Doping is the controlled process of adding a small amount of specific impurity atoms to a pure semiconductor to modify its electrical properties. Adding donor impurities produces an N-type semiconductor, while adding acceptor impurities produces a P-type semiconductor. Doping increases the concentration of charge carriers and is fundamental to the manufacture of diodes, transistors, integrated circuits, and other semiconductor devices.
The process of adding impurities to semiconductors is called ______.
