Abstract
提供具有電路之晶圓與支持基板之臨時接著容易,且對TSV形成步驟、晶圓背面配線步驟之步驟適合性高,進而剝離亦容易,可提高薄型晶圓之生產性的晶圓加工用臨時接著材料、晶圓加工體及使用此等之薄型晶圓之製造方法。
一種晶圓加工用臨時接著材料,其係用以將表面具有電路,且欲加工背面之晶圓與支持基板暫時接著之晶圓加工用臨時接著材料,其係具備能夠以可剝離的方式接著於晶圓之表面的由熱可塑性聚矽氧改質苯乙烯系彈性體層(A)所構成之第一臨時接著層、與層合於第一臨時接著層,能夠以可剝離的方式接著於支持基板的由熱硬化性聚合物層(B)所構成之第二臨時接著層者。
Description
本發明係關於可有效果地得到薄型晶圓之晶圓加工用臨時接著材料、晶圓加工體及使用此等之薄型晶圓之製造方法。
為了實現更加高密度、大容量化、高速化、低消耗電力化,3次元之半導體構裝正成為必須。3次元半導體構裝技術,係指將1個半導體晶片薄型化,進一步將之藉由矽貫通電極(TSV;through silicon via)結線,同時層合為多層之半導體製作技術。為了將之實現,必須進行將形成有半導體電路之基板藉由非電路形成面(亦稱為「背面」)磨削而薄型化,且進一步於背面形成包含TSV之電極的步驟。
以往,於矽基板之背面磨削步驟中,係於磨削面之相反側貼上保護膠帶,以防止磨削時之晶圓破損。但是,該膠帶係於基材使用有機樹脂薄膜,其具有柔軟性,但相對地強度或耐熱性不充分,不適於進行TSV形
成步驟或於背面之配線層形成步驟。
因而,提出藉由將半導體基板透過接著層接合於矽、玻璃等之支持體(支持基板),而可充分耐受背面磨削、TSV或背面電極形成之步驟的系統。此時重要者為,將基板接合於支持體時的接著層。此係必須可將基板無間隙地接合於支持體,且可耐受其後步驟程度的充分耐久性,且必須進一步於最後可將薄型晶圓由支持體簡便地剝離。如此地,由於最後會剝離,因而本說明書中,將該接著層稱為臨時接著層。
迄今作為公知之臨時接著層與其剝離方法,提出有將聚矽氧黏著劑使用於臨時接著層之技術(專利文獻1)、及將熱熔融性之烴系化合物使用於接著材,於加熱熔融狀態進行接合/剝離之技術(專利文獻2)。前者係將基板使用加成硬化型之聚矽氧黏著劑接合於支持體,於剝離時係將聚矽氧樹脂浸漬於會溶解、或分解之藥劑而將基板由支持體分離者。因此剝離需要非常長時間,對實際上之製造製程的應用困難。又,後者之技術僅以加熱來控制因此為簡便,但相對地於超過200℃之高溫下的熱安定性不充分,因此適用範圍窄。
又,亦提出有對含有光吸收性物質之接著劑照射高強度之光,分解臨時接著層,藉以由支持體剝離薄型晶圓之技術(專利文獻3)或者藉由含有光吸收性物質之接著劑與含有苯乙烯系彈性體之接著劑的組合照射高強度之光後,藉由溶劑使彈性體膨潤、剝離之技術。(專利
文獻4)。但是,前者、後者均必須要雷射等之高價格裝置,且每1枚基板之處理時間增長,特別是後者因為係溶劑處理,因此係有處理時間更加長之問題。

本發明係有鑑於上述問題點而為者,其目的為提供具有電路之晶圓與支持基板之臨時接著容易,且對TSV形成步驟、晶圓背面配線步驟之步驟適合性高,進而剝離亦容易,可提高薄型晶圓之生產性的晶圓加工用臨時接著材料、晶圓加工體及使用此等之薄型晶圓之製造方法。
為了達成上述目的,本發明中提供一種晶圓加工用臨時接著材料,其係用以將表面具有電路,且欲加工背面之晶圓與支持基板暫時接著之晶圓加工用臨時接著
材料,其特徵為具備能夠以可剝離的方式接著於前述晶圓之表面之由熱可塑性聚矽氧改質苯乙烯系彈性體層(A)所構成之第一臨時接著層、與層合於該第一臨時接著層,能夠以可剝離的方式接著於前述支持基板之由熱硬化性聚合物層(B)所構成之第二臨時接著層。
若為如此之晶圓加工用臨時接著材料(以下亦記載為臨時接著材料),則具有電路之晶圓與支持基板之臨時接著及剝離為容易。又,藉由透過由該臨時接著材料所構成之臨時接著層而將晶圓與支持基板暫時接著(臨時接著),可使對TSV形成步驟、晶圓背面配線步驟之步驟適合性提高。又,對CVD(化學氣相成長)等之熱製程之耐性亦成為良好。特別地,即使為如具有電路之晶圓般的高階差基板,亦可形成均勻膜厚的臨時接著層。藉此可提高薄型晶圓之生產性。
又,較佳為前述熱可塑性聚矽氧改質苯乙烯系彈性體,係聚矽氧改質嵌段共聚物,且該共聚物中之苯乙烯單位的含量為10質量%以上、40質量%以下之範圍。

(式中,R4、R5係分別獨立地為碳數1~10之取代或非取代之一價烴基;Me為甲基,a、b分別為0或正數,但a+b為1以上之整數)]。
若為包含如此之聚矽氧單位的第一臨時接著層,則藉由調節該聚矽氧單位之含量,可控制與第二臨時接著層之接著力。
又,前述熱可塑性聚矽氧改質苯乙烯系彈性體層(A)之25mm寬度之試驗片的180°剝除剝離力,較佳為2gf以上、50gf以下。
若為具有如此之剝除剝離力的熱可塑性聚矽氧改質苯乙烯系彈性體層(A)(以下亦記載為聚合物層(A)),則晶圓磨削時並無產生晶圓偏移之虞,剝離容易,故較佳。
又,前述熱硬化性聚合物層(B),較佳係相對於具有下述通式(3)表示之重複單位的重量平均分子量3,000~500,000之含有矽氧烷鍵之聚合物100質量份而言,含有0.1~50質量份之作為交聯劑的由經甲醛或甲醛-醇改質之胺基縮合物、三聚氰胺樹脂、脲樹脂、1分子中平均具有2個以上之羥甲基或烷氧基羥甲基的酚化合物、及1分子中平均具有2個以上之環氧基的環氧化合物中選出之任1種以上的組成物之硬化物層。

(式中,Z為由
之任一者中選出之2價有機基,n為0或1。又,R10、R11各自為碳原子數1~4之烷基或烷氧基,相互可相同亦可相異。k為0、1、2之任一者)]。
若為如此之熱硬化性聚合物層(B)(以下亦記載為聚合物層(B)),則成為耐熱性更加優良者,又,會成為膜厚均勻性佳之臨時接著層,故較佳。
又,前述熱硬化性聚合物層(B),較佳係相對於具有下述通式(5)表示之重複單位的重量平均分子量3,000~500,000之含有矽氧烷鍵之聚合物100質量份而言,含有0.1~50質量份之作為交聯劑的由1分子中平均具有2個以上之酚基的酚化合物、及1分子中平均具有2個以上之環氧基的環氧化合物中選出之任1種以上的組成物之硬化物層。
[式中,R6~R9表示可相同亦可相異的碳原子數1~8之1價烴基。又,m為1~100之整數,B為正數、A為0或正數。進一步地,Y為下述通式(6)表示之2價有機基。
(式中,V為由
之任一者中選出之2價有機基,p為0或1。又,R12、R13各自為碳原子數1~4之烷基或烷氧基,相互可相同亦可相異。h為0、1、2之任一者)]。
若為如此之熱硬化性聚合物層(B),則成為耐熱性更加優良者,又,會成為膜厚均勻性佳之臨時接著層,故較佳。
進一步地,本發明中,提供一種晶圓加工體,其係於支持基板上形成由上述本發明之晶圓加工用臨時接著材料所構成之臨時接著層,且於該臨時接著層上層合表面具有電路,且欲加工背面之晶圓而成的晶圓加工體,其特徵為,以可剝離的方式將前述第一臨時接著層接著於前述晶圓之表面,且以可剝離的方式將前述第二臨時接著層接著於前述支持基板者。
若為如此之晶圓加工體,則具有電路之晶圓與支持基板的臨時接著及剝離則為容易。又,可使對TSV形成步驟、晶圓背面配線步驟之步驟適合性提高。藉此,可提高薄型晶圓之生產性。
進一步地,本發明中,提供一種薄型晶圓之製造方法,其特徵為具有將表面具有電路,且欲加工背面之晶圓之前述表面,隔著由上述本發明之晶圓加工用臨時接著材料所構成之臨時接著層,接合於支持基板之步驟、將前述熱硬化性聚合物層(B)予以熱硬化之步驟、將與前述支持基板接合後之晶圓之背面予以磨削或研磨之步驟、對經前述磨削或研磨之晶圓的背面施以加工之步驟、與將經施以前述加工之晶圓由前述支持基板剝離之步驟。
若為如此之薄型晶圓之製造方法,則藉由將本發明中由2層系所構成之臨時接著層,使用於晶圓與支持基板之接合,則可容易地製造具有貫通電極構造、或凸塊連接構造之薄型晶圓。
又,前述剝離之步驟後,較佳為進行將前述經剝離之晶圓表面所殘存之前述臨時接著層予以去除之步驟。
若為如此之薄型晶圓之製造方法,則於剝離
之步驟後,即使於晶圓表面殘存有臨時接著層的情況,亦可得到完全去除臨時接著層之晶圓。
又,較佳為於前述接合之步驟中,貼合於前述晶圓之表面形成有前述第一臨時接著層者、與於前述支持基板上形成有前述第二臨時接著層者;或貼合於前述晶圓之表面形成前述第一臨時接著層,且於該第一臨時接著層上形成有前述第二臨時接著層者、與前述支持基板。
若為如此之薄型晶圓之製造方法,則前者的情況時,與晶圓之表面狀態無關地,可於支持基板上以旋轉塗佈法等形成第二臨時接著層,可實施貼合。又,後者的情況時,於以旋轉塗佈法等形成第二臨時接著層的情況時,能夠於支持基板側之面以無第二臨時接著層之殘渣的方式來進行處理,因此於其後之步驟中並無殘渣剝落之虞。
本發明之臨時接著材料,即使對具有電路之晶圓(具有階差之晶圓),亦可形成膜厚均勻性高之臨時接著層,因為此膜厚均勻性,故可容易地得到50μm以下之均勻的薄型晶圓。進一步地,因為於第一臨時接著層使用了經聚矽氧改質之熱可塑性苯乙烯系彈性體,故薄型晶圓製作後,可容易地將晶圓由支持基板剝離。因此,可不對容易破裂之薄型晶圓造成損傷地進行操作,可容易地製造薄型晶圓。又,將剝離後之支持基板洗淨後亦可再利
用,因此可減低製造成本。

以下,具體說明本發明之實施形態,但本發明不限定於此等。
圖1係顯示本發明之晶圓加工體之一例的截面圖。如圖1所示,本發明之晶圓加工體10,具備表面具有電路,且欲加工背面之晶圓1、於晶圓1加工時支持晶圓1之支持基板2、與存在於此等晶圓1與支持基板2之間的晶圓加工用臨時接著材料(臨時接著層)3,該臨時接著層3,係由熱可塑性聚矽氧改質苯乙烯系彈性體層(A)(第一臨時接著層)、與熱硬化性聚合物層(B)(第二臨時接著層)所構成,第一臨時接著層係以可剝離的方式接著於晶圓1表面,層合於該第一臨時接著層上之第二臨時接著層係以可剝離的方式接著於支持基板2者。
又,本發明之晶圓加工用臨時接著材料,係由上述聚合物層(A)及聚合物層(B)之層合體構成者。
以下更詳細說明本發明,但本發明不限定於此等。
本發明中之第一臨時接著層,係包含熱可塑性聚矽氧改質苯乙烯系彈性體之層。熱可塑性聚矽氧改質苯乙烯系彈性體(以下亦記載為彈性體(A)),例如係含有聚矽氧單位與苯乙烯單位之彈性體。
彈性體(A)例如可使苯乙烯系彈性體與矽氧
烷反應而得到。此時,苯乙烯系彈性體,可為均聚物、亦可為使苯乙烯與具有乙烯基等之烯基之單體共聚合之共聚物。共聚物等之共聚物,可為無規共聚物、亦可為嵌段共聚物。具有烯基之單體的具體例子,可列舉丁二烯或異戊二烯等之二烯化合物。再者,作為烯基,係碳數2~10、較佳為3~6者為佳。
例如,苯乙烯系彈性體,若為苯乙烯與二烯化合物之共聚物,則可對此共聚物內殘存之乙烯基,使矽氧烷進行反應,而得到彈性體(A)。
苯乙烯系彈性體之具體例子,可列舉含有烯基之苯乙烯系彈性體(A-1)(以下亦記載為彈性體(A-1))。該彈性體(A-1)只要係包含烯基與苯乙烯單位之彈性體即可,由耐熱性觀點而言,於彈性體之中尤以兩端為苯乙烯之嵌段共聚物較佳。又,聚合物中之苯乙烯單位的含量較佳為10質量%以上、40質量%以下之範圍者、更佳為20質量%以上、35質量%以下者。若為如此之苯乙烯含量,則所得之彈性體(A)的溶解性良好、且剝離後之洗淨性成為良好,故較佳。
彈性體(A-1)之具體例子,可列舉Kraton D[苯乙烯-丁二烯-苯乙烯嵌段共聚物未氫化物:SBS Kraton Polymers Japan股份有限公司製]、Hybrar 5125、5127[苯乙烯-異戊二烯-苯乙烯嵌段共聚物未氫化物:SIS Kuraray股份有限公司製]等之苯乙烯嵌段共聚物。
再者,苯乙烯系彈性體之重量平均分子量之
範圍,較佳為5,000~200,000左右、更佳為10,000~100,000左右。大於5,000時,所得之彈性體(A)的耐熱性提高、少於200,000時,所得之彈性體(A)容易溶解於烴系溶劑中,且可容易且迅速地去除。
此處,彈性體(A)中之聚矽氧單位,較佳為以下述通式(1)表示者。
[式中,R1、R2、R3係分別獨立地為碳數1~10之取代或非取代之一價烴基,S、T、U為單鍵或下述通式(2)表示之二價矽氧烷構造,但S、T、U之至少一者為下述通式(2)表示之二價矽氧烷構造。
(式中,R4、R5係分別獨立地為碳數1~10之取代或非取代之一價烴基,Me為甲基,a、b分別為0或正數,但a+b為1以上之整數。較佳為a+b=1~100之整數)]。
具有上述通式(1)表示之聚矽氧單位的彈性體(A)之製造方法並無特殊限定,可列舉例如將下述通式(7)表示之1分子內含有1個SiH基之有機氫聚矽氧烷
[式中,R1、R2、R3係分別獨立地為碳數1~10之取代或非取代之一價烴基,S、T、U為單鍵或下述通式(8)表示之二價矽氧烷構造,但S、T、U之至少一者為下述通式(8)表示之二價矽氧烷構造。
(式中,R4、R5係分別獨立地為碳數1~10之取代或非取代之一價烴基,Me為甲基,a、b分別為0或正數,但a+b為1以上之整數)]
、與含有烯基之苯乙烯系彈性體(A-1),在鉑族金屬系觸媒之存在下進行氫矽烷基化反應而得到之方法。此時,相對於彈性體(A-1)之總烯基而言,上述通式(7)表示之矽氧烷之總SiH基較佳成為0.1~1.0倍之量。
R1~R5為碳數1~10之取代或非取代之一價烴基,具體例子可列舉甲基、乙基、丙基、丁基等之烷基;或此等基之氫原子的一部分或全部被鹵素原子等取代之基。
彈性體(A-1)與上述通式(7)表示之矽氧烷之反應,例如,可藉由將彈性體(A-1)溶解於有機溶劑,添加氫矽烷基化觸媒之鉑系金屬觸媒後,一邊於50
~150℃加熱,同時滴下上述通式(7)表示之矽氧烷,以得到熱可塑性聚矽氧改質苯乙烯系彈性體(A)。
鉑族金屬系觸媒係用以促進烯基與SiH基之氫矽烷基化加成反應的觸媒,該加成反應觸媒,可列舉鉑黑、氯化鉑(IV)、氯化鉑酸、氯化鉑酸與一元醇之反應物、氯化鉑酸與烯烴類之錯合物、鉑雙乙醯乙酸鹽等之鉑系觸媒;鈀系觸媒、銠系觸媒等之鉑族金屬觸媒。再者,該加成反應觸媒之摻合量可為觸媒量,通常以鉑族金屬計,相對於上述通式(7)表示之矽氧烷之重量而言,較佳為摻合1~800ppm、特別是2~300ppm左右。
加成反應後之具有上述通式(1)表示之聚矽氧單位的彈性體(A)之聚矽氧含有率,以含有烯基之苯乙烯系彈性體(A-1)為100質量份時,上述通式(7)表示之矽氧烷,較佳為1質量份至30質量份、更佳為3質量份至20質量份。矽氧烷之量若為1質量份以上,則作為第一臨時接著層使用時,剝離性優良。若為30質量份以下,則亦無耐熱性降低的情事。
又,熱可塑性聚矽氧改質苯乙烯系彈性體,較佳為聚矽氧改質嵌段共聚物。
聚矽氧改質嵌段共聚物,例如可使上述苯乙烯嵌段共聚物與矽氧烷反應而得到。例如,具有上述通式(1)表示之聚矽氧單位的彈性體(A)之製造方法中,彈性體(A-1)為苯乙烯嵌段共聚物時,可得到具有上述通式(1)表示之聚矽氧單位的聚矽氧改質嵌段共聚物,作
為彈性體(A)。
又,聚矽氧改質嵌段共聚物中之苯乙烯單位含量較佳為10質量%以上、40質量%以下之範圍。若為如此之苯乙烯含量,則對烴系溶劑之溶解性成為良好,剝離後之洗淨性成為良好。再者,聚矽氧改質嵌段共聚物中之苯乙烯單位含量,可藉由調節原料之苯乙烯嵌段共聚物中的苯乙烯單位含量、或調節苯乙烯嵌段共聚物與矽氧烷之摻合比,而成為上述範圍內。

本發明之薄型晶圓之製造方法,其特徵為使用由熱可塑性聚矽氧改質苯乙烯系彈性體層(A)與熱硬化性聚合物層(B)之2層所構成之臨時接著層,作為具有半導體電路等之晶圓與支持基板之接著層。藉由本發明之製造方法而得之薄型晶圓的厚度,典型而言為5~300μm、更典型而言為10~100μm。
步驟(a),係將表面具有電路,且欲加工背面之晶圓,亦即將具有電路形成面及電路非形成面之附電路晶圓的表面,透過由上述本發明之晶圓加工用臨時接著材料所構成之臨時接著層,接合於支持基板之步驟。
該步驟(a)中,較佳為(1)將於晶圓表面形成有第一臨時接著層(聚合物層(A))者、與於支持
基板上形成有第二臨時接著層(聚合物層(B))者予以貼合或(2)將於晶圓表面形成第一臨時接著層,且於該第一臨時接著層上形成有第二臨時接著層者、與支持基板予以貼合。此時,較佳為於真空下實施貼合。
藉此,(1)的情況時,與晶圓之表面狀態無關地,可於支持基板上以旋轉塗佈法等形成第二臨時接著層,可實施貼合。又,(2)的情況時,以旋轉塗佈法等形成第二臨時接著層時,能夠於支持基板側之面以無第二臨時接著層之殘渣的方式來進行處理,因此於其後之步驟中並無殘渣剝落之虞。
具有電路形成面及電路非形成面之晶圓,係一面為電路形成面、另一面為電路非形成面之晶圓。可適用本發明之晶圓,通常係半導體晶圓。該半導體晶圓之例子,不僅矽晶圓,可列舉鍺晶圓、鎵-砷晶圓、鎵-磷晶圓、鎵-砷-鋁晶圓等。該晶圓之厚度並無特殊限制,典型而言為600~800μm、更典型而言為625~775μm。
支持基板,可使用矽晶圓或玻璃板、石英晶圓等之基板,並無任何限制。本發明中,並無需要通過支持基板對臨時接著層照射放射能量線,支持基板亦可為不具有光線透過性者。
臨時接著層(聚合物層)(A)、(B)亦可分別以薄膜的形式形成於晶圓或支持基板上,或者可將各自之溶液藉由旋轉塗佈等之方法形成於晶圓或支持基板上。此時,旋轉塗佈後,係依該溶劑之揮發條件,於80
~200℃之溫度預先進行預烘烤後供使用。
形成有臨時接著層(A)、(B)之晶圓及支持基板,係透過(A)層(聚合物層(A))與(B)層(聚合物層(B)),形成作為經接合之基板。此時,較佳為於40~200℃、更佳為60~180℃之溫度區域,於該溫度於減壓下,將該基板均勻地壓接,藉以形成晶圓與支持基板接合之晶圓加工體(層合體基板)。
晶圓貼合裝置,可列舉市售之晶圓接合裝置,例如EVG公司之EVG520IS、850TB、SUSS公司之XBC300等。
步驟(b),係使熱硬化性聚合物層(B)熱硬化之步驟。形成上述晶圓加工體(層合體基板)後,藉由於120~220℃、較佳為150~200℃加熱10分~4小時、較佳為30分~2小時,來進行聚合物層(B)之硬化。
步驟(c),係將與支持基板接合之晶圓的背面予以磨削或研磨之步驟,亦即,將於步驟(a)中貼合所得之晶圓加工體的晶圓背面側予以磨削或研磨,使該晶圓之厚度變薄之步驟。晶圓背面之磨削加工的方式並無特殊限制,係採用公知之磨削方式。磨削較佳係一邊於砥石(金剛石等)上加水進行冷卻同時對晶圓加工體之非電路形成
面進行磨削。將晶圓背面磨削加工之裝置,可列舉例如(股)Disco製DAG-810(商品名)等。又,亦可將晶圓背面側進行CMP研磨。
步驟(d),係對經磨削或研磨之晶圓背面施以加工之步驟。特別地,係將經背面磨削而薄型化的晶圓加工體之背面施以加工之步驟。該步驟中係包含於晶圓等級使用之各種製程。例如可列舉電極形成、金屬配線形成、保護膜形成等。更具體而言,可列舉用以形成電極等之金屬濺鍍、蝕刻金屬濺鍍層之濕蝕刻、用以作為金屬配線形成之遮罩的阻劑之塗佈、曝光、及以顯影形成圖型、阻劑之剝離、乾蝕刻、金屬鍍層之形成、用以形成TSV之矽蝕刻、矽表面之氧化膜形成等以往公知之製程。
步驟(e)係將於步驟(d)中實施過加工之晶圓由支持基板剝離之步驟,亦即,對經薄型化之晶圓施以各種加工後,於切割前將晶圓由支持基板剝離之步驟。該剝離步驟一般係於室溫至60℃左右的較低溫的條件下實施,可列舉將晶圓加工體之晶圓或支持基板之一方預先固定為水平,將另一方自水平方向賦予一定角度拉起的方法、及於經磨削之晶圓的磨削面貼上保護薄膜,將晶圓與保護薄膜以剝除的方式由晶圓加工體剝離之方法等。本發明中,可
適用於此等剝離方法之任意者。此等剝離方法通常於室溫實施。
又,(e)將實施過加工之晶圓由支持基板剝離之步驟,較佳為包含(f)將切割膠帶接著於實施過加工之晶圓的晶圓面(背面)之步驟、(g)將切割膠帶面真空吸附於吸附面之步驟、與(h)以吸附面之溫度為10℃至100℃之溫度範圍,將支持基板由實施過加工之晶圓以剝除方式剝離之步驟。藉由如此地進行,可將支持基板容易地由實施過加工之晶圓剝離,又,可容易進行其後之切割步驟。
又,(e)將實施過加工之晶圓由支持基板剝離之步驟後,較佳為進行(i)將經剝離之晶圓表面所殘存之臨時接著層去除之步驟。
於藉由步驟(e)由支持基板所剝離之晶圓的電路形成面,會有臨時接著層、特別是臨時接著層(A)一部分殘存的情況。此時,較佳為實施步驟(i)。臨時接著層(A)等之去除,例如可藉由洗淨晶圓來進行。
步驟(i)中,只要係會溶解臨時接著層中之(A)層即聚矽氧改質苯乙烯系彈性體的洗淨液,則均可使用,具體而言可列舉癸烷、異壬烷、p-薄荷烷、蒎烯、檸檬烯等。此等之溶劑可1種單獨亦可組合2種以上使用。又,不易去除時,亦可於上述溶劑中添加鹼類、酸
類。鹼類之例子可使用乙醇胺、二乙醇膠、三乙醇胺、三乙基胺、氨等之胺類;氫氧化四甲基銨等之銨鹽類。酸類可使用乙酸、草酸、苯磺酸、十二烷基苯磺酸等之有機酸。鹼類、酸類之添加量,以洗淨液中濃度計,係0.01~10質量%、較佳為0.1~5質量%。又,為了提高殘存物之去除性,亦可添加既存之界面活性劑。洗淨方法可為使用上述液體以槳葉進行洗淨之方法、以噴霧進行的洗淨方法、浸漬於洗淨液槽之方法。溫度係10~80℃、較佳為15~65℃為宜,若有必要,亦能夠以此等溶解液溶解(A)層後,最終以水洗或以醇進行潤洗,並乾燥處理,來得到薄型晶圓。

以研磨器(DISCO製、DAG810)使用金剛石砥石進行矽晶圓之背面磨削。研磨至最終基板厚50μm之後,以光學顯微鏡(100倍)調查有無龜裂、剝離等之異常。未產生異常時評估為良好,以「○」表示、產生異常時評估為不良,以「×」表示。
將背面磨削矽晶圓後之層合體置入於減壓下之180℃烘箱30分鐘或2小時後,調查有無外觀異常。未產生外觀異常時評估為良好,以「○」表示,僅外周剝離時以「△」表示,產生外觀異常(整面剝離)時評估為不良,以「×」表示。
基板之剝離性係由以下方法評估。首先於耐熱性試驗結束後的晶圓加工體之薄型化為50μm之晶圓側,使用切割框貼上切割膠帶,將此切割膠帶面藉由真空吸附設置於吸附板。之後,於室溫以鑷子將支持基板的1點拉起,藉此將支持基板剝離。50μm之晶圓可無破裂地剝離時以
「○」表示,支持基板破裂但可剝離時以「△」表示,完全無法剝離時評估為不良,以「×」表示。
將上述剝離性試驗結束後之透過切割膠帶安裝於切割框之200mm晶圓(經暴露於耐熱性試驗條件者),以接著層為上方設置於旋轉塗佈器,噴霧p-薄荷烷5分鐘作為洗淨溶劑,之後一邊使晶圓旋轉,同時噴霧異丙基醇(IPA)進行潤洗。之後,觀察外觀,目視檢查有無殘存之接著材樹脂。未觀察到樹脂殘存者評估為良好,以「○」表示,觀察到樹脂殘存者評估為不良,以「×」表示。
於作為支持基板之矽晶圓上,以與各自之實施例及比較例中製作者相同條件,形成聚合物層(B),於其上形成聚合物層(A)後,貼附5條150mm長×25mm寬之聚醯亞胺膠帶,將未貼有膠帶的部分之臨時接著層予以去除。使用島津製作所公司之AUTOGRAPH(AG-1),由膠帶一端180°剝離而剝除120mm,將此時的施力之平均(120mm行程×5次),作為該臨時接著層之剝離力。
基於評估結果,綜合評估於薄型晶圓之製造中可否使
用,判斷係為◎:優、○:良、×:不可。
如表1所示,滿足本發明之要件的實施例1~7中,可知臨時接著及剝離容易。特別地,實施例1~5,係聚矽氧含量為1質量份至30質量份之範圍內,且剝除剝離力為2gf以上、50gf以下之範圍內,因此耐熱性及剝
離性更優良。另一方面,(A)層不滿足本發明之要件的比較例1中,剝離性試驗中完全無法進行晶圓之剝離。
再者,本發明不限定於上述實施形態。上述實施形態係為例示,只要與本發明之申請專利範圍記載之技術思想具有實質上相同之構成,且發揮同樣之作用效果者,均包含於本發明之技術範圍中。
