Abstract
【解決手段】基板10上に、半導体層20、光反射層30および保護層31をこの順に積層して構成されたものである。半導体層20は、バッファ層21、GaN層22、n型コンタクト層23、n型クラッド層24、活性層25、p型クラッド層26およびp型コンタクト層27をこの順に積層して構成される。光反射層30は、例えば100℃以上400℃未満の範囲内の温度で基板10を加熱しつつ、Ag合金をp型コンタクト層27の表面に堆積させることにより形成されたものである。これら半導体層20、光反射層30および保護層31は、当該半導体層20、光反射層30および保護層31が形成されたのち、所定の時間範囲内の時間の間、雰囲気の温度を基板加熱時の温度範囲よりも高い温度範囲内の温度にして熱処理されたものである。
