Abstract
半導体装置において、熱負荷に対する半導体パッケージと実装基板との接続部の信頼性を向上して大容量化、高機能化および省スペース化を可能とすること。
【解決手段】
半導体装置1は、半導体パッケージ2と、半導体パッケージ2に半田バンプ4を介して電気的に接続するランド8を有する実装基板5とを備える。実装基板5には、ランド8が複数配置された列が複数形成されている。半導体パッケージ外縁を構成する主辺に各々最も近い側に位置する列を構成するランド8の少なくとも一つは、ランド8から実装基板面に沿って延びる配線9を有する。配線9は、ランド8の中心から半導体パッケージ2の中心とを結ぶ線分より、線分にランド8の中心で直交する線分に近い側に、ランド8との連絡部が位置するように形成されている。
