ABSTRACT:
A zener diode adapted for mounting in a double plug package has a shallow junction region formed by a controlled diffusion of a first type of semiconductivity impurity into a semiconductive material having a second type of semiconductivity to establish a desired zener voltage. A region of deep diffusion of first type of semiconductivity impurity is formed adjacent to and in contact with the shallow junction region and a metal contact is connected to the deep diffused region.
