Abstract
【解決手段】 ヘテロ構造バイポーラ・トランジスタ(HBT)及び関連する方法が開示される。一実施形態において、HBTは、基板と、基板の上の単結晶エミッタと、基板内のコレクタと、コレクタに隣接した少なくとも1つの分離領域と、各分離領域の上に延びる単結晶シリコン・ゲルマニウム(SiGe)真性ベースと、単結晶シリコン外部ベースとを含む、ヘテロ構造バイポーラ・トランジスタ(HBT)を含む。方法は、真性ベース、外部ベース及びエミッタを単結晶として形成するステップを含むことができ、外部ベース(及びエミッタ)が、多孔質シリコン上での選択的なエピタキシャル成長を用いて、自己整合された方法で形成される。その結果、幾つかのマスク・レベルを省略することができ、これを通常の処理に代わる低価格の代替物とすることができる。
