Transistor from 1965

The German alloy transistor is a low-alloyed doped germanium alloyed baseplate with a temperature of approximately 550 ° C on opposite sides of the metal balls. Fusion of metal changes semiconductor type to the opposite, creating emitter and collector areas. Types

The p-n-p transistor was formed by infiltration of gallium-induced beads into a semiconductor type n.
