,CH2〇CH2CH2CH2Si(〇CH3); CH2〇CH2CH2CH2Si(〇CH3)3 組合物中,成分(D)之含量並無限制,只要其量足以使組合 物具有滿意之黏著力即可,但較好每重量份之成分(A) 為0.01至20重量份,且更好為0.1至10重量份。此係因為當 成份(D)之含量低於上述範圍之下限時,所得組合物之黏 性,且當含量超過上述範圍之上限時,會對所得硬化產物 之機械強度產生負面作用,但仍不影響所得組合物之黏性。 成分(E)為促進組合物中之硬化反應之氫矽烷化觸媒。成 分(E)之實例包含鉑觸媒、鍺觸媒及鈀觸媒,且最佳者為鉑 觸媒,因為其可明顯的促進硬化反應。此鉑觸媒之實例包 含細微鉑粉、鉑黑、鉑支撐之細微氧化矽粉末、鉑支撐之 活性碳、氣銘酸、氯顧酸之醇溶液、銘-稀烴錯合物、顧烯 基矽氧烷錯合物及其中此等鉑觸媒均分散或包封於丙烯酸 系樹脂中之樹脂粉末、聚碳酸酯樹脂、矽酮樹脂、聚醯胺 樹脂或其他該熱塑性樹脂。 86646 -15- 1293191 組合物中,成分⑻之含量並沒有限制,只要其量足以促 進上述組合物之硬化反應即可;例如,#使關觸媒作為 成分(E)時,觸媒中始金屬之量相對於組合物為〇〇1至1〇〇〇 ppm重T早位,且更好為G.1至5GGppm。此係因為當成份⑻ 之含量低於上述範圍之下限時,所得組合物之硬化反應會 極慢,且當含量超過上述範圍之上限時,所得硬化產物; 有變色或冑於其他不必要變化之危&,但I化速度仍不受 影響。 為凋整硬化速度,上述組合物較好含有硬化起始劑如弘 甲基-1-丁決'3-醇、3,5·二甲基小己玦|醇、苯基丁炔醇, 或另一種該燒炔醇;3-甲基戊缔+块、3,5_二甲基冬己 缔-1-炔或另一種該缔·炔化合物;四甲基nn 四乙烯基環四碎氧燒、1,3,5,7_四甲基],3,5,7四己烯基環 四矽氧烷或另一種含有缔基之該有機矽氧烷;以下式表示 之有機矽烷 CH3Si [OC(CH3)2CeCH]3 或以下式表示之有機碎燒 CH3(CH2=CH)Si[OC(CH3)2C=CH]2 或以下式表示之有機碎燒 (CH3)3Si [OC(CH3)2C 三 CH] 或另一種含炔氧基之該等有機矽烷;或苯并三唑。 組合物中,硬化起始劑之含量並無限制,但每1〇〇重量份 之成分(A)較好為0.00001至5重量份。此係因為所得組合物 之硬化速度不易調整,且當硬化起始劑之含量低於上述範 86646 -16 - 1293191 圍之下限時,會削弱其處理操作,當含量超過上述範園之 上限時,所得組合物會有硬化不足之危險。 組合物以含染料、顏料、賦予耐熱性之藥劑、難燃劑及 通常可與可硬化矽酮組合物與混合之其他添加劑,只要其 他選用之成分不犧牲本發明之目的即可。 為調整任何可氫矽烷化硬化之矽酮組合物之硬化速度, 以製造上述之板,因此可能例如選擇成分(C)之種類、選擇 成分(E)之種類,調整其含量、選擇硬化起始劑之種類,及 調整其含量。尤其,當使用分子鏈終端具有與矽接合之氫 原子之有機考矽酮作為組合物中之成分(C)時,其反應性高 於由具有由分子鏈侧鏈中之與矽接合氫原子之有機聚矽酮 所得者,且所得組合物因此可快速硬化。而且組合物中, 成分(E)含量較大,則所得組合物硬化更快速。而且,硬化 起始劑之含量較大則所得組合物之硬化會較慢。因此,可 製備具有不同硬化速度之似黏土可硬化矽酮組合物。此等 似黏土可硬化矽酮組合物之硬化速度可例如在使用震盪硫 化試驗機進行之硫化試驗(JIS K 6300之說明)中,在相同溫 度條件(例如130°C,150°C)下測量之其90%硫化時間(te(90)) 確定。 圖1中’保護膜3及4穩固的接合於板之二表面上。使用保 護膜係視情況,但保護膜較好穩固的接合於板之一面或兩 面’因為其可避免板之前表面沉積之粉塵。當使用板時, 可剝離保護膜。保護膜3及4可相同或不同。該保護膜之實 例尤其包含包括聚對酞酸乙二酯樹脂(PET)、聚丙婦樹脂 86646 -17- 1293191 (PP)、聚醚颯樹脂(PES)、三乙酸酯纖維素樹脂(TAC)及其 他適用之纖維素樹脂,以及聚亞醯胺樹脂、聚酯樹脂、聚 醚樹脂、環氧樹脂、酚樹脂、聚醯胺樹脂及其他該有機樹 脂;及其中包括此等有機樹脂之薄膜表面覆蓋氟碳樹脂或 另一種有機樹脂之薄膜。 製備板之方法並無限制,且實例包含將其中含似黏土可 硬化矽酮組合物之甲苯、庚烷或另一種該有機溶劑之溶液 塗饰於保護膜上’硬化速度與前述組合物不同之似黏土可 硬化矽酮組合物之有機溶劑溶液同樣塗佈於另一薄膜上, 接著將似黏土之可硬化矽酮組合物積層在一起之方法;其 中將似黏土可硬化矽酮組合物之有機溶劑溶液塗佈於保護 膜上且另塗佈硬化速度與上述組合物不同之似黏土可硬 化矽酮組合物之有機溶劑溶液之方法;及其中之保護膜藉 由壓延覆蓋以組合物,且在塗佈硬化速度與前述組合物不 同之似黏土可硬化矽酮組合物之有機溶劑溶液之方法。 本發明另一種以矽酮為基質之黏著板示於圖2中。該板在 其一表面上具有硬化之硬化矽層5及另一表面上之似黏土 惑可硬化矽酮組合物層6。硬化層5之厚度並沒有限制,但 較好為100微米或更薄,更好為1至100微米,且最好為1至 、微米組合物層6之厚度亦沒有限制,但較好為i 〇〇微米 或更薄,更好為1至1〇〇微米,且最好為丄至%微米。板之厚 度亦沒有限制,但較妤為100微米或更薄。 、硬化層5係藉由例如使可氫矽烷化硬化之矽酮組合物、可 縮合硬化切合物、可藉由包含有機過氧化物之游離 86646 -18- 1293191 基反應硬化之矽酮組合物、可藉由高能輻射硬化之矽酮組 合物或另一種可硬化之矽酮組合物硬化形成,但較好係藉 由使可氫矽烷化硬化之矽酮組合物硬化形成。硬化產物: 性質並沒有限制,但較好為彈性體性質,且最好為橡膠性 質。 ’ 孩板中,似黏土可硬化矽酮組合物以JIS κ 6249說明之塑 性數並沒有限制,但較好為100至8〇〇,更好為1〇〇至7⑼, 且最好為100至500。依據Jls κ 6249之說明,該塑性數為當 藉由平行板塑性计((William’s Plastimeter))施加 49士0.05 Ν 負荷於樣品{圓柱體標的(直徑16毫米,高度1〇毫米),體積 為2±0·02立方公分(cin3)}分鐘後之值。 藉由使似黏土可硬化矽酮組合物製備之硬化矽酮組合物 之性質並沒有限制,但較好為彈性體性質,且最好為橡膠 性質。該可硬化矽酮組合物之硬化結構並沒有限制,且其 貫例包含可氲碎規化硬化之碎酮組合物、可縮合硬化之珍 酉同組6物、可藉由包含有機過氧化物游離基反應硬化之秒 酮組合物即可藉由高能輻射硬化之可硬化秒酮組合物,但 取佳者為可氳秒燒化硬化之秒酮組合物。可氫秒垸化硬化 之矽酮組合物係如前述。 圖2中,保護膜7及8係穩固的接合於以矽酮為基質之黏著 板兩面上。使用此等保護膜為視情況使用,但保護膜較好 穩固的接合於板之一面或兩面上,因為其可避免板之前表 面沉積之灰塵。當使用板時需剝離保護膜。保護膜7及8之 保護膜為相同或不同。該保護膜之實例包含與先前所述相 86646 •19- 1293191 同之膜。 製備黏著板之方法並沒有限制,且實例包含將其中含似 黏土可硬化矽酮組合物之甲苯、庚烷或另一種該有機溶劑 之溶液塗佈於保護膜上,硬化速度與前述組合物不同之似 黏土可硬化矽酮組合物之有機溶劑溶液同樣塗佈於另一薄 膜上,接著將似黏土可硬化矽酮組合物積層在一起,且接 著僅依似黏土可硬化矽酮組合物硬化之方法;其中將可硬 化碎酮組合物之有機溶劑溶液塗佈於保護膜上且使組合物 硬化,再將似黏土之可硬化矽酮組合物之有機溶劑溶液塗 佈於硬化產舞上之方法;及其$將液態可硬化矽酮組合物 塗佈於保護膜上且使組合物硬化,接著將含似黏土可硬化 矽酮組合物之甲苯、庚烷或另依該有機溶劑之溶液塗佈於 另一保護膜上’且將薄膜積層在一起之方法;其中將成分 (C)或成分(E)塗佈於保護膜上,同樣的將似黏土可硬化矽酮 組合物 < 有機溶劑溶液塗佈於另一保護膜上,以似黏土可 硬化矽酮組合物將成分(c)或成分(E)積層在一起,且接著僅 使似黏土可硬化矽酮組合物之一表面硬化之方法;其中之 保護膜藉由壓延覆蓋以可硬化矽酮組合物,且使組合物硬 化,再將似黏土可硬化矽酮組合物之有機溶劑溶液塗佈於 硬化產物上之方法。 本么月之諕以秒酮為基質之黏著板可用作所有類型基質 《黏著板’因為其可使平滑基質與具有不規則I面之基質 滿意的接合,且可使接合層之厚度接近均勻。尤其,使用 本發明之以相為基f之黏著板作為晶片附接元件與至少 86646 -20- 1293191 一表面具有不規則度之半導體晶片之黏著劑較有利,因為 可使接合層之厚度接近均勻,且因此在後續架線接合製程 上不會產生不便。本發明之該以矽酮為基質之黏著板適用 作供其至少一表面具有不規則性之半導體晶片與晶片附接 元件接合用之黏著劑。該板較好具有低含量之鈾及鉦。哕 板較好亦具有低含量鈉、鉀及其他該鹼金屬離子或南素離 子。另外,該板較好具有低含量之低分子量矽氧燒。 接合半導體晶片及晶片附接元件之方法 圖3說明本發明接合半導體晶片與晶片附接元件之方 法。該方法与括之步•驟為·· (1) 藉由分割由與晶圓9穩固接合之硬化矽酮層1〇、一層 與硬化層10穩固接合之似黏土可硬化矽酮組合物^、與組 合物層11穩固接合之保護膜12及黏著附接於薄膜12上之板 13組成之積層體製造半導體晶片; (2) 自晶片剥離保護膜12及黏著板13 ; (3) 經由组合物層^,藉由壓著半導體晶片與晶片附接 元件,使半導體晶片與晶片附接元件接合·及 (4) 使組合物層1 1硬化。 形成包括與曰曰圓9穩固接合之硬化矽酮層〗〇及與硬化層 1 〇U接合之似黏土可硬化梦酮組合物層!夏積層體之方法 之貫例g ;使包括一層與晶圓穩固接合之似黏土可硬化秒 酮組口物(I)、一層與組合物⑴穩固接合,且硬化速率低於 組合物(I)層义似黏土可硬化矽酮組合物(H)之積層體中之 組合物⑴層硬化’使組合物(ίΙ)之層免於硬化之方法;及其 86646 -21 -
