Description
本発明は、半導体装置の部品の接合のための接合部材用の銀微粒子焼結体であって、銀微粒子焼結体のクリープの活性化エネルギーが、バルクの銀の格子拡散の活性化エネルギーの0.4〜0.75倍である、銀微粒子焼結体である。本発明により、半導体装置の応力を緩和することができ、かつ導電性を有する、半導体装置の部品の接合のための接合部材を得ることができる。
本発明の銀微粒子焼結体は、銀微粒子焼結体のクリープの活性化エネルギーが、バルクの銀の格子拡散の活性化エネルギーの0.4〜0.7倍であることが好ましい。銀微粒子焼結体のクリープの活性化エネルギーが、バルクの銀の格子拡散の活性化エネルギーの0.4〜0.7倍であることにより、確実に半導体装置の応力を緩和することができる。
本発明の銀微粒子焼結体は、1次粒子の平均粒子径が40〜350nmであり、結晶子径が20〜70nmであり、かつ結晶子径に対する平均粒子径の比が1〜5である銀微粒子を、温度130〜320℃に加熱することによって焼結した銀微粒子焼結体であることが好ましい。所定の銀微粒子を焼成、すなわち所定温度に加熱することによって焼結することにより、本発明の優れた特徴を有する銀微粒子焼結体を、確実に得ることができる。
本発明の銀微粒子焼結体は、銀微粒子焼結体の間隙が樹脂によって充填されていることができる。本発明の銀微粒子焼結体は、銀微粒子焼結体の間隙に樹脂を含む場合にも、十分に高い導電性を示し、かつ特殊なクリープ挙動示すことができる。
本発明は、半導体チップと支持体とが、接合部材によって接合されている半導体装置であって、接合部材が、上述の銀微粒子焼結体である半導体装置である。本発明の銀微粒子焼結体を、半導体チップと支持体とを接合するための接合部材として用いるならば、放熱特性に非常に優れるため、半導体素子から発生する熱を効率良く拡散することができる。
本発明は、第一の半導体チップと、配線基板又は第二の半導体チップとが、バンプを介して接合されている半導体装置であって、バンプの一部又は全部が、上述の銀微粒子焼結体である半導体装置である。本発明の銀微粒子焼結体をバンプとして用いるならば、MOSFETやLEDなどのチップと、基板との熱膨張係数の差によって生じるひずみを緩和することによって、半導体装置に生じるクラック等を抑制することができる。
本発明は、半導体装置の部品の接合のための接合部材用の銀微粒子焼結体の製造方法であって、1次粒子の平均粒子径が40〜350nmであり、結晶子径が20〜70nmであり、かつ結晶子径に対する平均粒子径の比が1〜5である銀微粒子を、温度130〜320℃でに加熱することによって焼結する工程を含む、銀微粒子焼結体の製造方法である。本発明の製造方法により、半導体装置の応力を緩和することができ、かつ導電性を有する、半導体装置の部品の接合のための接合部材を得ることができる。
本発明は、半導体チップと支持体とが接合部材によって接合されている半導体装置の製造方法であって、1次粒子の平均粒子径が40〜350nmであり、結晶子径が20〜70nmであり、かつ結晶子径に対する平均粒子径の比が1〜5である銀微粒子を含む導電ペーストを支持体上に供給する工程と、支持体上に半導体チップを位置合わせして載置する工程と、支持体、導電ペースト及び半導体チップを、温度130〜320℃に加熱することによって焼結する工程とを含む、半導体装置の製造方法である。本発明の半導体装置の製造方法を用いるならば、支持体上と半導体チップとの間の接合の応力を緩和することができるので、半導体装置に生じるクラック等を抑制することができる。
