Description
配線部は、基板垂直方向の正射影が、導電性バンプより小さいか、実質的に等しいサイズにすることが好ましい。この場合、導電性バンプは、配線部の側面全体を覆い、配線部全体を保護することが可能だからである。
このような低弾性のコアを有する導電性バンプを使用することにより、装置を実装基板に実装し、製品として使用する環境において発生する応力を導電性バンプが軽減するため、導電性バンプを電極パッドの実質的直上の位置に配置しても、電極パッドに加わる応力を軽減できるため、電極パッドでのクラック発生を抑制できる。導電性バンプの最外層にはんだ層を備えることにより、配線部上の所定の位置に低弾性率のコアを有し最外層がはんだよりなる球状体を搭載し、その後、リフローによりはんだ層を溶解させ配線上に導電性バンプを形成することができ、既存のはんだと同様の安価な方法で製造できる。導電層を溶融させるときにコアも高温になるので、コアの材料には、高い耐熱性を有するものを用いることが好ましい。
この場合、電極パッド5と導電性バンプ13との距離が短くなり、従って、両者を接続する配線距離が短くなるため、寄生容量等を減少させることができる。
