Abstract
【解決手段】半導体チップ1を搭載するための半導体チップ搭載領域2を有する面とは反対面に外部接続端子が設けられている配線基板8において、半導体チップ1を搭載するための半導体チップ搭載領域2に、自身に含まれる全ての配線の末端が半導体チップ搭載領域2内では開放されている形状のダミー配線6が配置されている。
【選択図】図1
Description
外部接続端子として無鉛半田を用い、接続する際の温度を共晶半田の場合よりも高く設定しても、水分が膨張することによる半導体装置における不具合は発生することはない。よって、信頼性のある高品質な半導体装置を提供することができる。
上記構成によると、半導体チップと配線基板との間で吸湿された水分が溜まることがないので、熱が加えられても、水分が膨張することによる半導体装置における不具合を防止することができる。このように、上記形状のダミー配線を配置することで、簡易な構成でコストをかけずに、水分が膨張することによる半導体装置における不具合を防止することができる。具体的には、半導体装置の外形が変形して不良になったり、実装基板に実装できなくなったり、また、内部の配線が断線したりする、といった不具合を防ぐことができる。よって、上記構成の配線基板を用いることで、信頼性のある高品質な半導体装置を製造することができる。
本発明の一実施形態について図1〜図4に基づいて説明すると以下の通りである。図1に示す本実施形態の配線基板8では、配線基板8の基材上に、信号配線パターン(信号配線)3,4,5が配置されており、また、半導体チップ搭載領域(搭載領域、半導体チップ搭載下部)2にダミー配線(ダミー配線パターン)6が設けられている。信号配線パターンには、外部接続端子用ランド(メタルランド)部として用いられる部分である信号配線パターン4と、ワイヤボンド接続部として用いられる部分である信号配線パターン5と、これらの間を結ぶ部分である信号配線パターン3とからなっている。
上記実施の形態で説明した、図1に示すダミー配線を有する配線基板を作成し、これについて検証を行った。配線基板の基材として、0.06mmのコア基板を用いて、サブトラクティブ工法による配線加工で信号配線パターンおよびダミー配線を、膜厚15μm程度で形成した。図1に示すダミー配線の配線幅は50μmであり、配線間スペースも50μmとした。
