Hot Carrier Reliability of Strained N-Mosfet with Lattice Mismatched Source/Drain Stressors
The hot carrier reliability of a novel uniaxial tensile strained n-channel transistor with silicon-carbon (Si1 -yCy) source and drain (S/D) regions is investigated for the first time. Strained n-FETs show reduced hot carrier lifetime than the control n-FETs when stressed at comparable Isub/Id ratio. Worst case hot carrier stressing is observed to occur at maximum substrate current Isub condition which leads to a higher drive current IDsat degradation as compared to the VGS = VGS stress. At nominal operating voltages, the strained n-FET is projected to have a hot carrier lifetime well exceeding the 10-years requirement, showing no severe reliability issues.
