85nm-wide 1.5mA/µm-ION IFQW SiGe-pFET: Raised vs embedded Si0.75Ge0.25 S/D benchmarking and in-depth hole transport study

摘要

Beside the VTH-tunability, a raised SiGe S/D module offers higher LG-scalability than an embedded SiGe S/D in SiGe-IFQW pFETs. In-depth transport study of record performing 1.5mA/µm-ION strained-SiGe IFQW pFETs reveals that mobility improvement is still the key performance booster whereas LG-scaling has limited impact.
