Description
"An efficient method for cleaning Ge(100) surface" by K. Prabhakarana et al., Surface Science Vol. 316, pp.L1031-L1033. "Carbon contamination free Ge(100) surface cleaning for MBE" by H. Okumura et al., Applied Surface Science.
第1の実施形態では、ゲルマニウム・オン・インシュレーター基板(以下GOI基板と称する)上にGe層をエピタキシャル成長させる例について述べる。ここで、GOI基板は素子形成層であるGe層が高キャリア移動度を持ち、GOI構造をとることにより短チャネル効果に強く、超高速微細デバイス製作用基板として非常に有望であることを注記しておく。
前記第1の実施形態における基板を、GOI100基板からバルクGe基板201に変更しても、第1の実施形態と同様の効果が得られる。図2(c)はGe膜成膜前のGe基板201の断面図であり、図2(d)はGe膜202成膜後の基板の断面図を示す。基板の洗浄・成膜プロセスは、基板材料を除けば、図1と全く同じとなるので、重複する説明を省略する。
第3の実施形態では、シリコンゲルマニウム・オン・インシュレーター基板(以下SGOI基板と称する)表面上に、ひずみGeチャネル層を成長させる例を説明する。プロセスフローチャートを図9に示す。また、図10(a)にGe膜成膜前、図10(b)に成膜後の基板の断面図を示す。
前記第3の実施形態における基板を、SGOI基板300からバルクSiGe基板400(Si基板401上にSiGe層402を成長させたもの)に変更しても、第3の実施形態と同様の効果が得られる。図10(c)はGe膜成膜404前の基板400の断面図であり、図10(d)はGe膜404成膜後の基板の断面図を示す。基板の洗浄・成膜プロセスは、基板材料を除けば、図9と全く同じとなるので、重複する説明を省略する。
第1および第2の実施形態において、洗浄後成長する層をGe層ではなく、SiGe層に変更しても、第1および第2の実施形態と同様の成長前洗浄を施すことで、高品質なSiGe成長層が得られる。
第3及び第4の実施形態において、洗浄後成長する層をGe層ではなく、SiGe層に変更しても、第3及び第4の実施形態と同様の成長前洗浄を施すことで、高品質なSiGe成長層が得られる。
第1及び第2の実施形態において、洗浄後成長する層をGe層ではなく、Si層に変更しても、第1及び第2の実施形態と同様の成長前洗浄を施すことで、高品質なSi層が得られる。
第3及び第4の実施形態において、洗浄後成長する層をGe層ではなく、Si層に変更しても、第3及び第4の実施形態と同様の成長前洗浄を施すことで、高品質なSi層が得られる。
