第一半導體晶片300的第一組的晶片焊墊310可均勻地設置在第一半導體晶片300的第一表面301的整個區域上,如圖3所示。第二半導體晶片400的第二組的晶片焊墊410可設置在第二半導體晶片400的突出部435上。第二半導體晶片400的第二組的晶片焊墊410可設置在第二半導體晶片400的相對於第一半導體晶片300外伸(不交疊)的部分(即,突出部435)上。第二半導體晶片400的第二組的晶片焊墊410可設置在第二半導體晶片400的外圍區域430上。設置有第二組的晶片焊墊410的外圍區域430可位於第二半導體晶片400的突出部435的第一表面401上。
第二半導體晶片400可與第一半導體晶片300部分地交疊。第二半導體晶片400的除了突出部435之外的其它區域可與第一半導體晶片300交疊。第二半導體晶片400的所述其它區域可由第一半導體晶片300共享。因此,第二半導體晶片400的第二組的晶片焊墊410可能不設置在第二半導體晶片400的所述其它區域上。
第一晶片焊墊312可通過第一電路徑P1電連接到第二晶片焊墊412。第一晶片焊墊312可以是第一組的晶片焊墊310中的一個。儘管圖3將第一電路徑P1示出為單個路徑,但SiP 10可包括多個第一電路徑P1。在這種情況下,第一組的晶片焊墊310可分別通過多個第一電路徑P1電連接到第二組的晶片焊墊410。在實施方式中,多個第一電路徑P1中的每一個可被配置為包括第二半導體晶片400的第二組的晶片焊墊410中的一個、第三組的內連接器630中的一個、柱狀凸塊530中的一個、通孔520中的一個、通孔焊墊540中的一個、第二組的內連接器620中的一個、第一RDL圖案120中的一個、第一組的內連接器610中的一個以及第一半導體晶片300的第一組的晶片焊墊310中的一個。由於第二半導體晶片400通過多個第一電路徑P1電連接到第一半導體晶片300,所以可在第一半導體晶片300和第二半導體晶片400之間提供多個輸入/輸出(I/O)路徑。即,由於兩個相鄰的半導體晶片通過與I/O路徑對應的多個短信號路徑彼此電連接,所以與通過單個路徑相比,可通過多個路徑在兩個相鄰的半導體晶片之間同時發送相對更多的數據。因此,可使用平行路徑以給定速度從第一半導體晶片300向第二半導體晶片400發送更大量的數據,或者反之亦然。如果第一半導體晶片300是處理器晶片並且第二半導體晶片400是記憶體晶片,則第一半導體晶片300可與充當高性能快取記憶體的第二半導體晶片400一起操作。因此,可改進包括第一半導體晶片300和第二半導體晶片400的SiP 10的操作速度和性能。

儘管圖中未示出,第二子封裝件SP2可被設置為包括:半導體晶粒,其包括整合電路;內部互連線,其用於半導體晶粒中的組件之間的電連接;以及模製層,其保護半導體晶粒。
第四電路徑P4可被設置為包括第一互連器257、第二柱狀凸塊537、第二通孔527、第八內連接器627、第二RDL圖案170、第四內連接器617和第五晶片焊墊317。第四電路徑P4可充當將第二子封裝件SP2電連接到第一半導體晶片300的電路徑。

第二互連器258、第四柱狀凸塊538、第四通孔528、第四通孔焊墊548、第七RDL圖案180、第八RDL圖案190和第三外連接器270可構成第五電路徑P5。第五電路徑P5可以是將電源電壓或接地電壓供應給第二子封裝件SP2的電路徑。
圖5是示出圖1的一部分(包括第一橋接晶粒501和第二橋接晶粒505)的放大橫截面圖。這裡,由於兩個橋接晶粒505在結構上相似,所以給予圖1的最右橋接晶粒505及其組件與圖1的最左橋接晶粒505及其組件相同的標號。圖6是示出圖5所示的第一橋接晶粒501和第二橋接晶粒505的柱狀凸塊530和535的平面圖。
參照圖1和圖5,第一橋接晶粒501的第一主體510可對應於諸如矽基板的半導體基板。第二橋接晶粒505的第二主體515也可對應於半導體基板(例如,矽基板)。由於第一橋接晶粒501的第一主體510和第二橋接晶粒505的第二主體515包括矽材料,所以可使用應用於矽晶圓的光學微影製程來形成通孔520和525。
第一橋接晶粒501的通孔520可對應於具有直徑D1的矽通孔(TSV)。直徑D1可小於穿透模製層的模製通孔(TMV)的直徑。因此,可增加在具有有限尺寸的第一主體510中形成的通孔520的數量。第二橋接晶粒505的通孔525也可形成為具有直徑D11的TSV。
如圖3所示,第二組的晶片焊墊410可密集地設置在第二半導體晶片400的突出部435上。第一橋接晶粒501的電連接到第二組的晶片焊墊410的柱狀凸塊530可包括至少兩個凸塊,如圖6所示。在這種情況下,第一橋接晶粒501的通孔520可對準以與第二組的晶片焊墊410交疊,使得第一橋接晶粒501的柱狀凸塊530與第二半導體晶片400的第二組的晶片焊墊410交疊。由於使用TSV工藝形成第一橋接晶粒501的通孔520,所以例如與TMV的直徑相比,通孔520可形成為具有值相對小的直徑D1。因此,可使第一橋接晶粒501的分別與多個I/O端子、電源端子和接地端子對應的通孔520的數量最大化。即,即使第二組的晶片焊墊410密集地設置,也可形成第一橋接晶粒501的通孔520,使得通孔520被設置為具有與第二組的晶片焊墊410相同的間距大小。因此,即使第二組的晶片焊墊410密集地設置,也可將第二組的晶片焊墊410垂直地連接到第一橋接晶粒501的相應通孔520,而不在第二半導體晶片400上形成任何再分配線。
如果第一橋接晶粒501的通孔520的直徑D1減小,則通孔520的垂直長度也可減小。當第一橋接晶粒501的通孔520形成為穿透具有厚度T3的第一主體510時,由於由通孔520填充的過孔的縱橫比的限制,在減小通孔520的直徑D1方面可存在限制。為了減小第一橋接晶粒501的通孔520的直徑D1,可能有必要減小第一主體510的厚度T3以滿足形成通孔520的通孔洞的縱橫比的限制。為了增加第一主體510中形成的通孔520的數量,可能有必要將第一主體510的厚度T3減小為小於第一半導體晶片300的厚度T1。在這種情況下,可減小第一橋接晶粒501的通孔520的直徑D1。
第一橋接晶粒501的第一主體510的厚度T3可小於第二橋接晶粒505的第二主體515的厚度T33。第一橋接晶粒501的第一通孔522的直徑D1可小於第二橋接晶粒505的第二通孔527的直徑D11。由於第二橋接晶粒505的第二主體515比第一橋接晶粒501的第一主體510厚,所以在由於縱橫比的限制第二通孔527的直徑D11大於第一通孔522的直徑D1的情況下,第二通孔527可基本上充分地穿透第二主體515。
第二柱狀凸塊537的直徑D22可大於第二通孔527的直徑D11。第二通孔焊墊547的直徑D33可大於第二通孔527的直徑D11。第二柱狀凸塊537的直徑D22也可大於第一柱狀凸塊532的直徑D2。因此,如圖6所示,柱狀凸塊535的間距大小S2可大於柱狀凸塊530的間距大小S1。
參照圖5,為了第一橋接晶粒501在結構上支撐第二半導體晶片400,第一橋接晶粒501的總厚度T2被設定為等於第一半導體晶片300的厚度T1可能是有效的。例如,小於第一半導體晶片300的厚度T1的第一主體510的厚度T3可由第一橋接晶粒501的柱狀凸塊530的厚度T4和第一橋接晶粒501的通孔焊墊540的厚度T5補償。即,通過適當地調節第一橋接晶粒501的柱狀凸塊530的厚度T4,第一橋接晶粒501的總厚度T2可被調節為等於第一半導體晶片300的厚度T1。第一橋接晶粒501的總厚度T2可包括第一橋接晶粒501的柱狀凸塊530的厚度T4、第一橋接晶粒501的通孔焊墊540的厚度T5和第一主體510的厚度T3。
第一橋接晶粒501的柱狀凸塊530可分別直接接合到第三組的內連接器630。第一柱狀凸塊532的直徑D2可大於第一橋接晶粒501的通孔520的直徑D1。因此,用作第三組的內連接器630的焊料凸塊可分別直接接合到第一橋接晶粒501的柱狀凸塊530。為了第一橋接晶粒501的通孔焊墊540直接接合到第二組的內連接器620,通孔焊墊540的直徑D3可大於第一橋接晶粒501的通孔520的直徑D1。
圖7是示出圖1所示的第一半導體晶片300和第二半導體晶片400之間的連接部分的放大橫截面圖。
參照圖1和圖7,第二半導體晶片400可與第一半導體晶片300部分地交疊,並且第二半導體晶片400的突出部435可由第一橋接晶粒501支撐。第二半導體晶片400的突出部435通過第三組的內連接器630接合到第一橋接晶粒501,並且虛擬凸塊690可用於支撐第二半導體晶片400的與突出部435相對的邊緣436。由於虛擬凸塊690支撐第二半導體晶片400的邊緣436,所以可防止第二半導體晶片400傾斜。由於當第二半導體晶片400的突出部435接合到第一橋接晶粒501時虛擬凸塊690設置在第一半導體晶片300與第二半導體晶片400之間,所以第二半導體晶片400可維持水平高度。
虛擬凸塊690可以是焊料凸塊。虛擬凸塊690可附接到第二半導體晶片400的第一表面401。虛擬接合焊墊691可形成在第二半導體晶片400的第一表面401上。在這種情況下,虛擬凸塊690可接合到虛擬接合焊墊691。虛擬接合焊墊691可形成在設置在第二半導體晶片400的第一表面401上的鈍化層425上。虛擬接合焊墊691可使用金屬濺鍍製程形成在鈍化層425上。鈍化層425可形成為覆蓋第二半導體晶片400的主體420(由矽材料製成)並將其電絕緣。因此,虛擬凸塊690可與第二半導體晶片400的內部電路電絕緣。虛擬凸塊690可與第一半導體晶片300的與RDL結構100相對的第二表面302接觸。
圖8是示出根據另一實施方式的SiP 11的橫截面圖。
參照圖8,SiP 11可被實現為具有層疊封裝(PoP)形狀。SiP 11可被配置為包括第一子封裝件SP1’以及安裝在第一子封裝件SP1’上的第二子封裝件SP2。第一子封裝件SP1’可被配置為包括RDL結構100、第一半導體晶片300、第二半導體晶片400、第一橋接晶粒501、第二橋接晶粒505和模製層700。第二半導體晶片400可與第一半導體晶片300部分地交疊,並且第二半導體晶片400的突出部435可由第一橋接晶粒501在結構上支撐。黏合層690L可設置在第一半導體晶片300與第二半導體晶片400之間。黏合層690L可支撐第二半導體晶片400。當第二半導體晶片400的突出部435接合到第一橋接晶粒501並由第一橋接晶粒501支撐時,黏合層690L可防止第二半導體晶片400傾斜。黏合層690L可幫助第二半導體晶片400維持水平高度。
黏合層690L可附接到第二半導體晶片400的第一表面401和第一半導體晶片300的第二表面302。黏合層690L可將第二半導體晶片400接合到第一半導體晶片300。

再參照圖9,第一橋接晶粒501-1的第一模製材料基板510-1可由模製材料或囊封材料形成。第二橋接晶粒505-1的第二模製材料基板515-1可由模製材料或囊封材料形成。第一模製材料基板510-1和第二模製材料基板515-1可包括兩種不同的材料。第一模製材料基板510-1和第二模製材料基板515-1可由不同於模製層700的材料形成。例如,第一模製材料基板510-1和第二模製材料基板515-1可由組分不同於模製層700的環氧樹脂模製料(EMC)材料的組分的EMC材料形成。

如上所述,根據一些實施方式,第二半導體晶片400可層疊在第一半導體晶片300上以減小SiP 10、11或12的寬度或大小。根據SiP 10、11或12,由於第二半導體晶片400使用第一橋接晶粒501或501-1電連接到第一半導體晶片300,所以可在第一半導體晶片300上層疊第二半導體晶片400。
對半導體晶片施加熱的製程可使半導體晶片(具體地,記憶體晶片)的特性劣化。例如,當熱施加到DRAM裝置時,DRAM裝置的記憶體單元的數據保持時間減少,從而減小DRAM裝置的刷新循環時間。另外,如果熱施加到NAND型快閃裝置,則NAND型快閃裝置的記憶體單元的數據保持時間也可減小。
根據本教導的實施方式的SiP 10、11和12可被實現為包括內連接器,內連接器附接到RDL結構100以用於半導體晶片之間以及外部裝置與半導體晶片之間的互連。因此,可省略或減少使用於形成再分配線的聚合物層固化的熱製程(或退火製程)。結果,SiP 10、11和12的性能可改進。例如,如果在形成RDL結構100之後第一半導體晶片300和第二半導體晶片400層疊在RDL結構100上以形成SiP 10、11或12,則當執行熱製程(或退火製程)以使用於形成RDL圖案的聚合物層固化時,可防止熱施加到第一半導體晶片300和第二半導體晶片400。

電子系統8710還可包括被配置為向通信網絡發送數據以及從通信網絡接收數據的介面8714。介面8714可為有線或無線型。例如,介面8714可包括天線或者有線或無線收發器。
