Description
Ga2O3 + 4Ga → 3Ga2O。
このガリウム酸化物Ga2Oは、その融点に応じてさらす工程における基板温度の作用により、窒化ガリウム系半導体から真空チャンバの中空内に放出される。これ故に、半極性主面が電極膜と接合を形成することに先立って、酸素との結合性に富む半極性主面へのガリウム照射により半極性主面付近における酸素濃度を低減できる。したがって、良好なオーミック接触を有するIII族窒化物半導体発光素子を製造できる。
図6は、電極形成のための下地の窒化ガリウム系半導体領域における酸素濃度を二次イオン質量分析(SIMS)法で測定した結果を示す図面である。二次イオン質量分析の評価のために、以下のデバイス構造が準備された。横軸の左側から右側(深さ0.3μmから0.7μmの方向)の方法に以下の層が{20−21}GaN基板上に順に配列される。
ud-GaN:630nm。
p-GaN:50nm。
p-GaN:400nm。
n-GaN:1000nm。
図6に示された破線JC線までのエピタキシャル基板を準備する。エピタキシャル基板は、{20−21}GaN基板、n型GaN層(1000nm)、p型GaN層(400nm)、p型GaN層(50nm)を含む。n型GaN層(1000nm)、p型GaN層(400nm)、及びp型GaN層(50nm)は{20−21}GaN基板上に成長される。p型GaN層(50nm)の表面は、酸素を含む大気にさらされる。上記の構造を有するエピ基板A1、A2を準備した。分子エピタキシ(MBE)装置にエピ基板A1を配置した後に、Gaフラックスを照射することなく、p型GaN層(50nm)上にアンドープGaN(630nm)層をMBE法で成長してエピ基板B1を形成した。また、分子エピタキシ(MBE)装置にエピ基板A2を配置した後に、Gaフラックスを照射した後に続けてp型GaN層(50nm)上にアンドープGaN(630nm)層をMBE法で成長してエピ基板B2を形成した。
基板温度:摂氏750度。
Gaフラックス量:1.4×10−6Torr(1Torrは133.322パスカルで換算される)。
照射時間:30分。
発明者らは、Ga照射における真空度と基板温度との関係をシミュレーションにより見積もった。シミュレーションはOutotec Research Oy社製HSC Chemistryという化学反応/平衡の計算ソフトウェアを利用して導出した。見積もりを以下に示す。
雰囲気圧力、加熱温度(摂氏)。
7.50E-02、摂氏1070度以上。
7.50E-03、摂氏860度以上。
7.50E-04、摂氏710度以上。
7.50E-05、摂氏610度以上。
7.50E-06、摂氏540度以上。
7.50E-07、摂氏490度以上。
7.50E-08、摂氏450度以上。
7.50E-09、摂氏400度以上。
7.50E-10、摂氏370度以上。
7.50E-11、摂氏340度以上。
7.50E-12、摂氏310度以上。
7.50E-13、摂氏290度以上。
表示「7.50E-13」は“7.50×10−13”を示す。この見積もりによれば、Ga照射中における真空度の値を小さくする(高真空)につれて、基板温度を小さくできる。
