Description
本發明涉及半導體技術領域,尤其涉及一種半導體封裝組件。
封裝上封裝(Package-on-package,PoP)封裝組件是一種積體電路封裝方法,用於組合垂直分立的系統單晶片(system-on-chip,SOC)和記憶體封裝。兩個或複數個封裝相互疊置安裝,即堆疊,具有標準介面(standard interface)以在它們之間路由訊號。這允許在行動電話、個人數位助理(personal digital assistant,PDA)和數碼相機等設備中實現更高的部件密度(component density)。
高頻帶封裝疊層封裝(High band package on package,HBPOP)通常用作高端智慧手機SOC的封裝候選,並且具有高頻寬和訊號傳輸路徑短的優點。然而,HBPOP仍然面臨著散熱和封裝高度收縮(shrinkage)的挑戰。
因此,需要一種新穎的半導體封裝組件。
有鑑於此,本發明提供一種半導體封裝組件,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組件,包括:系統單晶片封裝,包括:邏輯晶粒,具有焊盤;以及第一基板,透過該焊盤電連接到該邏輯晶粒;

根據本發明的第二方面,公開一種半導體封裝組件,包括:系統單晶片封裝,包括:邏輯晶粒,其中該邏輯晶粒的背表面從該系統單晶片封裝的上表面暴露;以及第一基板,電連接到該邏輯晶粒;記憶體封裝,堆疊在該系統單晶片封裝上,包括:第二基板,具有上表面和底表面;以及記憶體晶粒,安裝在該第二基板的該上表面上並使用接合引線電連接到該第二基板;以及散熱器,與該第二基板的該底表面部分重疊,與該邏輯晶粒的背表面接觸。
根據本發明的第三方面,公開一種半導體封裝組件,包括:系統單晶片封裝,包括:邏輯晶片;以及第一基板,電連接到該邏輯晶粒;記憶體封裝,堆疊在該系統單晶片封裝上,該記憶體封裝與該系統單晶片封裝之間無間隙,該記憶體封裝包括:第二基板,具有上表面和底表面;以及記憶體晶粒,安裝在該第二基板的該上表面上並使用接合引線電連接到該第二基板;以及散熱器,位於該系統單晶片封裝和該記憶體封裝之間,並與該邏輯晶粒接觸。
本發明的半導體封裝組件由於包括:系統單晶片封裝,包括:邏輯晶粒,具有焊盤;以及第一基板,透過該焊盤電連接到該邏輯晶粒;記憶體封裝,堆疊在該系統單晶片封裝上,包括:第二基板,具有上表面和底表面;以及記憶體晶粒,安裝在該第二基板的該上表面上並使用接合引線電連接到該
第二基板;以及散熱器,位於該系統單晶片封裝和該記憶體封裝之間,其中該散熱器與遠離該焊盤的該邏輯晶粒的背表面接觸。本發明採用套筒式的散熱器將記憶體封裝的四周全部圍繞,使得熱量可以從記憶體封裝四周散發,大幅提高了散熱的面積,從而大大提高了散熱效率。

表面325的SOC封裝300a的平行邊緣(未示出)設置為陣列。。因此,邏輯晶粒302設置在導電結構314a之間。在一些實施例中,導電結構314a可以包括諸如銅球的導電球結構、諸如銅凸塊或焊料凸塊結構的導電凸塊結構、或諸如銅柱結構的導電柱結構。
如圖1所示,SOC封裝300a還包括電子元件330,該電子元件330安裝在與邏輯晶粒302相對的基板316的表面326上。在一些實施例中,電子元件330在其上具有焊盤332並且焊盤332電連接到基板316的導電跡線318(雖然圖中未直接示出)。在一些實施例中,電子元件330佈置在導電結構322之間。電子元件330可以不被模塑料覆蓋。在一些實施例中,電子元件330包括集成無源裝置(integrated passive device,IPD),其包括電容器、電感器、電阻器或其組合。在一些實施例中,電子元件330包括DRAM晶粒。因此電子元件330可以是有源裝置或無源裝置。
如圖1所示,記憶體封裝400a透過接合製程堆疊在SOC封裝300a上。在一些實施例中,記憶體封裝400a包括動態隨機存取記憶體(dynamic random access memory,DRAM)封裝或另一適用的記憶體封裝。在一些實施例中,記憶體封裝400a包括基板418和至少一個記憶體晶粒,至少一個記憶體晶粒例如包括堆疊在基板418上的兩個記憶體晶粒402和404。在一些實施例中,記憶體晶粒402包括動態隨機存取記憶體(DRAM)晶片或其他適用的記憶體晶片。基板418具有上表面420和底表面422。例如,上表面420可以用作晶粒附接表面420,而底表面422可以用作與晶粒相對的凸塊附接(bump-attach)表面422。在這個實施例中,如圖1所示,有兩個記憶體晶粒402和404安裝在基板418的上表面(晶粒連接表面)420上。記憶體晶粒404使用膏劑(paste)(未示出)堆疊在記憶體晶粒402上,並且記憶體晶粒402透過膏劑(未示出)安裝在基板418的晶粒附接表面420上。記憶體晶粒402和404可以使用接合引線414和416電連接到基板418,例如接
合引線414連接記憶體晶粒402的焊盤408與基板418的焊盤424,接合引線416連接記憶體晶粒404的焊盤410與基板418的焊盤426。然而,堆疊的記憶體晶粒的數量不限於本實施例所公開的。或者,如圖1所示的記憶體晶粒402和404可以並排佈置。因此,記憶體晶粒402和404透過膏劑安裝在基板418的上表面(晶粒附接表面)420上。
如圖1所示,基板418可以包括電路428和金屬焊盤(焊盤)424、426和430。金屬焊盤424和426設置在電路428的頂部,靠近頂部表面(晶粒附接表面)420。金屬焊盤(焊盤)430設置在電路428的底部,靠近基板418的底表面(凸塊連接表面)422。記憶體封裝400a的電路428透過設置在基板418的底表面(凸塊附接表面)422上的導電結構432互連到基板316的導電跡線318。在一些實施例中,記憶體封裝400a透過導電結構314穿過記憶體封裝400a和SOC封裝300a的基板316之間的模塑料312而電耦接到基板316的導電跡線318。此外,導電結構432透過SOC封裝300a的焊盤315電連接至導電結構314a。在一些實施例中,導電結構432可以包括導電凸塊結構,例如銅凸塊或焊料凸塊結構、導電柱結構或導電膏結構。
在一些實施例中,如圖1所示,記憶體封裝400a還包括模制材料(或模塑料)412,其覆蓋基板418的上表面420,包封(encapsulating)記憶體晶粒402和404以及接合引線414和416。模制材料(或模塑料)312和412可以包括相同或相似的材料和製造製程。
如圖1所示,半導體封裝組件500a還包括底部填充物450,其填充SOC封裝300a和記憶體封裝400a之間的間隙,使得記憶體封裝400a可以堆疊在SOC封裝300a上而它們之間沒有間隙。記憶體封裝400a的導電結構432被底部填充物450包圍。在一些實施例中,如圖1所示,底部填充物450與導電結構432和記憶體封裝400a的基板418的底表面422(也用作記憶體封裝400a的底表面)、SOC
封裝300a的上表面324接觸。因此,SOC封裝300a的模塑料312透過底部填充物450與記憶體封裝400a的基板418分離(或分隔開)。在一些實施例中,底部填充物450包括毛細管底部填充物(capillary underfill,CUF)、模制底部填充物(molded underfill,MUF)或它們的組合。
如圖1所示,散熱器600a設置在SOC封裝300a和記憶體封裝400a之間。在一些實施例中,散熱器600a與底部填充物450和邏輯晶粒302相鄰並接觸。此外,散熱器600a與遠離焊盤304的邏輯晶粒302的背表面303接觸。在一個實施例中,散熱器600a可以與邏輯晶粒302的背表面303直接接觸,以直接的接觸高效散熱。在另一個實施例中,散熱器600a可以與邏輯晶粒302的背表面303未接觸,例如兩者之間設有散熱材料或者設有底部填充物450,這樣也可以高效散熱,並且更加方便生產製造。此外,散熱器600a完全覆蓋邏輯晶粒302的背表面303。如圖1和2A-2C所示,散熱器600a環繞(或包裹)在記憶體封裝400a周圍並且覆蓋整個記憶體晶粒402和404。參考圖1和2A-2C,散熱器600a覆蓋記憶體封裝400a的上表面413和側表面415的部分並且部分重疊記憶體封裝400a的基板418的底表面422。如圖1和2A-2C所示,散熱器600a形成為不覆蓋靠近和/或被導電結構432覆蓋的基板418的底表面422的一部分。在一個實施例中,散熱器600a包括覆蓋記憶體封裝400a的上表面413的頂部部分、覆蓋基板418的底表面422的底部部分和覆蓋記憶體封裝400a兩個側面的兩個側面部分,圖1中顯示的是其中的一個側面部分,底部部分可以與邏輯晶粒302的背表面303直接接觸或未直接接觸。如圖1和2A-2C所示,SOC封裝300a的導電結構314a和記憶體封裝400a的導電結構432與散熱器600a分離(或分隔開)。因此,可以避免導電結構432和/或導電結構314a與散熱器600a之間的短路。在一些實施例中,散熱器600a包括導電材料,例如包括銅、金、銀或其他適用金屬的金屬。例如,散熱器600a可以包括銅箔。在一些實施例中,半導體封裝組件500a還包括粘合劑602以將散熱器
600a(例如,銅箔)粘附到記憶體封裝400a。粘合劑602設置在散熱器600a和記憶體封裝400a之間。在一些實施例中,粘合劑602包括導電銀漿(膏)、丙烯酸粘合劑、導電陶瓷粘合劑或其他適用的粘合劑。本發明實施例中,採用套筒式的散熱器600a將記憶體封裝400a的四周全部圍繞,使得熱量可以從記憶體封裝400a四周散發,大幅提高了散熱的面積,從而大大提高了散熱效率。本發明實施例中,散熱器600a的頂部部分可以全部或部分覆蓋記憶體封裝400a的上表面413,散熱器600a的底部部分可以全部或部分覆蓋基板418的底表面422,散熱器600a的側面部分可以全部或部分覆蓋記憶體封裝400a的側面(圖1中前側面和後側面)。此外,散熱器600a還可以具有覆蓋記憶體封裝400a其餘兩個側面(圖1中左右兩端未示出的側面(其中一個為側面415))的部分,並且也可以是設計為全部或部分覆蓋這些側面。另外,本實施例中也可以對SOC封裝300a採用與散熱器600a相類似的設計,也即採用套筒式的散熱器安裝在SOC封裝300a上,以圍繞SOC封裝300a的四周(或五個面、六個面)。本實施例中可以針對記憶體封裝400a和SOC封裝300a中的至少一個設置套筒式的散熱器,每個套筒式的散熱器的每個覆蓋面都可以各自自由的設置為全部或部分覆蓋所對應的封裝的側面(上下左右前後面中的至少四個側面)。本發明另一個實施例中,套筒式的散熱器可以將記憶體封裝400a和SOC封裝300a同時圍繞,也即用一個散熱器圍繞記憶體封裝400a和SOC封裝300a,以高效散熱,並且提高封裝結構的穩定性。本發明實施例中,套筒式的散熱器600a的特點在於,散熱器600a為連續的結構並且連續的覆蓋半導體封裝(記憶體封裝400a或/和SOC封裝300a)的至少四個側面(上表面(頂表面)、下表面(底表面)、左側面、右側面、前表面、後表面中的至少四個側面)。散熱器600a可以是一體的結構,以提高半導體封裝組件的機械強度,並提高散熱效率。
圖3是根據本發明的一些實施例的半導體封裝組件500b的橫截
面。圖4A是示出根據本發明的一些實施例的圖3所示的半導體封裝組件500b的散熱器600b和記憶體封裝400a的佈置的俯視圖。圖4B是顯示根據本發明的一些實施例的圖3所示的半導體封裝組件500b的散熱器600b和記憶體封裝400a的佈置的側視圖。圖4C是顯示根據本發明的一些實施例的圖3所示的半導體封裝組件500b的散熱器600b和記憶體封裝400a的佈置的仰視圖。為簡潔起見,下文實施例的與先前參照圖1和2A-2C描述的那些相同或相似的元件不再重複。
半導體封裝組件500a和半導體封裝組件500b之間的區別在於,半導體封裝組件500b包括環繞(或包裹)記憶體封裝400a並完全覆蓋記憶體封裝400a的頂表面413和側表面415的散熱器600b,也即散熱器600b覆蓋記憶體封裝400a的所有的六個面(上表面(頂表面)、下表面(底表面)、左側面、右側面、前表面、後表面)。在一些實施例中,散熱器600b透過諸如濺射製程的塗覆製程形成。因此,散熱器600b可以共形地(conformally)形成,覆蓋整個上表面413和整個側面415以及基板418的一部分底表面422。如圖3和4A-4C所示,散熱器600b形成為不覆蓋靠近和/或被導電結構432覆蓋的基板418的底表面422的剩餘部分。因此,導電結構432和/或導電結構314a與散熱器600b分開以避免導電結構432和/或導電結構314a與散熱器600b之間的短路。此外,散熱器600b可以形成為與模塑料412和記憶體封裝400a的基板418接觸。在一些實施例中,散熱器600a和600b可以由相同或相似的材料形成。在一些實施例中,散熱器600b的厚度可以比散熱器600a的厚度薄。
圖5是根據本發明的一些實施例的半導體封裝組件500c的橫截面。圖6A是示出根據本發明的一些實施例的圖5所示的半導體封裝組件500c的散熱器600c和系統單晶片(SOC)封裝300a的佈置的俯視圖。圖6B是顯示根據本發明的一些實施例的圖5所示的半導體封裝組件500c的散熱器600c和系統單晶片(SOC)封裝300a的佈置的側視圖。為簡潔起見,以下實施例的與先前參照圖1、
2A-2C、3和4A-4C描述的那些相同或相似的元件不再重複。
半導體封裝組件500a和半導體封裝組件500c之間的區別在於半導體封裝組件500c包括環繞(或包裹)SOC封裝300a的散熱器600c。在一些實施例中,散熱器600c設置在底部填充物450和SOC封裝300a的邏輯晶粒302的背表面303之間。此外,散熱器600c環繞(或包裹)在SOC封裝300a的側表面325周圍並且部分覆蓋SOC封裝300a的上表面324。與圖1中散熱器600a圍繞記憶體封裝400a的方式相類似,散熱器600c也是以套筒式的方式安裝在SOC封裝300a上,散熱器600c圍繞SOC封裝300a的方式可以與散熱器600a圍繞記憶體封裝400a的方式相似,可以參考上面對散熱器600a的描述,在此不再贅述。
在一些實施例中,散熱器600c透過諸如濺射製程的塗覆製程形成。因此,散熱器600c可以共形地形成,覆蓋SOC封裝300a的上表面324的一部分和側面(側表面)325的一部分。在一些實施例中,如圖5、6A和6B所示,散熱器600c形成為不覆蓋SOC封裝300a的頂表面(上表面)324的與導電結構314a重疊的剩餘部分。導電結構314a和/或導電結構432與散熱器600c分開以避免導電結構314a和/或導電結構432與散熱器600c之間的短路。此外,散熱器600c可以形成為與SOC封裝300a的模塑料312接觸。此外,散熱器600c可以形成為不覆蓋SOC封裝300a的基板316的側表面(側表面325的一部分)和底表面326,因為邏輯晶粒302產生的熱量主要傳遞到記憶體封裝400a的上層。在一些實施例中,散熱器600a、600b和600c可以由相同或相似的材料形成。在一些實施例中,散熱器600c的厚度可以比散熱器600a的厚度薄,並且散熱器600c的厚度可以與散熱器600b的厚度相同。
在一些實施例中,半導體封裝組件500a、500b和500c使用填充在上部記憶體封裝400a和下部SOC封裝300a之間的間隙的底部填充物450來降低從SOC封裝300a到記憶體封裝400a的熱阻。此外,記憶體封裝400a和SOC封裝300a
可以具有靠近封裝邊緣的合適引腳分配。因此,可以在沒有為SOC封裝300a和記憶體封裝400a之間的電連接提供中介層的情況下製造SOC封裝300a。因此,可以進一步降低半導體封裝組件500a、500b和500c的高度。在一些實施例中,半導體封裝組件500a、500b和500c還包括設置在記憶體封裝400a的底表面422和SOC封裝300a的上表面324之間的散熱器600a、600b和600c。散熱器600a、600b和600c與邏輯晶粒302的背表面303接觸,從而提供了附加的散熱路徑,除了原來的散熱路徑(例如,從下SOC封裝300a到上記憶體封裝400a的導電路徑)外,還直接將來自SOC封裝300a的熱量散發到外部環境。因此,可以進一步提高半導體封裝組件500a、500b和500c的散熱能力。
圖7是根據本發明的一些實施例的半導體封裝組件500d的橫截面。為簡潔起見,下文實施例的與先前參照圖1、2A-2C、3、4A-4C、5、6A和6B描述的那些相同或相似的元件(或部件、組件)不再重複。
在一些實施例中,半導體封裝組件500d是三維(3D)封裝中封裝(PIP)半導體封裝組件。半導體封裝組件500b可以包括安裝在基座200上的至少兩個垂直堆疊的晶片級半導體封裝。如圖7所示,在一些實施例中,半導體封裝組件500d包括系統單晶片(SOC)封裝300b,記憶體封裝400b垂直堆疊在SOC封裝300b上。
如圖7所示,SOC封裝300b透過接合製程安裝在基底200的晶粒附接表面202上。SOC封裝300a和SOC封裝300b之間的區別之一在於SOC封裝300b包括設置在基板316的表面327上的導電結構314b,其中邏輯晶粒302設置在基板316上並且電連接到基板316。在一些實施例中,導電結構314b包括單一結構或複合結構。例如,導電結構314b可以包括與導電結構314a相同或相似的單個結構。例如,導電結構314b可以包括複合結構,該複合結構包括彼此連接的導電結構314b1和導電結構314b2。在一些實施例中,導電結構314b1包括與導電結構
314a相同或相似的結構。在一些實施例中,導電結構314b2包括預焊(pre-solder)結構。
SOC封裝300a和SOC封裝300b之間的另一個區別在於,圍繞邏輯晶粒302的SOC封裝300b的模塑料312與背表面303(邏輯晶粒302的背表面303)和邏輯晶粒302接觸。此外,模塑料化合物(模塑料)312覆蓋邏輯晶粒302的整個背表面303。模塑料312覆蓋邏輯晶粒302的背表面303,使得邏輯晶粒302的背表面303未從模塑料312露出。
在一些實施例中,在製造SOC封裝300b時沒有阻焊層313和焊盤315覆蓋與基板316相對的模塑料312的上表面。因此,模塑料312的上表面可以用作SOC封裝300b的上表面324。導電結構314b穿過模塑料312並從模塑料312的上表面暴露出遠離基板316(即,SOC封裝300b的上表面324)。
如圖7所示,記憶體封裝400b透過接合製程堆疊在SOC封裝300b上。記憶體封裝400a和記憶體封裝400b之間的區別之一在於記憶體封裝400b在製造時沒有如圖1所示的導電結構432。在一些實施例中,記憶體封裝400b堆疊在SOC封裝300b上,它們之間沒有間隙。也即基板418的底表面422與SOC封裝300b的上表面324直接接觸,因此相較於圖1的實施例,圖7的實施例中無需設置底部填充物450,從而可以更高效的散熱(例如無需設置散熱器600a也可以高效散熱)。此外,底部記憶體封裝400b的基板418的表面422可以與SOC封裝300b的上表面324接觸,而在它們之間沒有間隙。如圖7所示,靠近記憶體封裝400b的基板418的底表面422的金屬焊盤430可以與SOC封裝300b的對應導電結構314b接觸。在一些實施例中,模塑料312與記憶體封裝400b的基板418的底表面422接觸。
在一些實施例中,半導體封裝組件500d被設計成將記憶體封裝400b堆疊在SOC封裝300b上,以使記憶體封裝400b的基板418的底表面422與SOC
封裝300b的導電結構314b接觸而在它們之間不存在間隙的方式。因此,可以降低從SOC封裝300b到記憶體封裝400b的熱阻。此外,可以進一步提高半導體封裝組件500d的散熱能力。此外,記憶體封裝400b和SOC封裝300b可以具有靠近封裝邊緣的合適引腳分配。因此,SOC封裝300b可以在沒有中介層、阻焊層和靠近上表面324的對應焊盤的情況下製造,以提供SOC封裝300b和記憶體封裝400b之間的電連接。此外,記憶體封裝400b可以在記憶體封裝400b的底表面422和SOC封裝300b的上表面324之間沒有導電結構(例如圖1所示的導電結構432)的情況下製造。因此,可以進一步降低半導體封裝組件500d的高度。
