Show hintHide hint
Think about the type of carriers in n-channel.
Question 2.
What is the role of the SiO₂ layer?
Show hintHide hint
Remember its importance for preventing gate current.
3Question 3.
What type of substrate is used for an n-channel MOSFET?
- n-type

- Insulator
Show hintHide hint
Focus on the type of charge carrier it uses.
4Question 4.
True or False: The gate of a MOSFET allows current to flow through it.
- True
- False
Show hintHide hint
Think about the significance of the SiO₂ layer.
Question 5.
How would the performance of an n-channel MOSFET be affected if the substrate used was heavily doped p-type instead of a lightly doped one?
Show hintHide hint
Consider how doping concentrations affect conductivity and carrier mobility.
Question 6.
Describe a scenario where the insulation layer might fail and discuss its potential consequences on MOSFET operation.
Show hintHide hint
Think about the role of insulation in preventing current leaks.
