(a) Electrons or holes arc moved between two contacts by drift current in a Field Effect Transistor (FED. A voltage applied at the gate controls the amount of flow. Explain the operation of pMOS using a diagram that depicts the flow of holes and electrons.
(c) There are a few design methods used in the creation of an integrated circuit. In your opinion, which design method is best for designing the circuit. Discuss why semiconductor materials are widely used in integrated circuit development.
