以下に、本発明にかかる実施の形態を図面に基づいて詳細に説明する。
図1は、本第1実施形態における実装方法によって得られる半導体パッケージ(半導体の一例であって、半導体素子単体である場合、および半導体素子を含むパッケージとして構成される場合を含む。)1の実装構造体10の概略部分断面図である。図1に示すように、実装構造体10は、複数の電極2を有するBGA半導体パッケージ1と、それぞれの電極2上に形成されたはんだバンプ3と、複数の基板電極(第2電極の一例)5を有する回路基板4と、はんだバンプ3と回路基板4の基板電極5との間に介在して、はんだバンプ3と基板電極5とを電気的に接続する接合部材9と、それぞれの接合部材9の周囲に配置され、接合部材9を補強する補強樹脂(補強樹脂部材)6とを備える。
本第2実施形態は、本発明の1つの形態における半導体パッケージ1の実装方法、すなわち半導体パッケージ1の実装構造体10の製造方法に関するものであり、図2、図3、および図4を用いて3つのパターンの実装方法(製造方法)1、2、3について説明する。なお、図1に示す実装構造体10と実質的に同じ構成部材には、同じ参照番号を付してその説明を省略する。
まず、実装方法1について説明する。図2に示すように、回路基板4の基板電極5上に、Snと、Bi、In、AgおよびCuの群から選ばれる2種もしくはそれ以上の元素との組合せからなる合金組成のはんだ材料と、未硬化状態の熱硬化性樹脂とが混ざった混合ペースト71(すなわち、はんだ材料と熱硬化性樹脂との混合ペースト)を印刷する。その後、BGA半導体パッケージ1の電極2上に形成されたそれぞれのはんだバンプ3と、回路基板4の基板電極5上に印刷された混合ペースト71との位置合わせを行い、はんだバンプ3と混合ペースト71とを接触させるように、回路基板4上にBGA半導体パッケージ1をマウントする。
次に、実装方法2について説明する。図3に示すように、回路基板4の基板電極5上にSnと、Bi、In、AgおよびCuの群から選ばれる2種もしくはそれ以上の元素との組合せからなる合金組成のはんだペースト7を印刷する。次に、未硬化状態の熱硬化性樹脂8を、Snと、Bi、In、Ag、ZnおよびCuの群から選ばれる2種もしくはそれ以上の元素との組合せからなる合金組成からなるBGA半導体パッケージ1のはんだバンプ3上に転写する。熱硬化性樹脂の転写は、樹脂をスキージで0.1~1mm程度の均一な薄さに広げ、そこにBGA半導体パッケージ1のはんだバンプ3を載せることで行う。
次に、実装方法3について説明する。図4に示すように、回路基板4の基板電極5のパッド上にのみ、はんだペースト7を印刷する。その後、未硬化状態の熱硬化性樹脂8をスクリーン印刷やディスペンサーなどで回路基板4上に供給する。供給場所ははんだペースト7の上でも、その周辺でもよく、また、回路基板4の全ての基板電極5上、あるいは、回路基板4における中央部や四隅など、一部の基板電極5の周囲でもよい。熱硬化性樹脂8の供給量は、実装完了後に熱硬化性樹脂8(すなわち補強樹脂6)が、それぞれの補強樹脂6が接合部材9とはんだバンプ3との接合部分および接合部材9を覆い、かつ補強樹脂6が半導体パッケージ1に接触することなく、さらに隣接する補強樹脂6同士が互いに離間するように、調整する。このような熱硬化性樹脂8の供給量の調整に加えて、図4に示すように、それぞれの基板電極5の間における回路基板4上に突起部材4aを設けても良い。このように突起部材4aを設けることにより、実装完了後に、回路基板4と補強樹脂6との接合強度を向上させながら、隣接する補強樹脂6同士を確実に離間させることができる。なお、隣接する熱硬化性樹脂7間にスペースSを設けることができれば、このように突起部材4aを設けるような場合に代えて、他の様々な手段を採用しても良い。
本発明の実施例として、上述の実装方法2を用いて実装したBGA型半導体パッケージ1の実装構造体10について、はんだペーストの種類とリフロー温度、補強樹脂の量を変化させ、耐衝撃性やリペア性への影響を調べ、図5の表にその結果を示した。図5の表としては、本発明の実装方法2を用いて実装した実装構造体10の実施例1~6と、比較対象となる比較例1~4について示している。
図5の表に示す測定結果において、実施例4(補強樹脂高さが50%)と比較例3(補強樹脂高さが100%)を対比すると、耐落下寿命では同程度の結果を得ながら、比較例3ではリペア性が著しく劣り、実施例4が良好な結果を得ている。また、実施例4(補強樹脂高さが50%)と比較例4(補強樹脂高さが0%)を対比すると、比較例4では、耐落下寿命が著しく劣り、実施例4が良好な結果を得ている。
