Question:
Which of the following methods is useful for producing semiconductor grade metals of high purity?
Which of the following methods is useful for producing semiconductor grade metals of high purity?
Show Hint
For high purity metals used in semiconductors, zone refining is the method of choice due to its ability to remove impurities effectively.
Updated On: Jun 6, 2025
- Liquation
- Vapour phase refining
- Electrolytic refining
- Zone refining
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Zone refining is used to produce semiconductor-grade metals with high purity. The process involves the movement of a molten zone through the metal, which purifies the metal by segregating impurities.
