This work presents the performance and transport characteristics of vertically stacked p-MOSFET SOI nanowires (NWs) with inner spacers and epitaxial growth of SiGe raised source/drain. Electrical characterization is performed for NWs with [110] and [100] channel orientations, as a function of both fin width (W$_{FIN}$) and channel length (L). Results show a good electrostatic control and reduced short channel effects (SCE) down to 15nm gate length. Improved effective mobility is obtained for [110]-oriented NWs due to higher sidewall mobility contribution.
