Description
集積回路が形成された半導体チップと、
前記半導体チップに形成され、前記集積回路に電気的に接続された電極と、
前記半導体チップ上に配置された樹脂突起と、
前記電極上から前記樹脂突起上に至るように配置された配線と、
配線パターンが形成され、前記配線の前記樹脂突起上の部分が前記配線パターンと対向して電気的に接続するように前記半導体チップが搭載された配線基板と、
前記半導体チップと前記配線基板を接着する接着剤と、
を有し、
前記樹脂突起は、前記半導体チップと前記配線基板の間隔が狭くなる方向に圧縮されており、
前記樹脂突起は、少なくとも25℃以上かつ前記接着剤のガラス転移点以下の温度領域で熱膨張率が負の材料からなる。本発明によれば、樹脂突起は、熱膨張率が負である
ため、加熱されると収縮する。したがって、接着剤が軟化することで樹脂突起の圧縮力が
解除され、樹脂突起が復元したとして、収縮もするので接着剤に発生する半導体チップと
基板間に発生する引っ張り応力(半導体チップと基板の間隔を広げようとする力)が減少
する。つまり軟化した接着剤の伸びを抑制でき、樹脂突起の圧縮状態が維持される。これ
により、熱膨張に起因する電気的な接続不良の防止を図ることができる。
(2)この電子デバイスにおいて、
前記樹脂突起は、液晶ポリマー、ポリパラフィニレンベンズビスオキサゾール及びポリ
イミドベンゾオキサゾールからなるグループのいずれか1つから形成されてもよい。
(3)この電子デバイスにおいて、
前記樹脂突起は、フェノール類ノボラック硬化剤と多官能エポキシ樹脂にゴム弾性微粒
子を分散させた混合樹脂から形成されてもよい。
