示。亦即,電容器520的有源表面510a靠近(朝向)電容器520的有源表面520a。如圖5B所示,多電容器結構500b可以包括在電容器520的背側表面520b上的複數個端子504。端子504可以設置在正面重分佈層302(如圖3所示)和電容器520之間,並且可以將正面重分佈層302電耦接到電容器520。上述圖5A及5B的實施例中,透過形成堆疊的電容器結構來增加電容值,同時堆疊的電容器結構將節省平面的空間,上述方式不會增加對平面面積的佔用,節省了平面空間的佔用。

此外,在一些實施例中,至少一個電容器設置在模制材料上。與晶粒側電容器相比,根據本發明這些實施例的電容器可以降低製造的複雜性和成本。還可以提高半導體封裝結構的可靠性。
儘管已經對本發明實施例及其優點進行了詳細說明,但應當理解的是,在不脫離本發明的精神以及申請專利範圍所定義的範圍內,可以對本發明進行各種改變、替換和變更。所描述的實施例在所有方面僅用於說明的目的而並非用於限制本發明。本發明的保護範圍當視所附的申請專利範圍所界定者為准。本領域技術人員皆在不脫離本發明之精神以及範圍內做些許更動與潤飾。
