Description
また、ソルダレジストは、一般にエポキシ樹脂などの有機物なので、半田耐熱がそれほど高くなく、例えば、水素ガス雰囲気中のフラックスレス半田付けの際に、ソルダレジストからのアウトガスの発生により半田付け性が阻害され、装置の汚染などの問題があり、使用が制限されていた。
図1は、本実施の形態の半導体装置の主要部の斜視図である。
本実施の形態の半導体装置10は、回路基板11の一方の面に半導体チップ12を、他方の面にこの半導体チップ12で発生した熱を放熱させる金属ベース13を接合したものであり、複数の回路基板11を金属ベース13上へ接合する際に用いる半田14の流動を制限するダム材15を金属ベース13上に配置した構成となっている。
金属ベース13は、搭載されている半導体チップ12で発生した熱を放熱させる機能を有するヒートシンクであり、例えば、Ni(ニッケル)がめっきされたCu(銅)が用いられる。
図2、3は、ダム部のパターンを示す図である。
ダム材15に用いる材料は、半田耐熱性の高い無機材料を主成分とするものを用いる。具体的には、カーボンやセラミックスの微粒子を主成分とし、このような微粒子を揮発性のあるバインダーと混成したものを用いる。セラミックスを主成分としたダム材として、セラミックス製の部材の接合に用いるセラミックス接着剤を適用してもよい。セラミックス接着剤は、珪酸と硼酸を主成分とし1000℃以上に耐える。ただし、セラミックス接着剤の中で、有機バインダーが乾燥後に残らないものを用いる。これにより、水素還元雰囲気での半田付けに使用できる。セラミックス系の場合は、絶縁性がよいものを選び厚く塗布することで、ダム効果と電気的絶縁が更に高まる。これらの材料により、例えば、ディスペンサによる微小塗布技術を用い、金属ベース13上に所定のパターンのダム材15を描画して形成する。スクリーン印刷の手法を用いてもよい。これにより、数のまとまった量産品を、効率よくインライン自動化で製造することができ、半導体装置10の高品質・高信頼性・低価格・製作期間短縮が図れる。
図4は、金属ベースへカーボン治具を取り付けた状態を示す図である。
