Threshold and DIBL Voltage vs. S-Gate Length At a Fixed Channel Length (Variable Lg/Ls Ratio)
- Comments
- Short-channel effect (DIBL) can be minimized by tuning the W-spacer thickness.
- This kind of optimization is well controllable.
- Observations
- Threshold voltage increases at increasing S-gate length at fixed Lc (decreasing Lg/Ls ratio).
- A minimum DIBL occurs about Lg/Ls = 2.
