Description
また,封止材9の線膨張係数があまり大きくない場合には,半導体装置の端部に配置されている外部端子10bに発生するひずみも大きくなることがあり,半導体素子1端部に近接する外部端子10aと同様に破断が発生する可能性がある。
本発明は,外部端子の破断を防止・抑制し,信頼性の高い半導体装置,特にボールグリッドアレイ(BGA)型の半導体装置を提供することを目的とする。
、前記第一の絶縁部材の前記外部端子が配設された面とは反対側に配設された半導体素子と、前記半導体素子と前記外部端子を電気的に接続する導電性部材と、前記第一の絶縁部材の前記外部端子が配設された面とは反対側に配設された封止部材とを備えた半導体装置において、前記半導体素子と前記第一の絶縁部材との間には第二の絶縁部材が介在しており、前記第二の絶縁部材の外縁部が前記半導体素子の外縁部よりも突出していること。
、前記第一の絶縁部材の前記外部端子が配設された面とは反対側に配設された半導体素子と、前記半導体素子と前記外部端子を電気的に接続する導電性部材と、前記第一の絶縁部材の前記外部端子が配設された面とは反対側に配設された封止部材とを備えた半導体装置において、前記半導体素子と前記第一の絶縁部材との間には第二の絶縁部材が介在しており、前記第二の絶縁部材の外縁部が、前記半導体素子の外縁部よりも外側に位置する外部端子であって最も前記半導体側に存在する外部端子の外縁部に対応する位置まで延在していること。
一方フィルム状材料によって接着部材を形成する場合は,フィルムの厚さがほぼ均一となっているため,接着後の接着部材厚さの制御が容易であり,半導体装置の製造も従来と同様のプロセス行うことができる。フィルム状の接着部材では,半導体素子接着後の接着部材の厚さを絶縁性テープの厚さと同等の約50〜80μmにすることができる。これによって,接着部材の変形能力が向上し,外部端子のひずみ低減効果が大きくなる。
・半導体装置外形:13mm×13mm
・半導体素子外形:8.8mm×8.8mm
・外部端子数:176個
・外部端子間隔:0.8mm
図1は,本発明の第1参考例に係る半導体装置の断面図であり,図2は封止材を取り除いた状態での平面図である。
はんだ(例えばPb−Sn系共晶はんだ)などの材料を用いる。絶縁膜6はソルダーレジストとも呼ばれており,エポキシ樹脂,ポリイミド樹脂,ポリブタジエン樹脂などの材料が用いられる。
Claims (1)
- 複数のボンディングパッド及びランド、前記ボンディングパッドとランドを電気的に接続する導電性配線とを有する絶縁性テープと、半導体素子と、前記半導体素子と前記ボンディングパッドとを電気的に接続する導電性部材と、前記絶縁性テープの前記半導体素子搭載面で前記導電性配線を覆う絶縁膜と、前記半導体素子を前記絶縁膜の半導体素子搭載面に接着する接着部材と、前記半導体素子と導電性部材の周囲を封止する封止材と、前記ランドに接合される外部端子と、を備え、
前記複数のランドのうち、前記ボンディングパッドより中央側に配置されるランドは前記絶縁膜を介して前記接着部材により覆われ、前記ボンディングパッドより外側に配置されるランドは前記絶縁膜を介して低弾性部材により覆われ、前記接着部材及び前記低弾性部材を前記絶縁性テープより低弾性率の材料で形成したことを特徴とする半導体装置。
