Description
〔1〕(A)液状エポキシ樹脂、(B)アミン化合物のエポキシアダクト硬化剤またはマイクロカプセル化イミダゾール化合物硬化剤、(C)無機フィラー、(D)ホウ酸トリイソプロピルおよび(E)フェノール樹脂を含み、
液状エポキシ樹脂組成物:100質量部に対して、(C)成分が20〜65質量部であり、(D)成分が0.02〜0.30質量部であり、(E)成分が0.3〜15.0であることを特徴とする、液状エポキシ樹脂組成物。
〔2〕上記〔1〕記載の液状エポキシ樹脂組成物を含む、アンダーフィル材。
〔3〕上記〔1〕記載の液状エポキシ樹脂組成物を含む、接着剤。
〔4〕上記〔2〕記載のアンダーフィル材の硬化物、または請求項3記載の接着剤の硬化物を含む、半導体装置。
液状エポキシ樹脂組成物:100質量部に対して、(C)成分が20〜65質量部であり、(D)成分が0.02〜0.15質量部であり、(E)成分が0.3〜15.0であることを特徴とする。
表1〜表4に示す配合で、樹脂組成物を作製した。作製した樹脂組成物は、すべて液状であった。
作製した直後の樹脂組成物の粘度(以下、初期粘度という。単位:mPa・s)を、東機産業社製E型粘度計(型番:TVE−22H)を用い、毎分10回転の条件で測定した。初期粘度は、1000〜80000mPa・sであると好ましく、1000〜8000mPa・sであると、より好ましい。また、樹脂組成物を25℃で48時間保持した後の粘度も同様に測定し、粘度増加率(単位:%)を算出した。ここで、粘度増加率は、下記式:
粘度増加率=〔(48時間後の粘度)−(初期粘度)〕/(初期粘度)×100
で算出した。表1〜表4に、測定結果を示す。
樹脂組成物の揺変指数を、東機産業社製E型粘度計(型番:TVE−22H)を用いて測定した。揺変指数は、毎分1回転の条件で求められた測定値を、毎分10回転の条件で求められた測定値で除した比率、すなわち、(毎分1回転での粘度)/(毎分10回転での粘度)がから求めた。揺変指数の適正範囲は、0.8〜1.0である。表1〜表4に、測定結果を示す。
図1に、樹脂組成物の注入性の評価方法を説明する模式図を示す。まず、図1(A)に示すように、基板20上に50μmのギャップ40を設けて、半導体素子の代わりにガラス板30を固定した試験片を作製した。但し、基板20としては、FR4基板を使用した。次に、この試験片を50℃に設定したホットプレート上に置き、図1(B)に示すように、ガラス板30の一端側に、作製した樹脂組成物10を塗布し、図1(C)に示すように、ギャップ40が樹脂組成物11で満たされるまでの時間を測定した。注入時間の適性範囲は、1000秒以内である。表1〜表4に、注入性の評価結果を示す。
樹脂組成物の注入性の評価した試験片をオーブンへ入れ、120℃で3分間加熱し、エポキシ樹脂組成物を硬化させた。加熱後の硬化物外観を目視観察した。硬化物にしわ・柚子肌等の外観不良や色むらが認められなかった場合を○とし、硬化物にしわ・柚子肌等の外観不良や色むらが認められた場合を×とした。表1〜表4に、硬化物外観の評価結果を示す。
ガラスエポキシ基板に評価用試料を印刷し、該試料上に2mm×2mmのシリコンチップを載置した。これを、80±2℃の熱風乾燥機で90分間加熱硬化、または100±2℃の熱風乾燥機で90分間加熱硬化させた。これを試験片とし、dage社製万能型ボンドテスター(型番:DAGE4000)を用いてシリコンチップに荷重をかけ、チップが剥離した時の強度(剥離強度)を測定した。n=10とし、その平均値を強度とした。なお、100N未満の場合は、未硬化とした。表1〜表4に、強度の評価結果を示す。
20 基板
30 ガラス板
40 ギャップ
