Description
本出願の対象は、ジョージ アール.ブランズ(Geore R.Brandes)、ロバート ピー.ヴァウド(Robert P.Vaudo)およびシェピン・シュ(Xueping Xu)の名で、「ミスカット基板上のレーザダイオード配向(LASER DIODE ORIENTATION ON MIS−CUT SUBSTRATES)」に対して2005年7月11日に出願された、米国仮特許出願第60/699,659号明細書の開示に関連するとともに包含するものである。このような仮出願の開示はあらゆる点でその全体を本明細書に引用して援用する。
本発明は一般に半導体デバイスに関し、特定の態様において窒化ガリウムなどのIII−V族窒化物材料のオフアクシス(off−axis)基板上のレーザダイオードの方向配置に関する。
窒化ガリウム(GaN)および関連するIII−IV族窒化物合金はバンドギャップの広い半導体材料であり、光電子機器(例えば青色およびUV発光ダイオードならびにレーザダイオードの作製)ならびに高周波、高温および高出力電子機器に用途がある。このような高性能デバイスでは高品質エピタキシャル膜を基板上に成長させなければならない。
本発明は一般に半導体デバイスに関し、特定の態様においてオフアクシスまたはオフカット基板上のレーザダイオードの方向配置に関する。
本明細書の以下の検討は主に本発明の適用に対する例示的III−V族窒化種としてのGaNを対象とするが、本発明が二元化合物および合金を始めとするIII−V族窒化物系化合物に広範に適用できることは認識されよう。
