Diffusion of dopants in silicon - Iowa State University
tuttle.merc.iastate.eduSolid-solubility limit In principle, the surface concentration that shows up in the diffusion expression could be controlled by changing the flow of a gaseous source of the dopant. (More about this later.) In practice, however, N s will be determined by the “solid solubility limit” of the dopant in the silicon. This is the thermodynamic ...
