Question

How is a Zener diode fabricated?

Write two important considerations used while fabricating a Zener diode.

Answer 1

A Zener diode is fabricated by heavily doping both p and n sides of the junction

Answer 2

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.
