Description
本発明の他の目的は、低温バッファ層を形成しなくてもMOCVDを用いてサファイア基板に窒化物半導体層を成長させる窒化物半導体構造を提供することにある。
また、先行段階においてMOCVD反応機の内壁に蒸着されたGaNをソースに使用できる為、工程段階を縮減するのと同様な効果を得られ、工程短縮により原料及び費用を節減することができる。また、一つのMOCVD反応機内において全工程を行える利点がある。
本発明の第1実施例によると、従来の技術と異なり、1段階(S101)においてMOCVD反応機の内壁に窒化ガリウム(GaN)を蒸着させ、2段階(S102)においてサファイア(Al2O3)基板を上記MOCVD反応機内に装入する。
次いで、従来の技術と異なり、2段階(S202)として上記MOCVD反応機内に装入された上記サファイア基板を加熱し、トリメチルガリウム(TMG)またはトリエチルガリウム(TEG)をアンモニア(NH3)及び塩化水素(HCl)などのエッチングガスを含む混合ガスに乗せ上記MOCVD反応機内に注入する。
先ず、図3は先述した製造方法によりサファイア基板(12)の表面がHClでエッチングされ、バッファ層(14)がGaNが蒸着され窒素化した状態を示す。
後続工程においてかかるサファイア基板(14)上にGaN半導体層(16)を成長させ、本発明の窒化物半導体構造(10)を得るようになる。
Claims (5)
