摘要:
A method of inhibiting dopant diffusion in silicon using germanium is provided. Germanium is distributed in substitutional sites in a silicon lattice to form two regions of germanium interposed between a region where dopant is to be introduced and a region from which dopant is to be excluded, the two germanium regions acting as a dopant diffusion barrier.
