प्रश्न
How is a Zener diode fabricated?
Write two important considerations used while fabricating a Zener diode.
उत्तर १
A Zener diode is fabricated by heavily doping both p and n sides of the junction
उत्तर २
Two important considerations while fabricating a Zener diode are as follows:
(i) The Zener diode should be fabricated by heavily doping both p and n junctions.
(ii) Proper wafer-handling devices must be used to avoid contamination, which may affect the quality and stability of the diode.
