Description
図1は第1の実施形態による半導体装置の断面図である。図1の半導体装置は、フォトカプラ1の例を示している。図1のフォトカプラ1は、LED(発光素子)2と、LED2に対向配置された受光素子3とを備えている。LED2は、ボンディングワイヤ4にて第1リードフレーム5に接続され、受光素子3は、別のボンディングワイヤ4にて第2リードフレーム6に接続されている。
第1絶縁層22は、その材料によっては、GaAs基板11との密着性があまりよくない場合がありうる。第1絶縁層22とGaAs基板11との密着性が悪いと、第1絶縁層22とGaAs基板11との間に隙間が生じ、この隙間から水分等が第1絶縁層22の内側に入り込み、発光強度や発光寿命を低下させたり、剥離が生じる要因になりうる。
