The diffusion of dopants into silicon via high-temperature thermal processes is one method in which silicon wafers are doped with extrinsic elements such as boron or phosphorous. During a diffusion process, extrinsic elements are introduced, commonly in a gaseous or liquid phase, at high temperature and come into contact with the silicon wafer.
