Abstract
結晶半導体基板(1)を設けるステップ;前記結晶半導体基板(1)の表面(OF)に接して、ポーラス領域(10)を設けるステップ;前記表面(OF)のポーラス領域(10)に、ドーピング物質(12)を導入するステップ;前記結晶半導体基板(1)内の前記ポーラス領域(10)を、熱によって再結晶化するステップ、ただし前記ポーラス領域のドーピングタイプおよび/またはドーピング濃度および/またはドーピング分布は、前記結晶半導体基板のドーピングタイプおよび/またはドーピング濃度および/またはドーピング分布とは異なる。さらに本発明は、このようにして製造された半導体構造体に関する。
Description
本発明は、半導体構造体の製造方法および相応する半導体構造体に関する。
請求項1による半導体構造体を製造する本発明の方法、ないし請求項11による相応の半導体構造体の利点は、例えばシリコンまたは炭化シリコンなどの結晶半導体材料からなる厚い層を、不純物原子または不純物を導入することによって特性変化させることができることである。これらの層は、多結晶として構成されていてもよい。ここでは、一方では非常に厚い複数の層を特性変化させることができる。このように層厚さが厚い場合、他の方法では効率的には製造することができない。他方では、非常に緩慢にしか拡散しない不純物原子、したがって従来技術によれば実際的な形態や方法では層に導入することができない不純物原子を導入することができる。この不純物原子は、例えばアンチモンまたはゲルマニウム、または原子直径の大きい他の原子などである。
図1a〜dは、本発明の実施例による半導体構造体の製造方法の基本製造ステップの概略断面図を示す。
図2は、本発明の実施例による半導体構造体の製造方法の基本製造ステップの経過を説明するフローチャートを示す。
図3は、公知の半導体構造体の概略断面図を示す。
図では、同じ参照符号は、同じまたは機能的に同じ構成要素を示す。
