Abstract: Pure germanium (Ge) source and drain (S/D) stressors are integrated with ultrathin-body (UTB) and nanowire field-effect transistors (FETs). This is the first report of the integration of Ge S/D stressors in FETs. The Ge S/D stressors induce a large compressive stress in the channel, resulting in up to 80% IDsat enhancement in UTB-FETs. Electrical results further show that increased substrate compliance effects allow nanowire FETs to achieve even higher levels (96%) of strain-induced enhancement. © 2008 IEEE.
