Description
リードフレームを用いた半導体装置では、半導体装置全体の厚さと面積が大きくなる。また、前記特許文献1に示された方法によれば、半導体素子の搭載されるPWBの表裏2面にパターンを形成する必要があるので、銅箔を表裏に貼付した構造の両面基板を用いなければならず、スルーホールも所定数だけ形成する必要があった。さらに、半導体素子の搭載部分を薄型化するためには、PWBに座ぐり加工を施す必要もあった。即ち、加工面及びコスト面で大きな課題があり、技術的に満足できるものが得られなかった。
完成した半導体装置において、球状の導電体61の仮固定された側が、他の基板70に対して対向して置かれ、ソルダーペーストを用いたリフロー実装等の手法で、この半導体装置が基板70に実装される。
