Abstract

　ｍ面のような非極性面の窒化物基体上に窒化物半導体を結晶成長させるに際し、窒化物半導体層を成長させる前の比較的高温領域での昇温過程におけるメインフローを構成するガス（基体の窒化物主面が暴露される雰囲気）、第１および第２の窒化物半導体層成長完了までのメインフローを構成するガス（基体の窒化物主面が暴露される雰囲気）を、窒化物に対してエッチング効果のないものを主とし、かつ、窒化物半導体層の成長開始時にはＳｉ源を供給しないこととした。このため、エピタキシャル基体の窒化物表面近傍からの窒素原子の脱離が生じず、エピタキシャル膜への欠陥導入が抑制される。また、平坦性に優れた表面モルフォロジを有するエピタキシャル成長が可能となる。
