Abstract

本發明概念提供一種包括中介層的半導體封裝。半導體封裝包括：封裝基礎基板；下部重佈線結構，設置於封裝基礎基板上且包括多個下部重佈線圖案；至少一個中介層，包括多個第一連接柱及多個連接配線圖案，所述多個第一連接柱在下部重佈線結構上彼此間隔開且分別連接至所述多個下部重佈線圖案的一些部分；上部重佈線結構，在所述多個第一連接柱及所述至少一個中介層上包括多個上部重佈線圖案，所述多個上部重佈線圖案分別連接至所述多個第一連接柱及所述多個連接配線圖案；以及至少兩個半導體晶片，黏合於上部重佈線結構上，同時彼此間隔開。

Description

包括中介層的半導體封裝
本發明概念是有關於一種包括多個半導體晶片的半導體封裝，且更具體而言，是有關於一種包括用於將所述多個半導體晶片內連至彼此的中介層的半導體封裝。
[相關申請案的交叉參考]
本申請案主張於2018年7月31日在韓國智慧財產局提出申請的韓國專利申請案第10-2018-0089508號的權利，所述韓國專利申請案的全部揭露內容併入本案供參考。
根據電子行業的發展及使用者的需求，電子裝置已進一步微型化、多功能化及/或大容量化，且因此，需要包括多個半導體晶片的半導體封裝。

舉例而言，電源訊號、接地訊號、控制訊號、時脈訊號等自板連接構件270至第一半導體晶片310及第二半導體晶片320中的每一者的傳輸、以及板連接構件270與第一半導體晶片310及第二半導體晶片320中的每一者之間的資料傳輸及/或接收可經由下部重佈線結構210的下部重佈線圖案212及下部通孔圖案214、第一連接柱220、以及上部重佈線結構260的上部重佈線圖案及上部通孔圖案264來執行。另一方面，例如，第一半導體晶片310及第二半導體晶片320之間的資料傳輸及/或接收，以及用於第一半導體晶片310與第二半導體晶片320之間的時脈同步的訊號傳輸可僅經由上部重佈線結構260的上部重佈線圖案262及上部通孔圖案264以及中介層230來執行，而不經過下部重佈線結構210的下部重佈線圖案212及下部通孔圖案214。
根據實施例的半導體封裝1經由能夠達成相對精細的節距的中介層230在所述至少兩個半導體晶片300(例如，第一半導體晶片310及第二半導體晶片320)之間傳輸訊號，且經由以相對低成本製造的第一連接柱220及下部重佈線結構210在板連接構 件270與第一半導體晶片310及第二半導體晶片320中的每一者之間傳輸訊號。
舉例而言，由於對於封裝基礎基板與兩個半導體晶片中的每一者之間的訊號以及所述兩個半導體晶片之間的訊號二者均經由中介層傳輸的半導體封裝而言，所述半導體封裝包括相對大的中介層，因此製造成本可能增加。另一方面，由於對於封裝基礎基板與兩個半導體晶片中的每一者之間的訊號以及所述兩個半導體晶片之間的訊號二者均經由重佈線結構傳輸的半導體封裝而言，半導體封裝不能達成精細節距，因此半導體封裝的大小可能增大或者良率可能降低。
然而，由於半導體封裝1經由中介層230在第一半導體晶片310與第二半導體晶片320之間傳輸訊號，且經由第一連接柱220及下部重佈線結構210在封裝基礎基板100與第一半導體晶片310及第二半導體晶片320中的每一者之間傳輸訊號，因此中介層230的所需大小相對小。因此，半導體封裝1可具有低製造成本及高良率。
圖2至圖8是根據實施例的半導體封裝1a至半導體封裝1g的剖視圖。可省略圖2至圖8的與圖1A及圖1B重複的細節，且主要闡述其不同之處。

根據實施例，連接凸塊225可以與第一連接柱220相似的方式形成於下部重佈線圖案212上。根據另一實施例，連接凸塊225可在製造中介層231的同時形成於位於中介層231的底表面上的貫穿電極238上。根據另一實施例，連接凸塊225可包括在製造中介層231的同時形成於位於中介層231的底表面上的貫穿電極238上的上部部分、以及以與第一連接柱220相似的方式形成於下部重佈線圖案212上的下部部分。
根據實施例的半導體封裝1b可經由中介層231而不藉由下部重佈線結構210在所述至少兩個半導體晶片300之間(例如，在第一半導體晶片310與第二半導體晶片320之間)傳輸訊號，經由第一連接柱220及下部重佈線結構210而不藉由中介層230在板連接構件270與第一半導體晶片310及第二半導體晶片320中的每一者之間傳輸訊號中的一些訊號、以及一起經由中介層 230及下部重佈線結構210在板連接構件270與第一半導體晶片310及第二半導體晶片320中的每一者之間傳輸訊號中的其餘訊號。
舉例而言，在板連接構件270與第一半導體晶片310及第二半導體晶片320中的每一者之間的訊號中，電源訊號、接地訊號及資料的傳輸及接收可經由下部重佈線結構210來執行，而控制訊號及時脈訊號的傳輸及接收可經由中介層230及下部重佈線結構210一起執行。然而，此僅為實例，且因此不受限制。換言之，可慮及第一連接柱220及貫穿電極238的電性特性及水平橫截面來確定板連接構件270與第一半導體晶片310及第二半導體晶片320中的每一者之間的訊號中的每一訊號的路徑。

可將外部連接端子150黏合至封裝基礎基板100的下部接墊124。
接著，如圖2中所示，將熱發射構件500設置成接觸所述至少兩個半導體晶片300的頂表面以形成半導體封裝1a。根據 實施例，半導體封裝1a可藉由將熱發射構件500設置成接觸封裝基礎基板100的頂表面且環繞所述至少兩個半導體晶片300而形成。

第一半導體晶片310a與第二半導體晶片320a可經由半導體封裝2中的上部重佈線結構260及中介層230a電性連接至彼此。
舉例而言，第一半導體晶片310a與第二半導體晶片320a之間的資料傳輸及/或接收以及用於第一半導體晶片310a與第二半導體晶片320a之間的時脈同步的訊號傳輸可僅經由上部重佈線結構260及中介層230a執行。
在根據實施例的半導體封裝2中，由於第一半導體晶片310a與第二半導體晶片320a之間的訊號經由上部重佈線結構260及中介層230a傳輸，而另一訊號不經過中介層230a，因此中介層230a的所需大小相對小。因此，半導體封裝2可具有低的製造成本及高的良率。
圖12是根據實施例的半導體封裝3的平面佈局圖。
參照圖12，半導體封裝3包括：上部重佈線結構260，位於多個中介層230b上；以及多個半導體晶片303，設置於上部重佈線結構260上。所述多個半導體晶片303可設置於上部重佈線結構260上，同時彼此間隔開。所述多個半導體晶片303可包括主半導體晶片310b、第一子半導體晶片320b-I、第二子半導體晶片320b-II、第三子半導體晶片320b-III及第四子半導體晶片320b-IV。

在圖12中，所述多個半導體晶片303包括一個主半導體晶片310b及四個環繞的子半導體晶片(例如，第一子半導體晶 片320b-I至第四子半導體晶片320b-IV)，但作為另一種選擇，所述多個半導體晶片303可包括一個主半導體晶片310b及至少兩個環繞的子半導體晶片。中介層230b的數目可等於或為所述多個半導體晶片303中所包括的子半導體晶片的數目的整數倍。
主半導體晶片310b及第一子半導體晶片320b-I至第四子半導體晶片320b-IV可經由上部重佈線結構260以及第一子中介層230b-I至第四子中介層230b-IV而在半導體封裝3中電性連接至彼此。
在根據實施例的半導體封裝3中，由於主半導體晶片310b與第一子半導體晶片320b-I至第四子半導體晶片320b-IV中的每一者之間的訊號經由上部重佈線結構260及彼此間隔開的第一子中介層230b-I至第四子中介層230b-IV傳輸，而另一訊號不經過所述多個中介層230b，因此所述多個中介層230b的所需大小相對小。因此，半導體封裝3可具有低的製造成本及高的良率。
圖13是根據另一實施例的半導體封裝4的平面佈局圖。
參照圖13，半導體封裝4包括：上部重佈線結構260，位於彼此間隔開的多個中介層230c上；以及多個半導體晶片304，位於上部重佈線結構260上，半導體晶片304包括第一半導體晶片310c至第三半導體晶片330c。所述多個中介層230c可包括第一子中介層230c-I及第二子中介層230c-II。

在半導體封裝4中，第一半導體晶片310c與第二半導體晶片320c可經由上部重佈線結構260及第一子中介層230c-I電性連接至彼此，且第二半導體晶片320c與第三半導體晶片330c可經由上部重佈線結構260及第二子中介層230c-II電性連接至彼此。
在根據實施例的半導體封裝4中，由於第一半導體晶片310c與第二半導體晶片320c之間的訊號以及第二半導體晶片320c與第三半導體晶片330c之間的訊號經由上部重佈線結構260及彼此間隔開的所述多個中介層230c傳輸，而另一訊號不經過所述多個中介層230c，因此所述多個中介層230c的所需大小相對小。因此，半導體封裝4可具有低的製造成本及高的良率。
圖14是根據另一實施例的半導體封裝5的平面佈局圖。
參照圖14，半導體封裝5包括：上部重佈線結構260，位於彼此間隔開的多個中介層230d上；以及至少兩個半導體晶片305，設置於上部重佈線結構260上且包括第一半導體晶片310d及第二半導體晶片320d。所述多個中介層230d可包括第一子中介層230d-I及第二子中介層230d-II。

在半導體封裝5中，第一半導體晶片310d及第二半導體晶片320d可經由上部重佈線結構260及第一子中介層230d-I以及經由上部重佈線結構260及第二子中介層230d-II電性連接至彼此。
在根據實施例的半導體封裝5中，由於第一半導體晶片310d與第二半導體晶片320d之間的訊號經由上部重佈線結構260及所述多個中介層230d傳輸，而另一訊號不經過所述多個中介層230d。另外，由於所述多個中介層230d包括彼此間隔開的第一子中介層230d-I與第二子中介層230d-II，因此所述多個中介層230d的所需大小相對小。另外，由於第一半導體晶片310d與第二半導體晶片320d之間的訊號被分割且經由彼此間隔開的第一子中介層230d-I與第二子中介層230d-II傳輸，因此可增加用於第一半導體晶片310d及第二半導體晶片320d中的每一者的訊號傳輸的晶片接墊(例如，圖1A的第一晶片接墊314及第二晶片接墊324)的設計自由度。因此，半導體封裝5可具有低的製造成本及高的良 率。
