Thin-source concentration dependent diffusion
… sectioning. The l6 2 pre-diffusion surface concentration was approximately 3xlO(Ca)-atoms!cm, which, for an average penetration depth of IOOum-300um, produces a maximum (post-diffusion) impurity concentration comparable to or greater than the intrinsic cation vacancy concentration. …
