1 Digital Integrated Circuits 10: Short-Channel MOSFETs
Revision

2 Short Channel MOS Physics
Short-Channel Effect Narrow-Channel Effect Drain-Induced Barrier Lowering Channel Length Modulation Field-Dependent Mobility and Velocity Saturation

3 Short-Channel Effect (SCE)

4 Drain-Induced Barrier Lowering (DIBL)
The subthreshold current becomes a strong function of the drain-to-source bias – an indicator of short-channel behavior.

5 Channel Length Modulation (CLM)
linear saturation

6 Carrier Velocity Saturation

7 Short-Channel MOS Operation
linear saturation

8 Long- and Short-Channel n-MOSFETS
The long-channel equations overestimate the drain current and the drain-to-source voltage for saturation.

9 Long- and Short-Channel p-MOSFETS
Short channel equations should be used for L < 0.5 mm.
