Description
[2]前記P 0 SiCl4 /(P 0 GaCl +P 0 SiCl4 )の値に応じて、前記ドーパントの濃度を直線状に制御する、前記[1]に記載の結晶積層構造体の製造方法。
[3]前記ドーパントの濃度を6.5×1015atoms/cm3以上2.1×1020atoms/cm3以下の範囲で制御する、前記[1]又は[2]に記載の結晶積層構造体の製造方法。
(結晶積層構造体の構成)
図1は、実施の形態に係る結晶積層構造体1の垂直断面図である。結晶積層構造体1は、Ga2O3系基板10と、Ga2O3系基板10の主面11上にエピタキシャル結晶成長により形成されたβ−Ga2O3系単結晶膜12を有する。
以下に、本実施の形態に係るβ−Ga2O3系単結晶膜12の成長に用いる気相成長装置の構造の一例について説明する。
β−Ga2O3系単結晶膜12の成長には、特願2014−088589に開示されたβ−Ga2O3系単結晶膜の成長技術を用いることができる。以下に、本実施の形態に係るβ−Ga2O3系単結晶膜12の成長工程の一例について説明する。
以下の表1〜表3に、異なる成長条件で形成した複数のβ−Ga2O3系単結晶膜12のSi濃度及びキャリア密度の測定結果を示す。
上記実施の形態によれば、HVPE法を用いてβ−Ga2O3系単結晶を成長させながらドーパントを添加することにより、MBE法やEFG法を用いる場合よりも広い範囲でβ−Ga2O3系単結晶のドーパントの濃度を制御することができる。また、イオン注入法を用いる場合のように、ドーパントの注入深さが限定されたり、イオンビームにより結晶性が劣化したりするという問題が生じない。
