8.2. MOSFET Scaling – Definition and Motivation

Try these first

1. 1.

   What does MOSFET scaling involve?

   Hint

   Think about what scaling means in a broader sense.

2. 2.

   List one goal of MOSFET scaling.

   Hint

   Remember the benefits we discussed.

3. 3.

   What is one goal of MOSFET scaling?

   • Increase size
   • Increase power consumption
   • Increase transistor density

   Hint

   Think about how we optimize chip space.

4. 4.

   Increasing transistor density can lead to what benefit?

   • True
   • False

   Hint

   More transistors mean more processing power.

5. 5.

   Design an approach to mitigate short-channel effects when scaling a MOSFET below 20 nm.

   Hint

   Think about geometrical designs that allow better control over the channel.

6. 6.

   Assess the impact of using high-k dielectric materials in MOSFETs on power efficiency.

   Hint

   Consider how changes in materials affect electrical characteristics.
