中,中間層無需將從第二半導體晶粒的線連結回路隔開: 而且連結線前端會與介電層接觸。因此與傳統的堆疊半導 體晶粒配置相Λ,第一及第二堆疊半導體晶粒間的間隔需 做得更薄°第二半導體晶粒還需在_強壓下黏著,以減小 中間層的厚度’還需局部分平坦化第一半導體晶粒表面上 的線連結回路高度。 一旦所有的半導體晶粒附著、線路連結到基板上,便可 藉由如加熱及/或紫外線來固化半·導體封裝。在另一實施 例,中間層可在第二半導體晶粒附著之前固化。 貝 【實施方式】 現參考圖3 Α至13來描述實施例,該等圖式與一低剖面半 導體封裝有關。應明白,本發明可以多種不同形式實施, 並非限於本文所陳述的實施例。q,提供這些實施例, 所表述的就可㈣完整’從而將本發明全方位地傳達給孰 悉此項技術者。事實上,本發明包含附屬請求項中所定義 的本發明的精神與範圍内之此等實施例的可供選擇的方 法、修正、和同等物。另外 门4物另卜在下列本發明的詳盡描述 127011.doc 200840011 日中’陳述了許多特定的細節’以期讀者可透徹地瞭解本發 月。然而’-般技術者將清楚,本發明也可在無這些特定 細節的情況下實施。 /考圖3A的流程圖和圖‘13的侧視圖與俯視圖,對本發 明進行描述。本發明實施列與一半導體封裝8〇有關,封^ 80的一部A包括纟步驟2〇〇中安裝於一基板⑽的第一半導 體晶粒100,如圖4和5中所示。晶粒100在已知的黏著或晶 ,連結製程中可透過晶粒附著黏著層1G4安裝於基板102。 曰曰粒附著黏著層1G4可以是如結構已知的環氧化合物,曰 本Nm〇 Denko公司、加州Abelstik公司和加州公司 均有售。如下文所解釋的,黏著層1〇4可用作黏著液體, 其在回焊製程中固化之前一直保持該狀態。 儘官之於本發明並非關鍵,基板1〇2可有多種不同的晶 片承載媒介,包括一 PCB、一引線框、一捲帶式自動連結 (TAB)捲帶。當基板1〇2是一 pCB時,基板可由一包括於其 上形成的一頂部和/或底部導電層的核心組成。核心可以 疋各種介電材料,例如,聚硫亞胺壓片、包括fr4和fr5 的環氧樹脂、雙馬來亞醯胺三氮六環(bismaleimide triazine,BT)或此類物質。 導電層可由所知的用於基板上的銅、銅合金、鍍銅、鍍 銅合金、合金42(42FE/58NI)、銅鍍鋼或其他金屬或物質組 成。導電層可蝕刻至一用於半導體晶粒和外部裝置之間信 號交流的傳導圖案上。在導電層中,還用到虛設圖案,是 為了減小由於基板内不均勻的熱膨脹而造成的在基板上的 127011.doc -10- 200840011 機械應力。基板ι〇2還另包括組成接觸墊(圖5)和/或接 觸指狀元件(如一例子中,封裝80是一 LGA封裝)的裸露金 屬片段。可將接觸墊和指狀元件上鍍金一層或多層,例如 透過一此項技術中已知的電鍍製程。 步驟200中’將半導體晶粒100安裝至基板102後,連結 線106可在晶粒1〇〇上的連結墊1〇8(圖5)和步驟中基板 102上的連結墊110之間附著。連結線ι〇6可透過一已知的 線連結製程安裝。在實施例中,線連結製程可以是低剖面 線連結製程,例如反轉連結製程。在圖4和5中,晶粒1〇〇 的兩相對的側面上有線連結。在本發明的另一實施例中, 線連結106可設在晶粒100的一邊、三邊或四邊。 在步驟204中,可在晶粒1〇〇的暴露表面塗上中間層 120。中間層12〇是已知組成物的電絕緣黏性環氧化合物, 日本NiU〇 Denk0公司、加州Abelstik公司和加州公 司均有售。中間層120用作黏著液體,在下文所解釋的回 焊製程之前一直保持黏著液體的狀態。在實施例中,中間 層120是被視為液體使用的,但是卻有相當強的黏性以在 機械上支撐置KKO上的第二半導體晶粒。在實施例中, 黏性可達如約1-2X1G6厘泊,但應明自,在其他的實施例 中,黏度可高於或低於該值。中間層的材料可與用作黏著 層104的材料一樣或不同。在另一實施例中,在中間層12〇 内會用到隔離球狀物。隔離球狀物可以是聚合物球體,作 為晶粒100和其上安裝的一第二晶粒之間的隔離物。此類 隔離球狀物在此項技術中是廣4人知❸,例如在美國專利 12701 l.doc • 11 - 200840011 案第6,650,019號中即有闡述,其標題為:,,包括堆疊半導 體晶粒的半導體封裝之製造方法”,其專利的全部内容以 引用的方式併入此文。 如圖4和5,在一實施例中 可將中間層120塗在晶粒1 〇〇
的至/大體上整個表面上(部分邊緣可能有黏性物質,也 可能沒有)。層120的黏著材料塗布致使線連結回路1〇6部 分掩埋在層12〇中。也就是說,與連結塾⑽相鄰的線連結 106的部分以及連結回路的前端部分都掩埋於中間層 中。因中間層12〇僅塗在晶粒1⑽的表面上,從晶粒1〇〇佔 用面積延伸出來的線106的部分並未嵌入在中間層120中。 不僅將封裝80内堆疊的半導體晶粒黏著在一起中間層 12 0還使兩個堆疊的半導體晶粒之間空出一些空間以容納 線連結回路1G6的位置1而,從下—個相鄰的半導體晶 粒’中間層上並不需要額外的空間去分隔線連結回路 106。尤其在先前的技術中’連結線所嵌入的黏著層需足 夠厚以確保連結線不會受下—個㈣晶粒下表面短路的影 響。然而,在下文更詳盡的描述中,附著於中間層12〇上 的第二晶粒的表面是電絕緣體。依此,不同於先前技術, 從下-個相鄰的晶粒開始]間層12〇不需分隔線連結回 路106 ’而較之傳統堆疊半導體晶粒構造,堆疊晶粒間的 間隔j薄。例如’中間層12〇的厚度可以是25_5〇㈣,而 在先前技術中是75 μηι。應明白,在本發明的其他實施例 中’中間層120的厚度也可小於25_或大於5〇_。 如上所指示的,在步驟·中’可將一第二半導體晶粒 127011.doc •12- 200840011 122堆疊在中間層12〇上,如圖6和7所示。根據本發明,在 半導體晶粒122和中間層120之間的介面處可形成介電層 130。在實施例中,介電層13〇也可在半導體晶粒122背面形 成。介電層130可透過各種已知的方法在半導體晶粒122上 形成。在一實施例中,層13 〇可以是一壓貼於半導體晶粒 122背面的黏性環氧化合物,並如下文所說,在中間層 之前或和其一起被固化。介電層13〇還可在半導體晶粒122 製造過程中形成於晶圓級。例如,當晶圓未經背面研磨 時,可在半導體的製造過程中生長介電層13〇。介電層 還可透過各種製程,包括化學電鍍、化學氣相沈 * 只 / νΓΛ 發、喷濺、鐳射沈積、分子光束磊晶術、噴射、噴繪、絲 網印刷術在半導體晶粒122的背面上沈積介電膜而獲得。在 晶圓未經背面研磨的情況下,會在晶圓的製造過程中沉積 介電膜。在晶圓受到背面研磨的情況下,會在背面研磨製 程之後、晶粒122被附著於中間層12〇之前沉積介電膜。這 可以是在晶粒122從晶圓上分割之前或之後。也考慮形成介 電層130的其他沈積方法或技術。在實施例中,介電層 的厚度在10 μηι和20 μιη之間,但應明白,介電層13〇的厚度 可小於或大於本發明之替代實施例中之介電層厚度。 大於2 0也可小於1 〇。 一旦晶粒122附著於中間層12〇,在步驟21〇中可用已知的 線連結製程中之連結線124將晶粒122線連結於基板1〇2。 本發明的實施例中,可能只有一對半導體晶粒1〇〇和 122。但是在進一步的實施例中,有多於兩個半導體晶粒 127011.doc -13- 200840011 互相堆疊。在這樣的實施例中,如圖3A的虛線所指示,步 驟204 ’以較上層的晶粒的上纟面塗上黏㈣,步驟 即附著另θθ粒,步驟21 〇,即給每個堆疊在晶粒 122上的另外的半導體晶粒重複線連結另一晶粒。 正如上文所指出的,在中間層12〇上施加可有效地支撐 半導體晶粒122的黏性,而不用過度平坦化線連結回路
106仁是,虽半導體晶粒122附著於中間層〗2〇,需在中 間層施加壓力以減小中間層12〇的厚度。這樣做,連結線 106的前端就會接觸介電層13〇,如圖7所示。但是,由於 介電層130將連結線1〇6的每股相互隔開、同時也與半導體 晶粒122分隔,因此不會發生短路。 如圖8,進一步的實施例,需用一壓縮負載將半導體晶 粒122安瓜至封裝14〇,以減小中間層12〇的厚度,如上文 所述,另外局部平坦化半導體1〇〇表面上方連結線1〇6的高 度。層120的厚度和連結線1〇6的高度應減小到一不影響連 接至半導體晶粒1〇〇上連結線的結構完整之值。如上文所 述在貝施例中,該厚度是在25 μπι至50 μηι之間,而在其 他實施例中,也可小於25 μπι或大於5〇 μιη。 一旦所有的半導體晶粒都安裝妥當,且線連結至基板 1〇2上,在步驟212的回焊製程中,半導體封裝8〇會被固 化,以使包括中間層12〇和晶粒附著層1〇4的各黏著層變 更可用各種已知的方法固化,包括諸如加熱和/或紫外 線;固化取決於黏性材料。 在以上參考圖3Α的流程圖所描述的實施例中,封裝肋是 1270Il.doc 14 200840011 在所有的半導體晶粒均堆疊好、連結線完成後才固化。在 參考圖3B的流程圖所描述的本發明的另一實施例中,在安 裝半導體晶粒122之前,中間層12〇和晶粒連結層1〇4可在 步驟206固化(本實施例中,層1〇4和12〇可在步驟2〇6中同 時固化或先後固化)。在該實施例中,介電層π〇可以是或 包括一可固化黏著劑,這樣半導體晶粒丨22就可以附著於 一固化的中間層120,其後並在後續固化製程中牢牢附 著。還考慮晶粒連結層104和/或中間層120在步驟206中可 部分固化至b-階段。而半導體晶粒丨22完全安裝好後,就 可使層104和/或106全部固化。 在上述實施例中,中間層i2〇可以是黏性材料。但是, 應明白,當130是黏性材料時,中間層12〇就無需是黏性材 料。在此實施例中,層12〇被用作連結線1〇6周圍的液體塗 上’僅充當分隔晶粒1 〇〇和12〇、使連結線丨〇6的每股相互 絕緣的間隔層。此實施例中,晶粒1〇〇和122透過電絕緣黏 著層130相互附著。 圖9-12所示的是本發明的另一實施例。在該實施例中, 並不疋在半導體晶粒1 〇〇的大體上整個表面塗上中間層 120,而是僅作為離散量的黏性材料144塗在半導體晶粒 100上之接觸墊108上並與其鄰接。特別地,黏性材料144 可塗在包括連結墊108之半導體晶粒ι〇〇的第一區域,而不 塗在不包括連結墊的第二區域。該實施例適用於當接觸墊 108的一面、兩面、三面或四面在半導體晶粒1⑽上時。 在另一實施例中,如圖丨丨和12所示,當第二半導體晶粒 127011.doc -15- 200840011 122附著於封裝時,需用壓縮力稍加平坦化黏著層Μ#。如 上文所指,除了平坦化黏著層144,壓縮力還可減小半導 體晶粒100表面上線連結回路1〇6前端的高度。其後,在固 化製程中,黏性區域可進一步平坦化,以使黏著層144延 展到晶粒1〇〇的表面。應明白,液體黏著層144並非一旦與 晶粒122附著後及/或在後續固化製程後,即覆蓋晶粒1〇〇 的整個表面。另外,在有些實施例中,半導體晶粒122上 的介電層130亦由可固化的黏著劑組成,黏性材料144和介 電層130會在晶粒100和122之間的介面鋪展開來以填充其 間的空隙。 圖9-12所示實施例中,一旦晶粒122附著於晶粒1〇〇,第 一半導體曰曰粒12 2便連同線連結12 4透過一已知的線連結方 法線連結至基板102。接著封裝如上所述被固化。 在上述這些實施例中,從晶粒1〇〇和122出來的連結線可 以是未塗布的金,但也可是銅、鋁或其他金屬。在本發明 的進一步實施例中,晶粒100和/或122的連結線用絕緣聚 合物事先(如在被嵌於中間層120之前)絕緣的,以使電線表 面為電絕緣。已知此類事先絕緣連結線是為了防止相鄰連 結線間發生短路。適合本發明使用的事先絕緣連結線之兩 例揭露於:美國專利申請案第5,396,104號,標題為:”樹 脂塗層連結線及其製造方法,以及半導體裝置,,及美國公 開專利申請案第2004/0124545號中,標題為:π高密度積 體電路及其封裝方法”,其全部内容以引用的方式併入本 文。使用事先絕緣連結線的實施例可在具備或不具備中間 1270ll.doc -16 - 200840011 層120的情況下操作。在沒有中間層12〇的情況下操作的此 類實施例中’介電層13〇是用於附著晶粒的黏著劑。 如圖13,根據以上任何所述實施例,堆疊的晶粒結構形 成之後,在步驟214中,該架構被包入一成型化合物15〇, 而在步驟216中’被單一化’以形成一完成的半導體晶粒 封裝160。成型化合物15〇是已知的一種環氧化合物,如 Sumit〇m_ Nitt〇 Denk〇公司均有售,這兩家公司總部都在 日本。然後,在步驟218中,完成的封裝⑽可視需要封入 一蓋子。 在很多實施例中,上述半導體晶粒可包括—個或多個快 閃記憶體晶片、控制器如專用積體電路,這樣,封裝WO 就可用作快閃記憶體裝置。應明白,在本發明的進:步實 施例中,封裝160可包括配置的半導體晶粒以發揮其他^ 用。 幻文對於本鲞明的詳盡描述旨在解析和說明,而非將本 發明拘泥於此。從上述教示,也可作出修改和變化。選擇 這些說明的實施例,是為了儘可能以最佳方式解釋本發明 的規則和實際應用,則吏熟悉此項技術者在各種實施例中 且在各種修改下利用本發明。預期本發明範疇如附屬請求 項所定義。 【圖式簡單說明】 ,是-傳統的包括安裝在—基板上的堆疊半導體晶粒 的半導體封裝的剖面側面圖。 圖2是圖工中半導體封裝一部分的放大剖面側面圖。 1270Il.doc -17- 200840011 圖3 A是依據本發明_每 流程圖。 ““列的半導體封裝的製造方法的 圖3B是依據本發明的一每 法的流程圖。 則的丰導體封裳的製造方 側面 圖 圖4是本發明產品製造中半導體封裝-部分的剖面 圖5是圖4所示的本發明丰遙 月牛導體封裝的-部分的俯視圖。 圖6疋本發明產品製 圖 衣、〒牛V體封裝一部分的剖面側面 圖 圖7是本發明產品製造中半導體封裝一部分 的剖面側面 圖8是本發明產品製造中另一實 分的剖面側面圖。 圖9是本發明產品製造中又一 、——,…1 驵対裝一部 分的剖面侧面圖。 圖1〇是圖9的又一實施例中半導體封裝的一 施例中半導體封裝一 施例中半導體封裝一 部 圖 部分的俯視 的剖面側 圖11是圖9的產品製造中半導體封裝的一部分 面圖。 圖 圖12是圖9的產品製造中半導體封裝一部分的 剖面側面 面側面 圖 圖13是依據本發明實施例的一半導體封裝的剖 〇 【主要元件符號說明】 127011.doc -18- 200840011
