It is shown that (a) the influence of the sidewall changes the orientation dependence of the longchannel mobility in planar bulk pMOSFETs and (b) that this orientation dependence further changes in short-channel devices with (110)/⟨100⟩ having the hightest on-current in the absence of stress. The strongest performance is obtained for uniaxial compressive stress in ⟨111⟩ channel direction, while high uniaxial tensile stress in ⟨100⟩ direction enables only a modest gain.engProceedings paper10.1109/sispad66650.2025.11186385WOS:001846246700085MOSFETSALLOYS
