Description
ここで、εは歪み量、△θは<111>軸からずれた角度量を、θは<111>軸、すなわちここでは54.7°をそれぞれ表す。
図7は第1の実施形態に係る相補型MOSトランジスタ(CMOSトランジスタ)の構成を示す断面図である。Si基板1上にSiO2からなる素子分離層7を介してp型半導体層3およびn型半導体層5が形成されている。なお、基板としてSOI(Silicon On Insulator)構造の基板を用いてもよい。また、上記n型半導体層5は、SiGe層であってもよい。このときSiGe層は、高移動度を実現するための歪を含有するには、Geが原子比10%以上である必要があり、またトランジスタ特性に影響を及ぼさない欠陥量にするためには、Ge濃度は20%以下である必要がある。
第2の実施形態においては、シリサイドからなるショットキーソースドレインを有するMOSトランジスタおよびその製造工程について説明する。理解を容易にするため、第1の実施形態と同一箇所には同一の参照符号を付与し、重複する説明を省略する。
第3の実施形態においては、ストレッサーとして、p型MOSトランジスタのソース/ドレイン領域にエピタキシャル成長させたSiGe層を有する形態の半導体装置、およびその製造工程ついて説明する。理解を容易にするため、第1の実施形態と同一箇所には同一の参照符号を付与し、重複する説明を省略する。
