Description
本明細書で使用される、用語「III−V族」は少なくとも1つのIII族元素と少なくとも1つのV族元素を含む化合物半導体を意味する。例えば、III−V族半導体は、III族窒化物半導体の形を取り得る。「III族窒化物」又は「III−N」は窒素とアルミニウム(Al)、ガリウム(Ga)、インジウム(In)及びボロン(B)などの少なくとも1つのIII族元素を含む化合物半導体を意味し、例えば窒化アルミニウムガリウム(AlxGa(1-x)N、窒化インジウムガリウムInyGa(1-y)N、窒化アルミニウムインジウムガリウムAlxInyGa(1-x-y)N、砒化リン化窒化ガリウム(GaAsaPbN(1-a-b))、砒化リン化窒化アルミニウムインジウムガリウム(AlxInyGa(1-x-y)AsaPbN(1-a-b))などの合金を含むが、これらに限定されない。また、III族窒化物は一般に、Ga極性、N極性、半極性又は非極性結晶方位などの任意の極性を有するが、これらに限定されない。また、III族窒化物材料は、ウルツ鉱型、閃亜鉛鉱型、あるいは混合ポリタイプ(結晶多形)のいずれかを含むことができ、単結晶又はモノクリスタル、多結晶、または非結晶の結晶構造を含むことができる。本明細書で使用される、「窒化ガリウム」、「GaN」はIII族窒化物化合物半導体を意味し、III族元素は若干量又は相当量のガリウムを含むが、ガリウムに加えて他のIII族元素も含むことができる。また、III−V族又はGaNトランジスタはIII−V族又はGaNトランジスタを低電圧IV族トランジスタとカスコード接続することによって形成される複合高電圧エンハンスメントモードトランジスタを指す。
