1. Q: What is the difference between a diode and a transistor?
A: A diode is a two-terminal electronic component that allows current to flow in one direction only, while a transistor is a three-terminal device used for amplification and switching purposes.

2. Q: How does a semiconductor work as a conductor?
A: Semiconductors can conduct electricity under certain conditions due to their ability to change from insulating to conducting state when exposed to an electric field or light.

3. Q: What are the main challenges in fabricating high-quality silicon wafers?
A: The main challenges in fabricating high-quality silicon wafers include controlling impurities, achieving uniform crystal structure, and minimizing defects during the manufacturing process.

4. Q: Can you explain the concept of doping in semiconductors?
A: Doping involves intentionally introducing impurities into a semiconductor to alter its electrical properties, such as creating n-type or p-type regions to control conductivity.

5. Q: What are the key differences between CMOS and bipolar transistors?
A: CMOS transistors consume less power and have higher noise immunity compared to bipolar transistors, making them suitable for integrated circuits with low power requirements.

6. Q: How do photolithography techniques contribute to semiconductor manufacturing?
A: Photolithography is used to transfer patterns onto semiconductor wafers, allowing for precise etching and deposition processes to create intricate circuitry and components.

7. Q: What role does the cleanroom environment play in semiconductor fabrication?
A: Cleanrooms provide a controlled environment with low levels of airborne particles to prevent contamination during the delicate processes involved in semiconductor fabrication.

8. Q: Can you explain the concept of electron mobility in semiconductors?
A: Electron mobility refers to the speed at which electrons move through a semiconductor material under the influence of an electric field, impacting the material's overall conductivity.

9. Q: What are the primary methods for testing the quality and performance of semiconductor devices?
A: Semiconductor devices are typically tested using techniques such as electrical characterization, reliability testing, and failure analysis to ensure their functionality and durability.

10. Q: How do advancements in semiconductor technology impact the development of electronic devices?
A: Advancements in semiconductor technology enable the creation of smaller, more efficient, and higher-performing electronic devices, driving innovation across various industries.
