Abstract
【解決手段】第1導電型窒化物半導体層と、活性層と、第2導電型窒化物半導体層と、がこの順序で積層されている窒化物半導体発光素子を製造する方法であって、第1導電型窒化物半導体層の表面に凹凸を形成する工程と、第2導電型窒化物半導体層の表面に凹凸を形成する工程と、第1導電型窒化物半導体層側の第1電極と第2導電型窒化物半導体層側の第2電極とを活性層を挟んで対向する位置にそれぞれ形成する工程と、を含む、窒化物半導体発光素子の製造方法と窒化物半導体発光素子である。
【選択図】図1
Description
まず、基板としてサファイア基板を用意し、このサファイア基板の表面(C+面)上に窒化シリコン層からなるマスク層を形成した。次に、フォトリソグラフィ技術とフッ酸エッチャントを用いてマスク層の一部を除去し、サファイア基板の<11−20>に略平行な幅3μm程度のストライプ状のマスク層を残すとともに、幅2μmのストライプ状にサファイア基板の表面を露出させた。
内部量子効率(%)=100×(温度300KのときのPL光の強度)/(温度10KのときのPL光の強度)
また、実施例1の窒化物半導体発光素子の第2電極をステム上にAgペーストを用いてマウントし、第1電極にワイヤを接続することによって、一対のリードフレームの間に実施例1の窒化物半導体発光素子を電気的に接続した。そして、実施例1の窒化物半導体発光素子を砲弾型の透明樹脂によって封止することによって、図14に示す構成の発光装置を作製した。
p型GaNからなる第2導電型窒化物半導体層の表面に凹凸を形成しなかったこと以外は実施例1と同様にして窒化物半導体発光素子を作製した。これにより、n型GaNからなる第2導電型窒化物半導体層の表面のみに凹凸が形成された図15に示す構成の比較例1の窒化物半導体発光素子を得た。
