Abstract
【解決手段】下面に熱硬化性の接着層13cが設けられた半導体部品13を、表面に樹脂層を有する基板5に接合する部品接合において、予め基板5の樹脂表面5aをプラズマ処理によって表面改質を行って濡れ性を向上させた後、加熱手段を有する部品保持ノズル12によって半導体部品13を保持し、表面改質された樹脂層に接着層13cを当接させ、接着層13cを加熱手段によって加熱して熱硬化させる。これにより接着層13cと樹脂表面5aの密着性を向上させて、部品保持ノズル12を接着層13cの完全硬化を待たずに半導体部品13から離隔させることができ、部品接合に要する時間を短縮して熱圧着工程の生産性向上を実現することができる。
【選択図】図2
Description
図1、図2、図3、図4,図5,図6は本発明の実施の形態1の部品接合方法の工程説明図である。ここに示す部品接合においては、表面にポリイミドやガラスエポキシなど樹脂層を有する基板に、熱硬化性の接着層が予め形成された半導体部品を熱圧着により接合して実装する。
いる。なお第2の半導体部品23を第1の半導体部品13上に積層した状態において第1の半導体部品13を対象としたワイヤボンディングの妨げとならないように、第2の半導体部品23の外形寸法は第1の半導体部品13よりも一回り小さく設定されている。
図7,図8,図9,図10は本発明の実施の形態2の部品積層方法の工程説明図である。この部品積層方法においては、一方の面に樹脂層を有し他方の面に熱硬化性の接着層を有する複数の部品を、基板5上において積層するものである。本実施の形態2では、2つの半導体部品を、スペーサ24を介して積層する例を示している。
から、半硬化状態の接着層26cは樹脂表面24cで速やかに流動して樹脂板24aと良好に密着する。
