Abstract
【解決手段】 半導体装置であって、配線部材と、配線部材の上部に配置されている半導体チップと、半導体基板の上部に配置されている金属ブロックを有する。半導体チップが、半導体基板と、下部電極と、上部大電極と、上部小電極を有する。半導体チップが、その重心に対して上部小電極側に位置する第1部分と、反対側に位置する第2部分を有している。金属ブロックの重心が第2部分の上部に配置されている。下部電極が、下部はんだ層によって配線部材に接続されている。下部はんだ層が、はんだ母材と金属粒子を有する。第2部分の下部に位置する下部はんだ層中に占める金属粒子の体積比率が、第1部分の下部に位置する下部はんだ層中に占める金属粒子の体積比率よりも高い。
