Abstract
Description
第1実施形態では、電子デバイスとして、半導体発光装置(LEDデバイス)を一例に挙げて説明する。
p側配線層21及びn側配線層22が、第2の面側の領域の大部分を占めて広がっている。
なお、酸化ビスマスの代わりに酸化プラセオジムを用いても構わない。この場合にも、同様のバリスタ特性が得られることが知られている。また、酸化ビスマスを用いた場合に比べて、酸化プラセオジムを用いた場合には、1次粒子の大きさが小さくなることが知られている。従って、より微細な構造、すなわち、p側配線部とn側配線部との間隙をより狭くしたい場合においては、酸化プラセオジムを用いることがより好ましい。なお、粒界54近傍に高濃度に偏析される成分としては、酸化ビスマスと酸化プラセオジムに限る必要はない。要は1次粒子の粒界を介してバリスター特性を発現する組成であれば同様の効果が期待できる。また、粉体52の原料粉末としては、必ずしも酸化物でなくても構わず、例えばビスマス、プラセオジムなどを原料粉末として用いて、焼結中に酸化させても構わない。
図5は、図1(b)において2点鎖線で囲む部分の模式拡大断面図である。
第2実施形態においても、電子デバイスとして、半導体発光装置(LEDデバイス)を一例に挙げて説明する。
図28に示すp側金属ピラー23とn側金属ピラー24を形成した後に、レジストマスク93と92を除去し、不図示のシード膜60をp側配線層21とn側配線層22の直下部分を除いて除去する。その後、パシベーション膜(絶縁膜)18とp側配線層21とn側配線層22とp側金属ピラー23とn側金属ピラー24の表面に複合樹脂56を形成し、その上に樹脂66を形成する。その後、p側金属ピラー23とn側金属ピラー24が露出するまで樹脂66を研削した後、無電解メッキを行うことにより、図43の形態を得ることが出来る。樹脂66は、バリスター特性のない一般的な絶縁性の樹脂である。
図34(a)は、第3実施形態の半導体デバイス4の模式断面図である。
以上説明したバリスタ特性を持った複合樹脂は、図37(a)及び(b)に示すサイドビュータイプの半導体発光装置6にも適用することができる。
図37(b)は、第4実施形態の半導体発光装置6を実装基板310上に実装した構成を有する発光モジュールの模式断面図である。
以上説明したバリスタ特性を持った複合樹脂は、図44(a)、(b)に示す表面実装型の半導体発光装置にも適用することができる。
