Description
りGa2O3層の品質を高くする。しかしながら、酸化膜のバルクトラップ密度が依然として許容できないほどに高く、非常に大きなリーク電流が観察される。
本発明の別の実施形態において、GaAsをベースとする支持半導体構造は、少なくとも一部が完全な半導体装置のようなGaAsをベースとするヘテロ構造である。本発明の幾つかの実施形態では、一部が完全な半導体装置は、例えば金属−酸化膜電界効果トランジスタ、ヘテロ接合バイポーラトランジスタ、または半導体レーザとすることができる。
界面またはGa−Gd酸化膜/GaAs界面のいずれかにより構成されてきた。
イス技術及び特定の製造技術に都合の良いシーケンスで形成することができる。一般的に、基板311はGaAsをベースとする材料であり、そして層312,313及び314に使用する材料の全ては結晶結合するように同様の材料系により形成される。これは、この技術分野では公知のように、種々の層を順次標準の成長チャンバーでエピタキシャル成長させることにより実現する。
