Abstract

This paper reports on the successful integration of truly diffusion-less (less-than-650°C) junction formation by SPER in pMOSFETs in combination with Ni-FUSI gates for the first time. The obtained drive currents are 355 μA/μm for an off-state of 10 pA/μm at Vdd=-1.2V and 1.4nm EOT SiON. We demonstrate that the gate de-activation problem associated with SPER is effectively solved by the use of the FUSI gate electrode. Super halo profiles are obtained with SPER, which opens up the halo design space for accurate SCE control. The junction leakage is greatly reduced by engineering the damage region away from the junction depletion region.
