Description
このようにバンプまたは半田ボールの接合力向上にフラックス処理が採用されているが、そのために2つの工程(フラックスの塗布および洗浄ないし除去工程)が必要となる。
また、この硬化剤を用いた場合、アルミニウムやその他種々の金属に対し接着性能が良好で、しかも強靭な硬化物性を有することから、接着剤(特に構造用接着剤)、塗料、コーティング材、封止材等への用途拡大が認められた。
なお、このアンダーフィル材用途にあって、必要に応じて接着性や浸透性を改善するために、オルガノシリコーン化合物(たとえばシランカツプリング剤、末端シラノール基含有オルガノポリシリコーン、ポリエーテル変成シリコーンなど)を通常、組成物全量中0.01〜10重量%の量で配合されてもよい。
また、かかるアンダーフィル材用途以外にも、接着性能や強靭な硬化物性を有することから、接着剤、塗料、コーティング材、封止材等にも適用しうる。かかる用途にあって、さらに必要に応じて、通常の添加剤、たとえば反応性希釈剤(ブチルグリシジルエーテル、N,N’−ジグリシジル−o−トルイジン、フェニルグリシジルエーテル、スチレンオキサイド、エチレングリコールジグリシジルエーテル、プロピレングリコールジグリシジルエーテル、1,6−ヘキサンジオールジグリシジルエーテルなど)、非反応性希釈剤(ジオクチルフタレート、ジブチルフタレート、ジオクチルアジペート、石油系溶剤など)等を適量配合されてよい。
すなわち、フリップチップまたは半導体パッケージを配線基板(たとえばガラスエポキシ樹脂、ABS樹脂、フェノール樹脂等からなる基板)に対しバンプ(高さ10〜100μm)または半田ボール(高さ300〜800μm)を介して接続(ボールピッチ20〜500μm)する工程と、該接合部の隙間にアンダーフィル材(本発明の一液加熱硬化型エポキシ樹脂組成物)を、液体精密定量吐出装置で塗布し、130〜270℃×2秒〜6時間の加熱処理で硬化封止させる工程を順次もしくは逆順または同時に行なって、半導体実装を行なう。このようにバンプまたは半田ボールの接合力向上に採用されていたフラックス処理を省略しても十分満足できる接合力を確保することができる。
参考例1
エポキシ樹脂の硬化剤種を変えた場合の、フラックス性能を調べる。
銅箔上に下記検討資材を塗り、これにフラックスを含まない半田片を置いた後、銅箔を250℃に加熱して半田を溶融せしめ、そのときの半田の拡がり(フラックス性能)を観察する。結果を下記表1に示す。
○:フラックス性能あり
×:フラックス性能なし
△:○〜×の中間
なお、検討資材は、ビスフェノールA型エポキシ樹脂(油化シェルエポキシ(株)製「エピコート828」、エポキシ当量190)に、表1の各硬化剤を約当量程度になるように配合したものを使用する。
ビスフェノールA型エポキシ樹脂(「エピコート828」)に対して、硬化剤として無水メチルハイミック酸とコハク酸を併用した場合のフラックス性能を検討し、結果を下記表2に示す。なお、各硬化剤の使用量(重量部数)にあって、たとえば「90」は、エポキシ樹脂100部(重量部、以下同様)の内、その90部を硬化させることを意味する(以下同様)。
下記表3に示す部数の成分を配合して、一液加熱硬化型エポキシ樹脂組成物を調製し、フラックス性能および下記のボイドレス性を調べ、結果を表3に併記する。
ボイドレス性
アルミニウム板に上記エポキシ樹脂組成物を塗布し、スペーサー(厚み50μm)を置き、スライドガラスを載せ、ホットプレート(250℃)上に置き、揮発性による発泡の有無を確認する。
○:良好、×:不良、△:やや良好
