Description

半導體封裝
本發明實施例是有關於一種半導體封裝。
近年來,由於各種電子元件(例如,電晶體、二極體、電阻器、電容器等)的積體密度不斷提高,半導體行業已經歷了迅速的成長。在很大程度上,積體密度的此提高是由於最小特徵尺寸的不斷減小,這允許將更多元件集成到給定區域中。
這些較小的電子元件所需要佔據的面積也比先前封裝小。用於半導體的封裝類型的實例包括四面扁平包裝(quad flat pack,QFP)、引腳格陣列(pin grid array,PGA)、球格陣列(ball grid array,BGA)、倒裝晶片(flip chip,FC)、三維積體電路(three-dimensional integrated circuit,3DIC)、晶圓級封裝(wafer level package,WLP)及疊層封裝(package on package,PoP)裝置。通過在半導體晶圓級上對晶片進行堆疊來製備一些三維積體電路。由於堆疊晶片之間的內連線的長度減小,因此三維積體電路具備提高的積體密度及其他優勢,例如速度更快且頻寬更高。然而,存在與三維積體電路相關的諸多挑戰。
本發明實施例的一種半導體封裝包括積體電路、第一晶片及第二晶片。所述第一晶片包括第一接合結構及第一密封環。所述第一接合結構接合到所述積體電路且設置在所述第一晶片的第一側處。所述第二晶片包括第二接合結構。所述第二接合結構接合到所述積體電路且設置在所述第二晶片的第一側處。所述第一晶片的所述第一側向所述第二晶片的所述第一側。所述第一密封環的第一部分設置在所述第一晶片的所述第一側與所述第一接合結構之間,且所述第一部分的寬度小於所述第一密封環的第二部分的寬度。
本發明實施例的一種半導體封裝包括積體電路、第一晶片及第二晶片。所述積體電路包括導電特徵。所述第一晶片包括第一接合結構及第一密封環。所述第一接合結構接合到所述積體電路且設置在所述第一晶片的第一側處。所述第二晶片包括第二接合結構。所述第二接合結構接合到所述積體電路且設置在所述第二晶片的第一側處。所述第一晶片的所述第一側向所述第二晶片的所述第一側。所述導電特徵設置在所述第一接合結構與所述第二接合結構之間且電連接到所述第一接合結構及所述第二接合結構,且從俯視角度看,所述第一密封環不與所述導電特徵重疊。
本發明實施例的一種半導體封裝包括積體電路、第一晶片及第二晶片。所述第一晶片包括位於所述第一晶片的第一側處的第一接合結構及第一導電特徵。所述第一接合結構接合到所述積體電路且設置在所述積體電路與所述第一導電特徵之間。所述第一導電特徵實體連接到所述第一接合結構。所述第二晶片包括位於所述第二晶片的第一側處的第二接合結構。所述第二接合結構接合到所述積體電路,且所述第一晶片的所述第一側向所述第二晶片的所述第一側。所述第一導電特徵與所述第一晶片的所述第一側之間的區是無密封環的區。

接合結構120、120A、120B設置在內連線結構110的表面(例如,前表面)之上且設置在至少一個接合介電層122中。在一些實施例中,接合結構120A、120B沿著側102a設置,且接合結構120可沿著側102b、102c、102d排列。鄰近的兩個接合結構120、120A、120B之間的距離可相同或不同。在一些實施例中,接合結構120、120A、120B包括接合導電特徵,例如接墊124a及/或接合通孔124b。接合通孔124b電連接到內連線結構110,且接墊124a電連接到接合通孔124b。在一些實施例中,接合介電層122包含氧化矽、氮化矽、聚合物或其組合。接合導電特徵可包含鎢(W)、銅(Cu)、銅合金、鋁(Al)、鋁合金或其組合。在一些實施例中,阻擋層可設置在接合導電特徵與接合介電層122之間。所述阻擋層包含Ta、TaN、Ti、TiN、CoW或其組合,舉例來說。在一些實施例中,接合結構120、120A、120B是經由雙鑲嵌製程形成。在一些實施例中,接合結構120、120A、120B是經由多次單鑲嵌製程形成。在一些實施例中,接合結構120、120A、120B是經由電鍍製程形成。
在一些實施例中,導電特徵116實體連接且電連接到接合結構120A、120B。具體來說,導電特徵116接觸接合結構120A、120B的接合通孔124b,且接合通孔124b設置在接墊124a與導電特徵116之間。在一些實施例中,接合結構120A、120B可在第一方向(即,第一晶片100A及第二晶片100B在積體電路200上的堆疊方向)上延伸,且導電特徵116可在與第一方向實質上垂直的第二方向(即,第一晶片100A及第二晶片100B的排列方向)上延伸。在一些實施例中,導電特徵116進一步電連接接合結構120與接合結構120A或接合結構120與接合結構120B。在一些實施例中,導電特徵116包括在內連線結構110中,然而,本發明並不僅限於此。舉例來說,在一些實施例中,導電特徵116可以是設置在半導體基底104中、接合介電層122中或設置在其他適合的位點中的其他導電特徵,且直接接觸接合結構120A、120B。
在一些實施例中,第一晶片100A及第二晶片100B還包括密封環130A、130B。密封環130A、130B設置在半導體基底104的表面(例如,前表面)之上。具體來說,密封環130A、130B設置在裝置層之上且與裝置層電絕緣,並且位於內連線結構110旁邊。在一些實施例中,密封環130A、130B例如連續地設置在側102a、102b、102c、102d處。如圖1A中所示,從俯視角度看,密封環130A、130B具有環形狀或任何適合的形狀。在一些實施例中,接合結構120A、120B設置在密封環130A、130B內且被密封環130A、130B環繞。
在一些實施例中,第一晶片100A的密封環130A具有部分132A及部分134A,且部分132A與部分134A實體連接。類似地,第二晶片100B的密封環130B具有部分132B及部分134B,且部分132B與部分134B實體連接。在一些實施例中,部分132A、132B設置在側102a處,且部分134A、134B設置在側102b、102c、102d處。在一些實施例中,部分132A、132B可以是線條形且沿著側102a延伸。部分134A、134B可以是U形的且沿著側102b、102c、102d連續地設置。第一晶片100A的第一部分132A鄰近於側102a設置。
在一些實施例中,接合結構120A、120B與部分132A、132B之間的最短距離D1A 、D1B 是接墊124a的最外側邊緣與部分132A、132B的最內側邊緣之間的距離。在一些實施例中,距離D1A 、D1B 例如可處於20微米到100微米的範圍中。在一些實施例中,部分132A、132B與側102a之間的最短距離D2A 、D2B 例如可處於5微米到100微米的範圍中。在一些實施例中,距離D2A 、D2B 也是在進行矽單體化之後剩餘矽的寬度。在一些實施例中,舉例來說,密封環130A、130B與每一側102a、102b、102c、102d之間的最短距離(未示出)可實質上相同。
在一些實施例中,部分132A、132B具有均勻的寬度W1A 、W1B ,且部分134A、134B具有均勻的寬度W2A 、W2B 。部分132A、132B的寬度W1A 、W1B 小於部分134A、134B的寬度W2A 、W2B 。即,密封環130A、130B的一部分(即,部分132A、132B)在側102a處變窄。在一些實施例中,舉例來說,寬度W1A 比寬度W2A 小至少5微米,且寬度W1B 比寬度W2B 小至少5微米。在一些實施例中,寬度W1A 、W1B 可處於5微米到45微米的範圍中,且寬度W2A 、W2B 可處於10微米到50微米的範圍中。在一些實施例中,部分132A、132B與部分134A、134B可同時形成。
在本文中,當元件被闡述為“處於實質上相同的水平高度時”,這些元件在同一層中形成在實質上相同的高度處或具有經由同一層嵌入的相同的位置。在一些實施例中,處於實質上相同的水平高度處的元件是由相同材料經由相同的製程步驟形成。在一些實施例中,處於實質上相同的水平高度的元件的表面實質上共面。舉例來說,如圖1B中所示,密封環130A、130B與內連線結構110處於實質上相同的水平高度處。詳細來說,密封環130A、130B可包括多個導電特徵136,例如導線及位於所述導線之間的插塞。密封環130A、130B的導電特徵136與內連線結構110的導電特徵114、116處於實質上相同的水平高度處。
在一些實施例中,區RA 、RB 被界定為位於側102a與內連線結構110的最外側邊緣(即導電特徵114、116的最外側邊緣)之間。當元件(例如,密封環130A、130B的部分132A、132B)設置在區RA 、RB 中時,需要用於所述元件的空間,且導電特徵116與側102a之間的距離會增大。此外,由於接合結構120A、120B實體連接到導電特徵116且設置在導電特徵116之上,因此接合結構120A、120B(即接墊124a的最外側邊緣)與側102a之間的距離也會增大。
仍參考圖1A及圖1B,積體電路200例如可以是特殊應用積體電路(ASIC)晶片、類比晶片、感測器晶片、無線射頻晶片、電壓調節器晶片或記憶體晶片。積體電路200與第一晶片100A及第二晶片100B可以是同一類型的晶片或不同類型的晶片。在一些實施例中,積體電路200可以是主動元件或被動元件。在一些實施例中,積體電路200的尺寸大於第一晶片100A及第二晶片100B的尺寸。在本文中,用語“尺寸”被稱為長度、寬度及/或面積。在一些實施例中,積體電路200的面積大於第一晶片100A及第二晶片100B的總面積。
在一些實施例中,積體電路200包括半導體基底204、內連線結構210、多個接合結構220及多個導電特徵216。
內連線結構210類似於內連線結構110。類似地,內連線結構210設置在半導體基底204的表面(例如,前表面)之上。具體來說,內連線結構210設置在裝置層之上且電連接到所述裝置層。在一些實施例中,內連線結構210包括至少一個絕緣層212及多個導電特徵214、216。導電特徵214、216設置在絕緣層212中且彼此電連接。絕緣層212暴露出導電特徵的一部分(例如,最外側導電特徵216)。
接合結構220類似於接合結構120A、120B。類似地,接合結構220設置在內連線結構210的表面(例如,前表面)之上。在一些實施例中,接合結構220設置在至少一個接合介電層222中且包括接合導電特徵,例如接墊224a及/或接合通孔224b。接合通孔224b電連接到內連線結構210,且接墊224a電連接到接合通孔224b。
在一些實施例中,接合結構120A、120B及接合結構220將第一晶片100A及第二晶片100B與積體電路200面對面接合在一起。在一些實施例中,在將第一晶片100A及第二晶片100B接合到積體電路200之前,先將接合結構120A、120B與接合結構220對齊,以使得接墊124a接合到接墊224a且接合介電層122接合到接合介電層222。在一些實施例中,可使用光學感測方法來實現接合結構120A、120B與接合結構220的對齊。在實現對齊之後,經由混合接合(包括金屬對金屬接合及電介質對電介質接合)將接合結構120A、120B與接合結構220接合在一起。
在將第一晶片100A及第二晶片100B接合到積體電路200之後,第一晶片100A及第二晶片100B分別電連接到積體電路200。另外,導電特徵216直接電連接第一晶片100A與第二晶片100B。具體來說,導電特徵216電連接且實體連接接合到第一晶片100A的接合結構120A的接合結構220與接合到第二晶片100B的接合結構120B的接合結構220。在一些實施例中,導電特徵216的端子實體連接到與第一晶片100A及第二晶片100B的接合結構120A、120B接合的接合通孔224b。接合通孔224b設置在接墊224a與導電特徵216之間。導電特徵216在第一晶片100A的接合結構120A與第二晶片100B的接合結構120B之間延伸。在一些實施例中,接合結構220可在第一方向(即,第一晶片100A及第二晶片100B在積體電路200上的堆疊方向)上延伸,且導電特徵216可在與第一方向實質上垂直的第二方向(即,第一晶片100A及第二晶片100B的排列方向)上延伸。在一些實施例中,導電特徵216是內連線結構210的最外側導電特徵,然而,本發明並不僅限於此。舉例來說,在一些實施例中,導電特徵216可以是設置在半導體基底204中、接合介電層222中或設置在其他適合的位點中的其他導電特徵。另外,導電特徵216也可被稱為連接特徵或橋接結構。
在一些實施例中,舉例來說,密封環130A、130B的部分132A、132B可在與側102a平行的第一方向上延伸,且導電特徵216可在與側102a實質上垂直的第二方向上延伸。因此,如圖1A中所示,從俯視角度看,導電特徵216可與密封環130A、130B的部分132A、132B部分地重疊以形成重疊區OPRA 、OPRB 。在一些實施例中,舉例來說,導電特徵216彼此實質上平行。在一些實施例中,舉例來說,導電特徵216可與第一晶片100A及第二晶片100B的側102a、102c(例如,短的側)平行。
在一些實施例中,導電特徵216例如可以是線條形的。舉例來說,導電特徵216的節距可處於0.04微米到5微米的範圍中。在一些實施例中,導電特徵216可包含鎢(W)、銅(Cu)、銅合金、鋁(Al)、鋁合金或其組合。在一些實施例中,阻擋層可設置在導電特徵216與絕緣層212之間。阻擋層包含Ta、TaN、Ti、TiN、CoW或其組合,舉例來說。在一些實施例中,導電特徵216是經由雙鑲嵌製程形成。在一些實施例中,導電特徵216是經由多次單鑲嵌製程形成。在一些實施例中,導電特徵216是經由電鍍製程形成。
在一些實施例中,導電特徵216電連接彼此最接近的接合結構120A、120B。因此,導電特徵216提供對應接合結構120A、120B之間的最短導電路徑。因此,第一晶片100A與第二晶片100B彼此可高效地聯通(talk),即導電特徵216提供晶片到晶片的聯通路徑TP。在一些實施例中,導電特徵216被設置成跨越密封環130A的部分132A、第一晶片100A與第二晶片100B之間的間隔及密封環130B的部分132B。因此,晶片到晶片的聯通路徑TP的長度實質上等於以下各項的總和:部分132A與第一晶片100A的接合結構120A之間的距離D1A 、部分132A的寬度W1A 、部分132A與第一晶片100A的側102a之間的距離D2A 、第一晶片100A的側102a與第二晶片100B的側102a之間的距離DAB 、部分132B與第二晶片100B的側102a之間的距離D1B 、部分132B的寬度W1B 及部分132B與第二晶片100B的接合結構120B之間的距離D2B 。在一些實施例中,距離D1A 、D2A 可取決於微影的製程裕度或導電元件之間的絕緣要求。距離DAB 可取決於包封體的間隙填充能力。在一些實施例中,經由將密封環130A、130B的部分132A、132B窄化,會減小寬度W1A 、W1B 。因此,可縮短晶片到晶片的聯通路徑TP。在一些實施例中,舉例來說,晶片到晶片的聯通路徑TP的長度可等於或小於70微米。此外,由於密封環130A、130B的位於側102a處的部分132A、132B的寬度W1A 、W1B 小於密封環130A、130B的位於其他側102b、102c、102d處的部分134A、134B的寬度,因此接合結構120A與側102a之間的距離小於接合結構120與其他側102b、102c、102d之間的距離。舉例來說,接合結構120A與側102a之間的距離(即,距離D1A 、寬度W1A 及距離D2A 的總和)小於接合結構120與側102a之間的距離D3。
在一些實施例中,由於接合結構120A、120B的接墊124a的最外側邊緣設置在導電特徵116的最外側邊緣內,因此接墊124a的最外側邊緣與導電特徵116的最外側邊緣之間形成額外距離。因此,接合結構120A、120B與部分132A、132B之間的最短距離D1A 、D1B 大於導電特徵116與部分132A、132B之間的最短距離D4。在一些實施例中,距離D4處於20微米到100微米的範圍中。然而,在一些實施例中,接合結構120A、120B例如可被設置成更靠近部分132A、132B,接合結構120A、120B的最外側邊緣可與導電特徵116的最外側邊緣實質上齊平。因此,不需要額外距離。因此,可減小最短距離D1A 、D1B ,且縮短晶片到晶片的聯通路徑TP的長度。
在一些實施例中,圖1B的半導體封裝1中還包括包封體302、重佈線層結構304、多個接墊310及鈍化層312。在一些實施例中,舉例來說,半導體封裝1可以是需要極短的聯通路徑的高性能多晶片封裝。
包封體302設置在積體電路200之上且設置在第一晶片100A及第二晶片100B旁邊。具體來說,包封體302環繞第一晶片100A及第二晶片100B的側102a、102b、102c、102d,暴露出第一晶片100A及第二晶片100B的頂部且覆疊在積體電路200的表面(例如,前表面)上。在一些實施例中,第一晶片100A及第二晶片100B的表面(例如,後表面)與包封體302的頂表面實質上共面。在一些實施例中,包封體302包含模塑化合物。所述模塑化合物可包含樹脂及填充劑。在替代實施例中,包封體302包含氧化矽、氮化矽或其組合。包封體302可經由旋轉塗布、層壓、沉積等來形成。
在一些實施例中,多個電介質穿孔可設置在包封體302中且與內連線結構210及將形成的重佈線層結構304電連接。在一些實施例中,電介質穿孔包括導電通孔。所述導電通孔包含銅、銅合金、鋁、鋁合金或其組合。在一些實施例中,電介質穿孔還包括位於導電通孔與包封體302之間的擴散阻擋層。所述擴散阻擋層包含Ta、TaN、Ti、TiN、CoW或其組合。
重佈線層結構304設置在第一晶片100A及第二晶片100B的表面(例如,後表面)之上且設置在包封體302之上。重佈線層結構304包括交替堆疊的至少一個介電層306及至少一個導電層308。在一些實施例中,重佈線層結構304的一部分電連接到矽穿孔106。在一些實施例中,重佈線層結構304的另一部分可電連接到電介質穿孔以與積體電路200電連接。在一些實施例中,介電層306包含光敏材料,例如聚苯並噁唑(polybenzoxazole,PBO)、聚醯亞胺(polyimide,PI)、苯環丁烷(benzocyclobutene,BCB)、其組合等。在一些實施例中,導電層308包含銅、鎳、鈦、其組合等。
接墊310設置在重佈線層結構304之上。在一些實施例中,接墊310是凸塊下金屬(under bump metallization,UBM)接墊。接墊310包含金屬或金屬合金。接墊310包含鋁、銅、鎳或其合金。
鈍化層312覆蓋介電層306且覆蓋接墊310的邊緣部分,且暴露出接墊310的中心部分。在一些實施例中,鈍化層312包含氧化矽、氮化矽、苯環丁烷(BCB)聚合物、聚醯亞胺(PI)、聚苯並噁唑(PBO)或其組合。
導電連接件314安裝到接墊310。在一些實施例中,導電連接件314可以是球格陣列(BGA)連接件、焊球、金屬柱等。舉例來說,可經由安裝製程及回流製程來形成導電連接件314。
在一些實施例中,密封環的鄰近於另一晶片的一部分具有比密封環的其他部分窄的寬度。因此,用於所述密封環的所述部分的空間可減小,且接合結構可更靠近另一晶片。因此,可縮短鄰近晶片的接合結構之間的聯通路徑,且可提高半導體封裝的性能。
圖2A是根據一些實施例的半導體封裝的俯視圖,且圖2B是根據一些實施例的半導體封裝沿著圖2A所示線I-I的剖視圖。為說明的簡明及清晰起見,圖2A的簡化俯視圖中僅示出幾個元件,例如第一晶片及第二晶片、積體電路、密封環、接合結構及導電特徵,且這些元件未必處於同一平面中。
圖2A及圖2B的半導體封裝2類似於圖1A及圖1B的半導體封裝1。因此,下文詳細說明半導體封裝2與半導體封裝1之間的差異,且本文中不再贅述這兩者之間的類似性。
參考圖2A及圖2B,半導體封裝2包括第一晶片100A、第二晶片100B及積體電路200。第一晶片100A及第二晶片100B接合到積體電路200。在一些實施例中,第一晶片100A的接合結構120A接合到積體電路200的接合結構220,且第二晶片100B的接合結構120B接合到積體電路200的接合結構220。另外,積體電路200的導電特徵216電連接接合結構220,以電連接第一晶片100A與第二晶片100B。
在一些實施例中,第一晶片100A及第二晶片100B具有密封環130A、130B。在一些實施例中,舉例來說,密封環130A、130B僅設置在側102b、102c、102d處。密封環130A、130B可沿著側102b、102c、102d連續地設置。換句話說,側102a處不設置密封環。具體來說,側102a與連接到接合結構120A、120B的導電特徵116之間的區RA 、RB 不設置密封環。換句話說,區RA 、RB 是無密封環的區。因此,如圖2A中所示,從俯視角度看,密封環130A、130B不與導電特徵216重疊。在一些實施例中,密封環130A、130B例如可以是U形的。
在一些實施例中,由於側102a與連接到接合結構120A、120B的導電特徵116之間的區RA 、RB 中不設置晶片的密封環或任何其他元件,因此不需要用於密封環或任何其他元件的空間。在一些實施例中,舉例來說,區RA 、RB 中僅存在介電層(即,絕緣層112)。因此,晶片到晶片的聯通路徑TP實質上等於以下各項的總和:第一晶片100A的接合結構120A與側102a之間的距離DA 、第一晶片100A與第二晶片100B之間的距離DAB 及第二晶片100B的接合結構120B與側102a之間的距離DB 。接合結構120A、120B與側102a之間的距離DA 、DB 小於接合結構120與其他側102b、102c、102d之間的距離(例如,距離D3)。在一些實施例中,所述第一晶片100A及第二晶片100B的接合結構120A、120B與側102a之間的距離DA 、DB 取決於第一晶片100A及第二晶片100B的微影或單體化或放置製程的製程裕度。在一些實施例中,距離DA 、DB 例如可處於25微米到200微米的範圍中。在一些實施例中,距離DAB 例如可處於10微米到100微米的範圍中。在一些實施例中,晶片到晶片的聯通路徑的長度例如可減小到60微米或減小得更多。在一些實施例中,經由移除密封環的位於接合結構與鄰近於另一晶片的側之間的一部分,可縮短晶片之間的聯通路徑。
在一些實施例中,接合結構120A、120B例如可被設置成更靠近導電特徵116的最外側邊緣,接合結構120A、120B的最外側邊緣可與導電特徵116的最外側邊緣實質上齊平。因此,可進一步減小距離DA 、DB ,且可縮短晶片到晶片的聯通路徑TP的長度。
圖3A是根據一些實施例的半導體封裝的俯視圖,且圖3B是根據一些實施例的半導體封裝沿著圖3A所示線I-I的剖視圖。為說明的簡明及清晰起見,圖3A的簡化俯視圖中僅示出幾個元件,例如第一晶片及第二晶片、積體電路、接合結構及導電特徵,且這些元件未必處於同一平面中。
圖3A及3B的半導體封裝3類似於圖1A及圖1B的半導體封裝1。因此,下文詳細說明半導體封裝3與半導體封裝1之間的差異,且本文中不再贅述這兩者之間的類似性。
參考圖3A及圖3B,半導體封裝3包括第一晶片100A、第二晶片100B及積體電路200。第一晶片100A及第二晶片100B接合到積體電路200。在一些實施例中,第一晶片100A的接合結構120A接合到積體電路200的接合結構220,且第二晶片100B的接合結構120B接合到積體電路200的接合結構220。另外,積體電路200的導電特徵216電連接接合結構220,以電連接第一晶片100A與第二晶片100B。
在一些實施例中,第一晶片100A及第二晶片100B中不存在密封環。換句話說,區RA 、RB 是無密封環的區,且第一晶片100A及第二晶片100B可以是無密封環的晶片。因此,側102a與連接到接合結構120A、120B的導電特徵116之間的區RA 、RB 之間不設置密封環。
在一些實施例中,由於側102a與導電特徵116之間的區RA 、RB 中不設置晶片的密封環或任何其他元件,因此不需要用於密封環或任何其他元件的空間。在一些實施例中,舉例來說。區RA 、RB 中僅存在介電層(即,絕緣層112)。因此,晶片到晶片的聯通路徑TP實質上等於以下各項的總和:第一晶片100A的接合結構120A與側102a之間的距離DA 、第一晶片100A與第二晶片100B之間的距離DAB 及第二晶片100B的接合結構120B與側102a之間的距離DB 。接合結構120A、120B與側102a之間的距離DA 、DB 實質上等於接合結構120與其他側102b、102c、102d之間的距離(例如,距離D3)。
在一些實施例中,第一晶片100A及第二晶片100B的接合結構120A、120B與側102a之間的距離DA 、DB 取決於第一晶片100A及第二晶片100B的微影或單體化或放置製程的製程裕度。在一些實施例中,距離DA 、DB 例如可處於25微米到200微米的範圍中。在一些實施例中,距離DAB 例如可處於10微米到100微米的範圍中。在一些實施例中,舉例來說,晶片到晶片的聯通路徑的長度可減小到60微米或減小得更多。在一些實施例中,經由提供無密封環的晶片,可縮短晶片之間的聯通路徑。
在一些實施例中,接合結構120A、120B可被設置成更靠近導電特徵116的最外側邊緣,舉例來說,接合結構120A、120B的最外側邊緣可與導電特徵116的最外側邊緣實質上齊平。因此,可進一步減小距離DA 、DB ,且晶片到晶片的聯通路徑TP的長度可較短。
在以上實施例中,第一晶片100A與第二晶片100B採用相同的技術以減小接合結構120A、120B與側102a之間的距離,然而,本發明並不僅限於此。在一些實施例中,第一晶片100A與第二晶片100B可採用不同的技術以減小接合結構120A、120B與側102a之間的距離。舉例來說,在一些實施例中,可從圖1A到圖3B等中的第一晶片100A選擇第一晶片,且可從圖1A到圖3B等中的第二晶片100B選擇第二晶片。另外,儘管說明了兩個鄰近的晶片(即,第一晶片及第二晶片),但可將兩個以上的晶片接合到積體電路。
鑒於上文,可經由將元件(例如密封環)的寬度窄化、從晶片移除元件(例如密封環)的一部分或完全移除所述元件(例如密封環)來減小或消除用於所述元件的空間。因此,一個晶片的接合結構可更靠近另一晶片的接合結構。因此,鄰近晶片的接合結構之間的聯通路徑可得以縮短,且半導體封裝的性能可得以提高。
