Abstract:
Provided are methods for etching films comprising transition metals which help to minimize higher etch rates at the grain boundaries of polycrystalline materials. Certain methods pertain to amorphization of the polycrystalline material, other pertain to plasma treatments, and yet other pertain to the use of small doses of halide transfer agents in the etch process.

Claim (Index 10):
A method of etching a substrate, the method comprising:\n providing a polycrystalline film comprising cobalt; amorphizing the polycrystalline film by exposing the polycrystalline film to an inert plasma, reducing gas or reagent vapor at a temperature in the range of about 23\u00b0 C. to about 500\u00b0 C.; activating at least a portion of the amorphized polycrystalline film by exposing the amorphized polycrystalline film to a halide transfer agent selected from the group consisting of Cl 2 , Br 2  and I 2  to provide an activated substrate surface; and exposing the activated substrate surface to a reagent comprising a Lewis base or pi acid to provide a vapor phase coordination complex comprising one or more cobalt atoms coordinated to one or more ligands from the reagent.
