Abstract
多種の半導体チップに対応する接続子とリード片で挟み込む構造をとる樹脂封止型半導体装置の接続子の種類を削減する事。多品種の半導体チップに対応する接続子とリード片で挟み込む構造をとる樹脂封止型半導体装置の接続子の組立時位置決めを容易にし、製造コストを削減する事。樹脂封止後の製品を切断分割する際の品質低下を防ぐ事を課題とする。
【解決手段】
リード片1aに半導体チップ2、リード片1bに半導体チップ2と同じ厚さを持つ第2金属片4を載せ、それらをまたぐ形で第1金属片を載せて樹脂封止している。リード片1a,1bは樹脂部7の底面に部分的に露出している。半導体チップ2は上面下面の両面に電極を持っている。またリード片1aは半導体チップ2の下面電極に接続されており、第1金属片の一端は半導体チップ2の上面電極に接続されている。
