圖1A到圖1K是根據本公開的一些實施例的封裝的製造 流程的示意性剖視圖。參照圖1A,提供半導體晶圓W。在一些實施例中,半導體晶圓W包括晶圓基板WS及形成在半導體晶圓W上的第一內連結構120。在一些實施例中,半導體晶圓W上形成有第一接合結構130,且第一接合結構130也被認為是半導體晶圓W的一部分。
在一些實施例中,晶圓基板WS可由以下半導體製成:合適的元素半導體,例如晶體矽、金剛石或鍺;合適的化合物半導體,例如砷化鎵、碳化矽、砷化銦或磷化銦;或者合適的合金半導體,例如碳化矽鍺、磷化鎵砷或磷化鎵銦。在一些實施例中,晶圓基板WS可包括形成在其中的主動元件(例如電晶體等)和/或被動元件(例如電阻器、電容器、電感器等)。在一些實施例中,晶圓基板WS還可包括穿透晶圓基板WS的多個半導體穿孔(through semiconductor via;TSV),以進行雙面連接(dual-side connection)。然而,在晶圓基板WS中,TSV可為可選的,因此這些TSV未在圖1A中示出。
如圖1A中所示,在晶圓基板WS上設置第一內連結構120。在一些實施例中,第一內連結構120包括第一介電間層(inter-dielectric layer)122、多個第一圖案化導電層124及多個第一導通孔126。在一些實施例中,第一圖案化導電層124及第一導通孔126嵌置在第一介電間層122中。為簡潔起見,第一介電間層122在圖1A中被示出為塊狀層(bulky layer),但是應理解的是,第一介電間層122可由多個介電層構成。第一圖案化導電層 124與第一介電間層122的介電層交替堆疊。在一些實施例中,兩個相鄰的第一圖案化導電層124通過夾置在其之間的導通孔126彼此電性連接。
在一些實施例中,第一介電間層122的材料包括聚醯亞胺、環氧樹脂、丙烯酸樹脂、酚醛樹脂、苯並環丁烯(benzocyclobutene;BCB)、聚苯並噁唑(polybenzoxazole;PBO)、或其他合適的聚合物系介電材料。第一介電間層122例如可通過合適的製作技術(例如旋轉塗布、化學氣相沉積(chemical vapor deposition;CVD)、電漿增強型化學氣相沉積(plasma-enhanced chemical vapor deposition;PECVD)等)形成。在一些實施例中,第一圖案化導電層124及第一導通孔126的材料包括鋁、鈦、銅、鎳、鎢、和/或其合金。第一圖案化導電層124及第一導通孔126可通過例如電鍍、沉積、和/或微影及蝕刻來形成。應注意的是,圖1A中所示的第一圖案化導電層124、第一導通孔126及第一介電間層122中的介電層的數目僅為例示,且本公開並不受限制。在一些替代性實施例中,第一圖案化導電層124的數目、第一導通孔126的數目以及第一介電間層122中的介電層的數目可根據佈線要求進行調整。
在一些實施例中,第一接合結構130包括第一介電層132、多個第一接墊134、多個第一連接件136及多個輔助連接件138。在一些實施例中,第一接墊134形成在第一內連結構120上以使得第一接墊134直接接觸第一內連結構120的最上面的第一 導通孔126。換句話說,第一內連結構120夾置在第一接墊134與晶圓基板WS之間。在一些實施例中,第一接墊134通過最上面的第一導通孔126與第一內連結構120電性連接。在一些實施例中,第一接墊134可為鋁接墊、銅接墊、或其他合適的金屬接墊。應注意的是,第一接墊140的數目及形狀可基於需要進行選擇。在一些實施例中,第一介電層132形成在第一接墊134上以密封第一接墊134。在一些實施例中,第一介電層132的材料包括氧化物,例如氧化矽等。作為另外一種選擇,第一介電層132可包含聚醯亞胺、環氧樹脂、丙烯酸樹脂、酚醛樹脂、苯並環丁烯(BCB)、聚苯並噁唑(PBO)、或任何其他合適的聚合物系介電材料。第一介電層132例如可通過合適的製作技術(例如,旋轉塗布、CVD、PECVD等)形成。
在一些實施例中,第一連接件136及輔助連接件138可通過移除第一介電層132的一部分且將導電材料填充到間隙中來形成。舉例來說,第一連接件136及輔助連接件138可通過雙鑲嵌製程(dual damascene process)形成。因此,每一第一連接件136可包括通孔部分136a及堆疊在通孔部分136a上的溝渠部分136b。類似地,每一輔助連接件138也可包括通孔部分138a及堆疊在通孔部分138a上的溝渠部分138b。在一些實施例中,溝渠部分136b的寬度大於通孔部分136a的寬度。類似地,溝渠部分138b的寬度大於通孔部分138a的寬度。在一些實施例中,第一連接件136及輔助連接件138可由例如鋁、鈦、銅、鎳、鎢、和/或其合 金製成。在一些實施例中,第一連接件136與輔助連接件138同時形成。然而,本公開並不僅限於此。在一些替代性實施例中,第一連接件136與輔助連接件138可分開形成。舉例來說,第一連接件136可在形成輔助連接件138之前或之後形成。如圖1A中所示,第一連接件136設置在第一接墊134上且與第一接墊134直接接觸。在一些實施例中,第一連接件136通過第一接墊134與第一內連結構120電性連接。另一方面,輔助連接件138延伸到第一介電間層122中以直接接觸最上面的第一圖案化導電層124,從而實現與第一內連結構120的電性連接。然而,前述配置僅為例示,且本公開並不僅限於此。在一些替代性實施例中,第一連接件136的配置與輔助連接件138的配置可相同。換句話說,可在輔助連接件138正下方形成其他附加接墊以使得輔助連接件138通過這些附加接墊與第一內連結構120電性連接。如圖1A中所示,第一連接件136及輔助連接件138嵌置在第一介電層132中。
在一些實施例中,半導體晶圓W具有約500μm到約775μm的高度HW。在一些實施例中,第一連接件136的頂表面、輔助連接件138的頂表面及第一介電層132的頂表面可被統稱為半導體晶圓W的主動表面AS1。另一方面,半導體晶圓W的與主動表面AS1相對的表面可被稱為半導體晶圓W的後表面RS1。如圖1A中所示,第一連接件136的頂表面、輔助連接件138的頂表面及第一介電層132的頂表面實質上位於同一水平高度上以提供用 於混合接合(hybrid bonding)的適當的主動表面AS1。
參照圖1B,提供多個半導體晶粒200。在一些實施例中,每一半導體晶粒200包括半導體基板210及形成在半導體基板210上的第二內連結構220。在一些實施例中,每一半導體晶粒200上形成有第二接合結構230,且第二接合結構230也被認為是半導體晶粒200的一部分。在一些實施例中,每一半導體晶粒200更包括形成在其中的多個半導體穿孔(through semiconductor via;TSV)212。舉例來說,TSV 212嵌置在半導體基板210中且與第二內連結構220電性連接。在一些實施例中,每一TSV 212具有約0.9μm到約10μm的寬度W212。另一方面,兩個相鄰的TSV 212具有介於約3μm與約50μm之間的範圍內的節距(pitch)。
在一些實施例中,半導體晶粒200的半導體基板210可類似於半導體晶圓W的晶圓基板WS,因此本文中省略其詳細說明。如圖1B中所示,第二內連結構220設置在半導體基板210上。在一些實施例中,第二內連結構220包括第二介電間層222、多個第二圖案化導電層224及多個第二導通孔226。第二內連結構220的第二介電間層222、第二圖案化導電層224及第二導通孔226可分別類似於第一內連結構120的第一介電間層122、第一圖案化導電層124及第一導通孔126,因此本文中省略其詳細說明。如圖1B中所示,TSV 212直接接觸第二圖案化導電層224中的一者。也就是說,TSV 212通過第二圖案化導電層224中的一者與第二內連結構220電性連接。
在一些實施例中,第二接合結構230包括第二介電層232、多個第二接墊234及多個第二連接件236。第二接合結構230的第二介電層232、第二接墊234及第二連接件236可分別類似於第一接合結構130的第一介電層132、第一接墊134及第一連接件136,因此本文中省略其詳細說明。在一些實施例中,第二連接件236可通過雙鑲嵌製程形成。也就是說,每一第二連接件236可包括通孔部分236a及堆疊在通孔部分236a上的溝渠部分236b。在一些實施例中,溝渠部分236b的寬度大於通孔部分236a的寬度。如圖1B中所示,第二連接件236及第二接墊234嵌置在第二介電層232中。另一方面,第二內連結構220夾置在第二接墊234與半導體基板210之間。
在一些實施例中,每一半導體晶粒200具有約40μm到約200μm的高度H200’。如圖1B中所示,第二連接件236的底表面及第二介電層232的底表面可被統稱為半導體晶粒200的主動表面AS2。另一方面,半導體晶粒200的與主動表面AS2相對的表面可被稱為半導體晶粒200的後表面RS2。如圖1B中所示,第二連接件236的底表面與第二介電層232的底表面實質上位於同一水平高度上以提供用於混合接合的適當的主動表面AS2。
在一些實施例中,半導體晶粒200可為能夠執行儲存功能的晶粒。舉例來說,半導體晶粒200可為動態隨機存取記憶體(Dynamic Random Access Memory;DRAM)、可變電阻式記憶體(Resistive Random Access Memory;RRAM)、靜態隨機存取記憶 體(Static Random Access Memory;SRAM)等。然而,本公開並不僅限於此。在一些替代實施例中,半導體晶粒200可為中央處理器(Central Process Unit;CPU)晶粒、圖形處理單元(Graphic Process Unit;GPU)晶粒、現場可程式化邏輯閘陣列(Field-Programmable Gate Array;FPGA)等。
如圖1B中所示,半導體晶粒200與半導體晶圓W接合。在一些實施例中,半導體晶粒200可通過混合接合製程接合到半導體晶圓W。在一些實施例中,混合接合製程的溫度介於從約150℃到約400℃的範圍內。以下將詳細闡述混合接合製程。
在一些實施例中,可將半導體晶粒200拾取並放置到半導體晶圓W的主動表面AS1上以使得半導體晶粒200與半導體晶圓W電性連接。在一些實施例中,半導體晶粒200被放置成使得半導體晶粒200的主動表面AS2接觸半導體晶圓W的主動表面AS1。同時,半導體晶粒200的第二連接件236實質上對準半導體晶圓W的第一連接件136且直接接觸半導體晶圓W的第一連接件136。舉例來說,每一第一連接件136的溝渠部分136b實質上對準每一第二連接件236的對應的溝渠部分236b且直接接觸每一第二連接件236的對應的溝渠部分236b。
在一些實施例中,為促進半導體晶粒200與半導體晶圓W之間的混合接合,可對半導體晶粒200的接合表面及半導體晶圓W的接合表面(即,主動表面AS1及主動表面AS2)執行表面準備。表面準備可包括例如表面清潔及活化。可對主動表面AS1、 AS2執行表面清潔以移除第一連接件136的接合表面、第二連接件236的接合表面、第一介電層132的接合表面及第二介電層232的接合表面上的顆粒。在一些實施例中,主動表面AS1、AS2可通過例如濕式清潔來清潔。不僅顆粒會被移除而且形成在第一連接件136的接合表面及第二連接件236的接合表面上的自生氧化物(native oxide)也可被移除。可通過例如濕式清潔製程中使用的化學品來移除形成在第一連接件136的接合表面及第二連接件236的接合表面上的自生氧化物。
在清潔半導體晶圓W的主動表面AS1及半導體晶粒200的主動表面AS2之後,可執行第一介電層132的接合表面的活化及第二介電層232的接合表面的活化以形成高的接合強度。在一些實施例中,可執行電漿活化來處理第一介電層132的接合表面及第二介電層232的接合表面。當第一介電層132的經活化的接合表面接觸第二介電層232的經活化的接合表面時,對半導體晶圓W的第一介電層132與半導體晶粒200的第二介電層232進行預接合。
在將半導體晶粒200預接合到半導體晶圓W上之後,執行半導體晶粒200與半導體晶圓W的混合接合。半導體晶粒200與半導體晶圓W的混合接合可包括用於介電接合的熱處理及用於導體接合的熱退火。在一些實施例中,執行用於介電接合的熱處理以強化第一介電層132與第二介電層232之間的接合。舉例來說,用於介電接合的熱處理可在介於從約200℃到約400℃的範圍 內的溫度下執行。在執行用於介電接合的熱處理之後,執行用於導體接合的熱退火以促進第一連接件136與第二連接件236之間的接合。舉例來說,用於導體接合的熱退火可在介於從約150℃到約400℃的範圍內的溫度下執行。在執行用於導體接合的熱退火之後,將第一介電層132混合接合到第二介電層232且將第一連接件136混合接合到第二連接件236。舉例來說,第一介電層132直接接觸第二介電層232。類似地,第一連接件136直接接觸第二連接件236。因此,第一接合結構130混合接合到第二接合結構230。
參照圖1B及圖1C,在將半導體晶粒200混合接合到半導體晶圓W之後,減小半導體晶粒200的高度H200’。舉例來說,移除半導體基板210的一部分以使得圖1C中所示的半導體晶粒200的後表面RS2’位於比圖1B中所示的後表面RS2低的水平高度上。在一些實施例中,可通過平坦化製程局部地移除半導體基板210。在一些實施例中,所述平坦化製程包括機械研磨製程、化學機械拋光(chemical mechanical polishing;CMP)製程等。如圖1C中所示,在執行平坦化製程之後,仍未顯露出TSV 212。也就是說,在此階段中,半導體基板210的厚度大於TSV 212的高度。在一些實施例中,在執行平坦化製程之後,每一半導體晶粒200具有介於從約15μm到約30μm的高度H200
參照圖1D,在半導體晶圓W上形成多個絕緣層穿孔(through insulating via;TIV)300。在一些實施例中,TIV 300 被形成為環繞半導體晶粒200且貼合到輔助連接件138。舉例來說,TIV 300被鍍覆在輔助連接件138的溝渠部分138b上。換句話說,TIV 300直接接觸輔助連接件138且與第一接合結構130實體連接及電性連接。以下將詳細闡述形成TIV 300的方法。首先,可形成保護層(未繪示)來保護半導體晶粒200。隨後,在半導體晶圓WS上形成晶種材料層(未繪示)。在一些實施例中,晶種材料層包括鈦/銅複合層且通過濺鍍製程形成。此後,在晶種材料層上形成具有開口的罩幕圖案(未繪示)。罩幕圖案的開口暴露出隨後形成的TIV 300的預期位置。舉例來說,罩幕圖案的開口可與輔助連接件138的位置對應。之後,執行鍍覆製程以在被罩幕圖案的開口暴露出的晶種材料層上形成金屬材料層(例如,銅層)。然後通過剝除製程及蝕刻製程移除罩幕圖案、未被金屬材料層覆蓋的晶種材料層以及保護層,從而形成TIV 300。然而,本公開並不僅限於此。在一些替代性實施例中,可利用其他合適的方法來形成TIV 300。舉例來說,可將預製的TIV 300拾取並放置到半導體晶圓W上。
在一些實施例中,TIV 300被形成為具有約20μm到約50μm的寬度(臨界尺寸)W300。另一方面,TIV 300的高度H300可介於約25μm與約40μm之間的範圍內。如圖1D中所示,TIV 300被形成為具有與半導體晶粒200的高度實質上相同的高度,且半導體晶粒200的後表面RS2’與TIV 300的頂表面T300位於實質上同一水平高度上。然而,本公開並不僅限於此。在一些替代性 實施例中,TIV 300可比半導體晶粒200矮或高。舉例來說,半導體晶粒200的後表面RS2’可位於比TIV 300的頂表面T300高或低的水平高度上。
應注意的是,儘管圖1B到圖1D示出在形成TIV 300之前先將半導體晶粒200混合接合到半導體晶圓W,然而本公開並不僅限於此。在一些替代性實施例中,在半導體晶粒200混合接合到半導體晶圓W之前,可將TIV 300鍍覆在半導體晶圓W上。
參照圖1E,在半導體晶圓W上形成第一包封體材料400a’,以包封半導體晶粒200及TIV 300。在一些實施例中,TIV 300及半導體晶粒200的半導體基板210未被顯露出來,且被第一包封體材料400a’很好地保護起來。舉例來說,第一包封體材料400a’的頂表面T400a’位於比TIV 300的頂表面T300及半導體晶粒200的後表面RS2’高的水平高度上。在一些實施例中,第一包封體材料400a’包括模製化合物、模製底部填充膠等。作為另外一種選擇,第一包封體材料400a’可為聚合材料,例如聚醯亞胺、環氧樹脂、丙烯酸樹脂、酚醛樹脂、BCB、PBO、或其他合適的聚合物系介電材料。在一些實施例中,第一包封體材料400a’可包含填料(filler)。作為另外一種選擇,第一包封體材料400a’可不含填料。在一些實施例中,第一包封體材料400a’可通過模製製程(例如壓縮模製製程)或旋轉塗布製程形成。在一些實施例中,在半導體晶圓W上形成第一包封體材料400a’之後,可將圖1E中所示的結構翻轉,且可將半導體晶圓W的後表面RS1薄化,以減小隨後形 成的封裝的總厚度。在一些實施例中,可通過機械研磨製程、CMP製程等將半導體晶圓W的後表面RS1薄化。應注意的是,將半導體晶圓W的後表面RS1薄化的步驟可為可選的,因此,此步驟未在圖1E中示出。
參照圖1E及圖1F,對第一包封體材料400a’、TIV 300及半導體晶粒200進行薄化直到暴露出TIV 300及TSV 212二者。在一些實施例中,可通過研磨製程(例如機械研磨製程、CMP製程等)將第一包封體材料400a’、TIV 300及半導體晶粒200薄化。在研磨第一包封體材料400a’之後,在半導體晶圓W上會形成第一包封體400a以包封半導體晶粒200及TIV 300。如圖1E及圖1F中所示,由於TSV 212嵌置在半導體晶粒200的半導體基板210中,因此半導體基板210的部分會被移除以顯露出TSV 212。同時,TIV 300的部分也被移除。在研磨之後,半導體晶粒200具有與TIV 300的頂表面T300’、第一包封體400a的頂表面T400a及TSV212的頂表面T212實質上共面的後表面RS2”。在一些實施例中,TSV 212穿透每一半導體晶粒200的至少一部分。舉例來說,TSV 212可穿透半導體晶粒200的半導體基板210。
如圖1F中所示,第一包封體400a側向包封半導體晶粒200及TIV 300。在一些實施例中,TIV 300穿透第一包封體400a。在一些實施例中,第一接合結構130的第一介電層132以及第二接合結構230的第二介電層232貼合到第一包封體400a。舉例來說,第一介電層132及第二介電層232直接接觸第一包封體400a。 在一些實施例中,第一包封體400a側向覆蓋第二介電層232。
參照圖1G,移除每一半導體晶粒200的一部分以形成多個凹槽R。舉例來說,移除半導體基板210的一部分以形成凹槽R。如圖1G中所示,TSV 212局部地位於凹槽R中。在一些實施例中,每一TSV 212的至少一部分從半導體晶粒200的半導體基板210突出。也就是說,TSV 212的頂表面T212位於比半導體晶粒200的後表面RS2'''高的水平高度上。在一些實施例中,可通過蝕刻製程局部地移除半導體基板210。蝕刻製程包括例如等向性蝕刻製程和/或非等向性蝕刻製程。舉例來說,可通過濕式蝕刻製程、乾式蝕刻製程、或其組合局部地移除半導體基板210。
參照圖1H,形成第二包封體400b以填充凹槽R。在一些實施例中,第二包封體400b包含模製化合物、模製底部填充膠等。作為另外一種選擇,第二包封體400b可為聚合材料,例如聚醯亞胺、環氧樹脂、丙烯酸樹脂、酚醛樹脂、BCB、PBO、或其他合適的聚合物系介電材料。在一些實施例中,第二包封體400b可包含填料。作為另外一種選擇,第二包封體400b可不含填料。在一些實施例中,第二包封體400b的材料可與第一包封體400a的材料相同。然而,本公開並不僅限於此。在一些替代性實施例中,第二包封體400b的材料可不同於第一包封體400a的材料。在一些實施例中,第一包封體400a及第二包封體400b可被統稱為包封體400。如圖1H中所示,第二包封體400b包封每一TSV 212的突出部分。也就是說,每一TSV 212被包封體400局部地包繞。 在一些實施例中,包封體400覆蓋半導體晶粒200的側壁及後表面RS2'''。在一些實施例中,第二包封體400b可通過包覆模製(over-molding)製程形成。舉例來說,可在第一包封體400a及TIV 300上形成第二包封體材料(未繪示)。第二包封體材料也填充凹槽R。此後,將第二包封體材料薄化直到顯露出TIV 300及TSV 212,從而形成第二包封體400b。在一些實施例中,可通過機械研磨製程、CMP製程等將第二包封體材料薄化。如圖1H中所示,第一包封體400a的頂表面T400a、TIV 300的頂表面T300’、TSV 212的頂表面T212及第二包封體400b的頂表面T400b實質上共面。
參照圖1I,在包封體400及TIV 300上形成介電層500。在一些實施例中,介電層500的材料包括聚醯亞胺、環氧樹脂、丙烯酸樹脂、酚醛樹脂、BCB、PBO或任何其他合適的聚合物系介電材料。介電層500例如可通過合適的製作技術(例如旋轉塗布、CVD、PECVD等)形成。
參照圖1J,在第一包封體400a、第二包封體400b、TSV 212及TIV 300上依序形成多個球下金屬(under-ball metallurgy;UBM)圖案600及多個導電端子700。在一些實施例中,UBM圖案600可通過以下步驟形成。首先,在介電層500中形成多個接觸開口OP。接觸開口OP至少暴露出每一TSV 212及每一TIV 300。然後,在介電層500上及接觸開口OP中形成晶種材料層(未繪示)。晶種材料層延伸到接觸開口OP中以直接接觸TSV 212及 TIV 300。在一些實施例中,晶種材料層包括鈦/銅複合層且通過濺鍍製程形成。然後,在晶種材料層上形成具有開口的罩幕圖案(未繪示)。罩幕圖案的開口暴露出隨後形成的UBM圖案600的預期位置。舉例來說,罩幕圖案的開口可暴露出位於接觸開口OP內部的晶種材料層及位於接觸開口OP附近的晶種材料層。之後,執行鍍覆製程以在被罩幕圖案的開口暴露出的晶種材料層上形成導電材料層。在一些實施例中,導電材料層的材料包括鋁、鈦、銅、鎳、鎢和/或其合金。然後通過剝除製程及蝕刻製程移除罩幕圖案及下伏的晶種材料層。剩餘的晶種材料層及導電材料層然後構成UBM圖案600。
在一些實施例中,UBM圖案600與TSV 212及TIV 300連接。因此,UBM圖案600可通過TIV 300與半導體晶圓W電性連接。同時,UBM圖案600也通過TSV 212與半導體晶粒200電性連接。如圖1J中所示,TSV 212中的至少一者與TIV 300中的至少一者同時連接到同一UBM圖案600。在一些實施例中,至少一個UBM圖案600連接到多個TSV 212。通過使UBM圖案600落在多個TSV 212上,可充分減小電阻,且可有效地增強裝置在操作期間的散熱。應注意的是,在整個公開內容中,用語「多個」指「多於一個」。在一些實施例中,每一UBM圖案600被形成為具有約40μm到約200μm的寬度W600。另一方面,兩個相鄰的UBM圖案600可具有介於約100μm與約1000μm之間的範圍內的節距。
在一些實施例中,在UBM圖案600上設置導電端子700。在一些實施例中,導電端子700通過焊劑貼合到UBM圖案600。在一些實施例中,導電端子600是例如焊料球、球柵陣列(ball grid array;BGA)球或受控塌陷晶片連接(controlled collapse chip connection;C4)凸塊。在一些實施例中,導電端子700由具有低電阻率的導電材料(例如,Sn、Pb、Ag、Cu、Ni、Bi、或其合金)製成。
參照圖1K,執行單體化製程(singulation process)以形成多個封裝10。在一些實施例中,劃切製程(dicing process)或單體化製程通常涉及用旋轉刀片或雷射光束進行劃切。換句話說,劃切製程或單體化製程是例如雷射切割製程、機械切割製程或其他合適的製程。在一些實施例中,在單體化製程期間,包封體400被切斷且半導體晶圓W被分成多個半導體晶粒100。也就是說,每一半導體晶粒100包括半導體基板110、設置在半導體基板110上的第一內連結構120、以及設置在第一內連結構120上的第一接合結構130。在一些實施例中,半導體晶粒100可被稱為封裝10的第一晶粒,而半導體晶粒200可被稱為封裝10的第二晶粒。
在一些實施例中,圖1A到圖1K中所示的步驟可被稱為「晶圓上晶片(chip on wafer;CoW)級封裝」。如圖1K中所示,半導體晶粒200堆疊在半導體晶粒100上。換句話說,多個半導體晶粒100、200被整合到單個封裝10中。因此,封裝10可被稱 為「積體電路上系統(system on integrated circuit;SOIC)封裝」。在一些實施例中,通過使用圖1A到圖1K中所示的步驟,異質(heterogeneous)半導體元件或同質(homogeneous)半導體元件可以較低的成本有效地整合到單個封裝中。舉例來說,已知良好晶粒(known-good-die;KDG)可以低成本有效地與半導體晶圓/半導體晶粒整合。另外,堆疊晶片/晶粒大小可為靈活的。此外,由於半導體晶粒100、200彼此堆疊,因此可增強封裝10的緊密性。另一方面,由於導電端子700分別通過TIV 300及TSV 212與半導體晶粒100及半導體晶粒200電性連接,因此可採用短的電路路徑。也就是說,可有效地增強封裝10的信號傳輸性能。在一些實施例中,封裝10可用於倒裝晶片(flip-chip)應用中。也就是說,封裝10可以倒裝晶片的方式進一步接合到基板(例如印刷電路板(printed circuit board;PCB)等)上。
圖2是根據本公開的一些替代性實施例的封裝20的示意性剖視圖。參照圖2,封裝20類似於圖1K中的封裝10,因此本文中省略其詳細說明。然而,在封裝20中,每一TIV 300落在多個輔助連接件138上。也就是說,多個輔助連接件138的溝渠部分138b直接接觸同一TIV 300。
在一些實施例中,由於半導體晶粒100、200彼此堆疊,因此可增強封裝20的緊密性。此外,由於導電端子700分別通過TIV 300及TSV 212與半導體晶粒100及半導體晶粒200電性連接,因此可採用短的電路路徑。也就是說,可有效地增強封裝20 的信號傳輸性能。在一些實施例中,封裝20可用於倒裝晶片應用中。也就是說,封裝20可以倒裝晶片的方式進一步接合到基板(例如PCB等)上。
圖3是根據本公開的一些替代性實施例的封裝30的示意性剖視圖。參照圖3,封裝30類似於圖1K中的封裝10,因此本文中省略其詳細說明。然而,在封裝30中,每一UMB圖案600貼合到一個TSV 212及一個TIV 300。也就是說,每一UMB圖案600直接接觸TSV 212中的一者及TIV 300中的一者。
在一些實施例中,由於半導體晶粒100、200彼此堆疊,因此可增強封裝30的緊密性。此外,由於導電端子700分別通過TIV 300及TSV 212與半導體晶粒100及半導體晶粒200電性連接,因此可採用短的電路路徑。也就是說,可有效地增強封裝30的信號傳輸性能。在一些實施例中,封裝30可用於倒裝晶片應用中。也就是說,封裝30可以倒裝晶片的方式進一步接合到基板(例如PCB等)上。
圖4是根據本公開的一些替代性實施例的封裝40的示意性剖視圖。參照圖4,封裝40類似於圖1K中的封裝10,因此本文中省略其詳細說明。然而,在封裝40中,每一TIV 300落在多個輔助連接件138上。也就是說,多個輔助連接件138的溝渠部分138b直接接觸同一TIV 300。另外,在封裝40中,每一UBM圖案600貼合到一個TSV 212及一個TIV 300。也就是說,每一UBM圖案600直接接觸TSV 212中的一者及TIV 300中的一者。
在一些實施例中,由於半導體晶粒100、200彼此堆疊,因此可增強封裝40的緊密性。此外,由於導電端子700分別通過TIV 300及TSV 212與半導體晶粒100及半導體晶粒200電性連接,因此可採用短的電路路徑。也就是說,可有效地增強封裝40的信號傳輸性能。在一些實施例中,封裝40可用於倒裝晶片應用中。也就是說,封裝40可以倒裝晶片的方式進一步接合到基板(例如PCB等)上。
