Description
本発明は、薄い波長変換素子を有する波長変換発光デバイスを形成する方法に関する。
emitting lasers)を含む半導体発光デバイスは、現在入手できる最大効率光源に属する。可視スペクトルにわたり動作可能な高輝度発光デバイスの製造において現在興味ある材料系は、III−V族半導体、特に、III−窒素材料とも呼ばれる、ガリウム、アルミニウム、イリジウム及び窒素の二元、三元、四元合金を含む。代表的には、サファイア、シリコンカーバイド、III−窒素その他の好適な基板上に、金属有機化学蒸着(MOCVD)、分子ビームエピタキシ(MBE)その他のエピタキシャル技法によって、異なる混合物及びドーパント濃度の半導体層の積み重ねをエピタキシャル成長させることにより、III−窒素発光デバイスが製造される。該積み重ねはしばしば、基板上で形成した、例えばシリコンでドーピングした1層以上のn型層と、n型単一層又複数層の上で形成した、活性領域内の1層以上の発光層と、活性領域上で形成した、例えばMgでドーピングした1層以上のp型層とを含む。n型及びp型領域上に、電気的接続が形成される。
好適なIII−窒素LEDの一例を図5に示す。
