How to dope silicon? Boron, arsenic, phosphorus, and occasionally gallium are used to dope silicon. Boron is the p-type dopant of choice for silicon integrated circuit production because it diffuses at a rate that makes junction depths easily controllable.
What does it mean to dope the silicon? By doping the silicon, you change its electrical properties: Wherever the dopant is added, the silicon becomes more conductive. Another way to dope semiconductors is to use materials such as boron, in which each atom has one fewer valence electron than does a silicon atom.
