Description

200539298 九、發明說明： 【發明所屬之技術領域】 本發明係有關於一種半導體裝置之製造方法，以及應用 於該方法的一種半導體基板之支撑結構。 【先前技術】 由於近年來對於半導體裝置的微小化以及效能的要求 越來越高，半導體封裝也被要求要微小化並具有較高的效 •能。 9 例如，目前已經有降低半導體裝置厚度的需求。為了滿 足此需求，其有必要藉由增加背研磨製程的研磨量，降低封 裝後的半導體基板厚度，其中，半導體基板的背面，或相反 於半導體裝置元件的表面，需要被研磨以降低半導體基板的 厚度。 第1圖係顯示一半導體裝置1〇,具有一晶片級封裝（chip size package，CSP)結構，其設計可降低半導體裝置的尺寸。 • 參照第1圖，該半導體裝置ίο包括一半導體基板u， 其可以為一矽晶圓或是其他基板，具有一裝置面11A以及一 背面11B，裝置面11 a上設有半導體裝置元件，背面i i B相 反於裝置面11A。由鋁或其他材料製成的複數個電極墊1 2， 形成於該裝置面11A之上。由氮化矽（SiN)或其他材料製成 的鈍化層（passivation layer)12A則覆蓋於裝置面11A上之 除電極墊1 2以外的位置。該鈍化層1 2A由鈍化層1 3所覆蓋， 鈍化層13由樹脂，例如，聚醯亞胺。此外，該鈍化層13由 密封樹脂層1 5所覆蓋。 2001-7107-PF 5 200539298 導線部1 4由銅所製成，設於鈍化層1 2 A以及鈍化層1 3 的開口之中，並連接至電極墊丨2。該導線部i 4的佈局部分 延伸至該鈍化層1 3之上。導線柱丨6立設於鈍化層丨3上的 導線部14之上，並與導線部14連接。每一導線柱16的側 表面由該密封樹脂層1 5所環繞，但導線柱丨β上端暴露於密 封樹脂層15之外。一阻障金屬層ι7形成於每一導線柱16 的上端。一焊接凸塊18形成於該阻障金屬層17之上。 在此具有晶片級封裝結構的半導體裝置中，連接半導體 籲裝置兀件以及焊接凸塊的導線以極高的密度形成於半導體 基板之上。因此，其可降低半導體裝置的尺寸。 為了更進一步的降低半導體裝置的尺寸或厚度，半導體 基板的一厚度D需要被降低。因此，在目前的半導體裝置封 裝技術中，企圖藉由研磨該背面丨1B而使半導體裝置變的更 薄。 然而’半導體基板的厚度降低將增加缺陷的產生，例如 半導體基板的傷害或翹曲，並因此降低半導體裝置的生產良 鲁率。目前已有相關技術透過於半導體基板背面形成鈍化層的 方式，防止由於降低半導體基板厚度所產生的缺陷（例如， 日本專利早期公開第2002-23 1 854以及2002-270 720號專利 申請案）。 ° 然而’如果鈍化層形成於半導體基板的背面，該半導體 裝置的厚度將增加。因此，較難降低半導體裝置的厚度。 此外，形成鈍化層於半導體基板背面的另一個缺點為， 該鈍化層於形成半導體裝置的製程之中，常會部分從半導體 2001-71〇7-PF 6 200539298 基板上脫離。特別是，當該鈍化層的特性與（例如，硬度）與 該半導體基板相異時，該鈍化層於所謂的切割製程（dicing process)中，於半導體基板的裁切處會有部分鈍化層從半導 體基板上脫離。此鈍化層的部分脫落現象亦會降低半導體穿 置的生產良率。 ^ 【發明内容】 本發明即為了欲解決上述習知技術之問題，而提供之一 _種新而有效率的半導體裝置之製造方法，以及一種用於支撐 半導體基板的支樓結構。 本發明的一目的在於，提供之一種半導體裝置之製造方 法，以及一種用於支撐半導體基板的支撐結構，以降低具有 薄半導體基板的半導體裝置，或薄形半導體裝置的製造缺 陷。 根據本發明，其提供一種半導體裝置之製造方法，包括 一第一步驟，研磨一半導體基板的一第二表面，該第二表面 鲁相反於該半導體基板的一第一表面，該第一表面上設有複數 個半導體裝置元件；一第二步驟，在該第一步驟之後，將一 支撐結構黏著於該第二表面之上，以支撐該半導體基板；以 及一第二步驟，將該半導體基板脫離該支樓結構。 根據此製造半導體裝置的方法，薄形半導體裝置可以被 穩定的製造，並防止半導體基板受到傷害。 本發明之半導體裝置之製造方法較佳的更包括一切割 製程’於該第二步驟與該第三步驟之間切割該半導體基板。 2001-7107-PF 7 200539298 被穩…造一…

就另一方面而言，該黏著層202包括該第一黏著層20 2A 以及該第二黏著層20 2B，其可藉由一第一力從該支撐層201 2001-7107-PF 10 200539298 上脫離，該第一力大於使該半導體基板脫離所需要的一第二 力。特別是，該黏著層202於該第二黏著層2〇2β與該支撐 層201之間的介面脫離該支擇層2〇1。 此配置谷許该分離的黏著層2〇2以及該支撐層可分 別重複使用。例如，如果_衝擊施加於該支#結構2⑽之上 而使該支撐層201受到傷t，該黏著層2〇2可從受到損害的 支撐結構2G1脫離，而與—個新的支標層2〇1搭配使用。如 果，另一方面，該黏著層2〇2受到損傷或是失去黏性時，該 支撐層201可從該受損的黏著層2〇2脫離，而與一新的黏著 層2 0 2搭配使用。 “黏著層2 0 2較佳為該第一黏著層2 〇 2 a以及該第二黏 者層202B分別黏附於該基底層2〇2c的兩面，該基底層由pm 或是PEN所構成。#此，兮&戈μ ^错此該黏者層202可輕易的具有一上表 面及下表面’並彼此具有不同的黏著力，以貼負該半導 體基板以及該支撐層2 01。 該支擇層2 01較佳為具有 _體基板而防止該半導體基板鍾 一特定的硬度，以支撐該半導 區或傷害。 ，、較佳為具有耐熱以及抗化學反應的特性，以防止在半 導體裝置的製程(封裝製程)中遭受損傷、腐餘或餘刻。盆較 =具有相似於該半導體基板的物理特性，例如熱膨腹係數 等寺。 該支撐層2G1較佳㈣晶圓所製成，以滿足上述的要 求。特別時，當支撐結構200由石夕晶圓所製成時，不 對該支擇結構進行額外的處理，由於該支撑結構_與其所 2001-71〇7~pf 11 200539298 支撐的半導體基板具有相同的尺寸以及材質，並且其材料容 易取得。此外，可利用回收的矽晶圓而降低成本，由於回收 的矽晶圓經過蝕刻或是研磨的處理，其上形成有半導體裝置 元件以及薄膜，可作為支撐層2 〇 1。 若滿足上述要求，玻璃板或是陶瓷板亦可以作為支撐岸 201。 曰 以下說明應用本發明之實施例的支撐結構製作半導體 裝置的方法。 ~ [弟二實施例] 第3A至3P圖况明第二實施例中，製造一半導體 方法步驟。 弟如弟3A圖所顯示，提供一基板1〇卜該基板101 上设置有+導體元件。例如，該基板m由 如矽晶圓所製成。該基板1〇1且 ^ ιπ 土板 双上in具有一裝置面ι〇1 半導體裝置元件。A上玄#女 ，、上认有 K,„tJ . $ ，、上亦5又有一電極墊1〇2,由鋁或其他材 的-背面_之間的距：裝置。该裝置面101A以及相反 為700 _並介門的距離，例如，基板101的厚度dA大約 為"其亦可不以此厚度為限。 一純化層1 〇 3由氮化々 面101A，夕或其他材料所製成，覆蓋該裝置 面10IA，並讓該電極墊1〇 醯亞胺或其他㈣*開口路出。純化層104由聚 亦讓該電一 口 =成於該純化請之上，其 接著如第3β._顯示的，—金屬附著層1G5由金屬例

2001-7107-PF 15 200539298 接。 該樹知層113可選擇以堆積（iaminati〇n)樹脂薄膜的方 式形成。 接著，如第3M圖所顯示的，一焊接凸塊114形成於該 電鍵層111之上，並透過該電鍍層π丨耦接該導線柱丨丨〇。 接著，如第3Ν圖所顯示的，該支撐結構與基板i 〇丨黏 著’並貼附於切割帶11 5之上，切割帶11 5具有一切割架， 用於下述的切割製程之中。在第3N圖所顯示的步驟中，半 _導體裝置的產品（半導體晶片）僅剩下切割的步驟即可製作 完成’例如’將基板1 〇 1切割成晶片的步驟。意即，可得到 一半導體裝置（半導體晶片）1〇〇，其具有該基板1〇1、該裝置 面101A、該電極墊1〇2、該鈍化層ι〇3、該附著層ι〇5、該 晶種層106、該導線部1〇8、該導線柱u〇、該電鍍層U1、 該成形樹脂層113以及該焊接凸塊114。雖然第3N圖僅顯示 了 一半導體裝置1 〇 〇，其實有複數個半導體裝置丨〇 〇沿基板 1 01平面的方向陣列排列。 接者，如第30圖所顯示的，該基板ι〇1由切割技術所 裁切，而使該等半導體裝置1 00彼此分離。該切割機台較佳 為僅切割該成形樹脂層113至該基板101的位置，而不會切 割到該支撐結構2〇〇。 ' 弟3P圖所顯示的，該等半導體裝置（半導體晶 片）100藉由切割技術而相互分離，並藉由一切割夾持器將半 V體裝置100的背面101B脫離第-黏著層202A，而使得該 半‘體凌置100脫離該支撐結構2〇〇，而獲得完整的半導體
2001-7107-PF 16 200539298 裝置100。 藉此，該基板101可輕易的從該支撐結構200脫離，而 不會造成半導體裝置100厚度增加的問題。半導體裝置100 的厚度可因此降低。在習知技術中，由於基板以及黏著在基 板背面的純化層，在切割過程中—起被切割，缺陷例如微粒 剝離、純化層脫落以及碎屑等問題會時常發生。這些微粒剝 離或疋鈍化層脫落的問題會造成半導體裝置的形狀以及厚 度的變化。此實施例可防止這些問題的產生，並可確保半導 鲁體裝置具有相同的形狀，提高形狀的重現性。 在此實施例中，當該支撐結構200黏著該基板101之 後，可防止基板1〇1的破裂及翹曲現象，由於該基板1〇1係 由該支撐結構200支撐或夾持。 例如，該支撐結構200在第31圖移除背研磨帶}〗2的 步驟中、在第3J圖去除光阻層1〇9的步驟中、在第奵圖蝕 刻晶種層106以及附著層1〇5的步驟中以及在第3μ圖形成 •焊接凸塊114的步驟中防止基板1〇1的破裂以及翹曲。 特別是，在第3L圖中的形成成形樹脂的步驟中，其可 防止由於成形樹脂受熱彎曲，而在基板1〇1上層（包括成形 樹脂）產生的應力對基板1 〇 1所產生的傷害。 此外，在第30圖中的切割步驟中，切割動作可以被穩 定的操作，而防止基板i 〇丨發生傷害或碎屑等缺陷。 在將半導體裝置1〇〇脫離支撐結構2〇〇的步驟中，該半 導體裝置1〇〇可從該黏著層202分離而不需要使黏著層2〇2 從該支撐結構201分離，由於該第一黏著層2〇2A的黏著力 2001-7107-PF 17 200539298 小於第二黏著層202B的黏著力。 該黏著層202包括該第一黏著層202Α以及該第二黏著 層202Β，其可藉由一第一力從該支撐層201上脫離，該第一 力大於使該半導體基板脫離所需要的一第二力。特別是，該 黏著層202於該第二黏著層202Β與該支撐層201之間的介 面脫離該支撐層201。此設計容許該黏著層202以及該支撐 層2 01可分別重複使用。 由於本發明的支撐結構可重複使用，因此可降低基板 • 1 οι的保護成本。此外，由於該黏著層202以及該支撐層2〇1 可分別重複使用，可降低其維護成本。 雖然上述實施例揭露具有晶片級封裝（chip size package，CSP)結構的半導體裝置，其並未限制本發明。本 發明可以應用於其他以背研磨製程降低基板厚度的半導體 裝置之中，藉此可防止基板破裂或翹曲的產生，提高半導體 裝置的良率，並容許基板脫離支撐結構，降低半導體裝置的 厚度。 上，然其並非
