Zusammenfassung:	A method for etching a metal containing material is provided. The metal containing material is exposed to a halogen containing fluid or plasma to convert at least some of the metal containing material into a metal halide material. The metal halide material is exposed to a ligand containing fluid or plasma, wherein at least some of the metal halide material is formed into a metal halide ligand complex. At least some of the metal halide ligand complex is vaporized.
