Abstract
A method of selectively forming a germanium structure within semiconductor manufacturing processes removes the native oxide from a nitride surface in a chemical oxide removal (COR) process and then exposes the heated nitride and oxide surface to a heated germanium containing gas to selectively form germanium only on the nitride surface but not the oxide surface.
