28nm Gate First High-K Metal Gate (GF-HKMG) technology is analyzed for Hot-Carrier Degradation (HCD) under varying gate/drain (V

) subcomponents. The relative importance of the subcomponents is analyzed for varying T. Although pure HCD dominates under Cryo-CMOS operation, the T dependence is shown to be different for Si NMOS and SiGe PMOS FETs. Finally, the impact on the circuit (RO: Ring Oscillator) operation is analyzed. |
