In a grown junction type construction, the method used form a junction...
The grown junction may be formed by suddenly varying the rate of pulling the seed crystal from the melt. This method is based on the fact that proportion in which N and P type impurities crystallise i.e.., enter the grown crystal depends on the rate of pulling.

Understanding Junction Transistor Construction
In junction transistor construction, particularly in a grown junction type, the method of formation is crucial for the device's performance. The correct answer to the question regarding the method used is:
Speed Variation Method (Option C)
What is the Speed Variation Method?
- This technique involves controlling the growth rates of different semiconductor materials during the fabrication process.
- By varying the speed at which these materials are grown, distinct junctions can be formed with precise doping profiles, allowing for better electrical characteristics.
Advantages of Speed Variation Method
- Precision Control: This method allows for fine control over the junction's properties, which is essential for high-performance transistors.
- Improved Performance: Transistors produced with this method typically exhibit enhanced speed and efficiency, making them suitable for high-frequency applications.
- Quality of Junction: The quality of the junction is superior due to the controlled environment, reducing defects and improving reliability.
Comparison with Other Methods
- Alloy Type Diffusion: This method usually results in broader junctions and can introduce more defects.
- Mesa Type: While this method is effective, it may not provide the same level of precision in doping profiles as the speed variation method.
- Fused Junction Type: This method is less common and typically not preferred for high-performance junction transistors.
In conclusion, the speed variation method is a sophisticated approach to forming junctions in transistors, leading to enhanced performance and reliability, making it the preferred choice in many applications.
