Description
〔1〕(A)平均粒子径が100nm以下の金属ナノ粒子と、(B)沸点が50〜100℃の溶剤と、(C)沸点が150〜200℃の溶剤を含有し、(B)成分と(C)成分の合計100質量部に対して、(B)成分を10〜30質量部含有することを特徴とする、接合用ペースト。
〔2〕(A)成分の粒径の変動係数が50〜65%である、上記〔1〕記載の接合用ペースト。
〔3〕被接合体が、半導体素子と基板である、上記〔1〕または〔2〕記載の接合用ペースト。
〔4〕半導体素子が、LED素子である、上記〔3〕記載の接合用ペースト。
〔5〕基板上に、上記〔3〕または〔4〕記載の接合用ペーストを塗布し、乾燥した後、接合用ペースト上に半導体素子を載置し、加熱することを特徴とする、半導体素子と基板の接合方法。
本発明の接合用ペーストは、(A)平均粒子径が100nm以下の金属ナノ粒子と、(B)沸点が50〜100℃の溶剤と、(C)沸点が150〜200℃の溶剤を含有し、(B)成分と(C)成分の合計100質量部に対して、(B)成分を10〜30質量部含有することを特徴とする。
(A)成分は、平均粒子径が100nm以下の金属ナノ粒子である。金属としては、Ag、Au、Pt、Pd、Ru、Ni、Cu、Sn、In、Zn、Fe、Cr、Mn等が挙げられ、低温での焼結性、製造の容易性などの観点から、Ag、Au等が好ましく、さらにコスト面からAgがより好ましい。
(B)成分は、接合用ペーストに塗布時の流動性を付与する。(B)成分は、沸点が50〜100℃であるので、塗布時には接合用ペースト中に残存して流動性を付与し、乾燥後には揮発して接合用ペーストの流動性を抑え、接合用ペーストのにじみを防止することができる。また、乾燥後に揮発することにより、半導体素子と基板間のボイド発生を抑制し、ボンディング性を向上させる。また、(B)成分は、20℃での蒸気圧が10hPa以上であると、乾燥後の揮発を容易にするため、好ましい。
(C)成分は、接合用ペーストに塗布時の流動性と、乾燥後の粘着性を付与する。(C)成分は、沸点が150〜200℃であるので、接合用ペーストを乾燥した後にも接合用ペースト中に残存し、かつ接合ペースト中の金属ナノ粒子が焼結する際には揮発し、残渣等にならず、半導体素子と基板間のボイド発生を抑制する。また、(C)成分は、20℃での蒸気圧が10hPa未満であると、乾燥後の揮発が抑制されるため、好ましい。
本発明の半導体素子と基板の接合方法は、基板上に、上記接合用ペーストを塗布し、乾燥した後、接合用ペースト上に半導体素子を載置し、加熱することを特徴とする。
