Question

what is a metallurgical junction?

Answer 1

Answer:

The "metallurgical junction" is the transition location from the p-doped region to the n-doped region of a semiconductor. As such a junction is mostly produced by a heat driven diffusion of dopants into the semiconductor, which is a metallurgical process, it is called a "metallurgical junction". This is sometimes differentiated from the electrical junction which involves space charge (depletion) regions around the metallurgical junction.
