Abstract
Description
一面に露出した第1電極(14)と、一面の反対面に露出した第2電極(12、22)とを有する半導体素子(1、2)と、
半導体素子が実装され第1電極が電気的に接続された実装部(32、42)と、実装部と分割された非実装部(31、41)とを含むリードフレーム(30、40)と、
第2電極と非実装部とを電気的に接続している導電性の架橋部材(51、52)と、
電気的な絶縁性を有し熱伝導率が2.2W以上であり、実装部の実装面(S12)の反対面(S11)が露出した状態で、半導体素子及びリードフレーム及び架橋部材を覆う封止樹脂(7)と、を備えていることを特徴とする。
半導体装置100は、図4に示すように、プリント板200に実装され、且つ、ゲル400を介してモータ300に取り付けられてもよい。プリント板200は、電気絶縁性の樹脂などからなる基板に、導電性部材からなる配線やパッドが形成されている。半導体装置100は、第1ソース端子31、第1ドレイン端子32、第1信号端子33がはんだなどの導電性部材を介して、プリント板200のパッドに電気的に接続されている。
図5に示すように、半導体装置110は、半導体素子1、2の配置が半導体装置100と異なる。半導体装置110は、第1半導体素子1と第2半導体素子2を交互配置してもよい。つまり、半導体装置110は、第1信号端子33に隣り合って第2ソース端子41が配置され、第1ソース端子31に隣り合って第2信号端子43が配置されている。半導体装置110は、半導体装置100と同様の効果を奏することができる。
