Description
まず、LEC法により作製したGaP単結晶棒を切断して、複数のn型GaP単結晶基板10を得た。それらn型GaP単結晶基板10上に、前述した成長容器20内でn型GaPバッファ層11を液相エピタキシャル成長させて、複数のGaPエピタキシャルウェーハ3を得た。次に、スライドボート法を採用した液相成長装置60(図3参照)を使用して、各GaPエピタキシャルウェーハ3上にGaP層12,13,14を形成することにより、多層構造のGaP発光素子1を作製した。
3 GaPエピタキシャルウェーハ
10 n型GaP単結晶基板
11 n型GaPバッファ層(結晶性改善層)
12 n型GaP層
13 Nドープn型GaP層
14 p型GaP層
Claims (1)
- n型GaP単結晶基板の{111}B面に、n型GaP層が形成されたGaPエピタキシャルウェーハを複数製造し、各GaPエピタキシャルウェーハの{01−1}へき開面を選択エッチングし、該選択エッチングされた前記へき開面上にて、前記n型GaP層内の、該n型GaP層の成長界面に平行な面と交差して延びる櫛歯状の結晶欠陥の本数を計数し、当該結晶欠陥の本数が100μmあたり30本以下のGaPエピタキシャルウェーハを選別し、その選別されたGaPエピタキシャルウェーハを用いてGaP発光素子を製造することを特徴とするGaP発光素子の製造方法。
