Abstract
【解決手段】主面3aの外周部に並んで配置された複数のボンディングリード3hを有するパッケージ基板3と、パッケージ基板3の主面3aのボンディングリード列の内側に搭載された半導体チップ1と、半導体チップ1のパッド1cと基板のボンディングリード3hとを接続するワイヤ4と、半導体チップ1及び複数のワイヤ4を樹脂封止する封止体と、パッケージ基板3の裏面に設けられた複数の半田バンプとを有している。さらに、ワイヤ4のループの頂点4bがワイヤ接続部4aより外側に配置されていることにより、ボンディングリード3hと半導体チップ1のパッド1cとの接続においてワイヤ長を長くすることができ、その結果、ワイヤ4のループ形状の安定化を図ってワイヤ接続不良の抑制化を図る。
