8. Advanced MOSFET Concepts

Try these first

1. 1.

   What is the primary goal of scaling MOSFETs?

   Hint

   Think about what technologies are demanding in terms of performance.

2. 2.

   Define Short Channel Effects.

   Hint

   What happens to the control of the gate?

3. 3.

   What is the primary motivation for MOSFET scaling?

   • To reduce costs
   • To increase speed
   • To decrease size

   Hint

   What do faster devices need?

4. 4.

   True or False: Short Channel Effects worsen as device dimensions decrease.

   • True
   • False

   Hint

   Think about how control changes with size.

5. 5.

   Discuss how FinFET structures can resolve the power-density issues faced by traditional MOSFETs as they scale down.

   Hint

   Focus on how FinFET changes the contact area and field control.

6. 6.

   Evaluate the trade-offs involved in adopting high-k dielectrics over traditional materials in extreme scaling scenarios.

   Hint

   Consider the advantages of leakage reduction versus production difficulty.
