摘要: A process for forming a small grain structure in a material within a semiconductor device near the interface of an adjacent dissimilar material, to result in a highly diffusive grain structure. The highly diffusive grain structure formed within one material enhances diffusion of a dopant impurity, and provides for improved dopant control in an adjacent dissimilar material.
