8.3. Types of Scaling

Try these first

1. 1.

   What is Constant Field Scaling?

   Hint

   Look for details in the definition of scaling.

2. 2.

   How does Constant Voltage Scaling differ from Constant Field Scaling?

   Hint

   Think about the effects on dimensions versus voltage.

3. 3.

   What does Constant Field Scaling do?

   • Only scales dimensions
   • Keeps electric field constant
   • Varies voltage only

   Hint

   Focus on how the electric field is treated in this approach.

4. 4.

   True or False: Constant Voltage Scaling leads to increased electric fields.

   • True
   • False

   Hint

   Think about the relationship between constant voltage and dimension changes.

5. 5.

   Design a hypothetical transistor that utilizes both Constant Voltage Scaling and Generalized Scaling, discussing how you would balance the benefits and challenges of both.

   Hint

   Consider how both approaches can complement each other.

6. 6.

   Evaluate the potential short-channel effects on a Constant Voltage scaled MOSFET as dimensions decrease to near atomic levels. What strategies would you implement to mitigate these effects?

   Hint

   Think about innovative materials and structures in advanced MOSFET design.
