Are you preparing for Semiconductor interview? Semiconductor is a solid material which regulates the flow of current in metal, other devices. Semiconductor is used in developing electronic chips, computer devices. It is mixture of germanium, silicon and other components. There are two types of semiconductor depending on its conductance and inductance. Candidates are supposed to have basic knowledge on the Semiconductor. Many companies are in need of such people. There is less number of people who are skilled in core concepts. There is huge demand for this technology in the market. Opportunities are everywhere for this technology. Good knowledge on how the process is done will fetch you the job. Wisdomjobs framed Semiconductor interview questions and answers to make it easier for your interview preparation.

Question 8. What Type Of Semiconductor Do You Get If You Dope It With Boron?
Answer :
A p-type semiconductor.
Question 9. What Is A Iii-v Semiconductor?
Answer :
A semiconductor made from elements in columns III and V of the periodic table.
Question 10. What Mathematical Formula Most Accurately Predicts The Fermi Level Of A Semiconductor?
Answer :
Fermi-Dirac distribution.
Question 11. What Are The Four Terminals Of An Fet Transistor?
Answer :

Answer :
Valence and conduction
Answer :
To improve breakdown voltage.
Question 18. What Is A Semiconductor?
Answer :
The combination of a conductive material, and an insulator.
Question 19. What Does 'doping' Do?
Answer :
Changes a semiconductor's behavior.
Question 20. When Silicon Has Been Doped, What Does This Mean?
Answer :
Impurities have been added that alter its electronic properties in a controllable way.
Answer :
The process of deliberately adding impurities to affect conductivity is called Doping.
Question 22. Why Are Semiconductors Important?
Answer :
They successfully replaced vacuum tubes as the primary way to compute data.
Question 23. What Does Led Stand For?
Answer :
Light Emitting Diode
Question 24. What Does Mosfet Stand For?
Answer :
