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 1):
A method comprising:\n providing a polycrystalline film comprising a transition metal selected from the group consisting of Co, Cu, Ru, Ni, Fe, Pt, Mn and Pd, the polycrystalline film having a carbon content less than 10% on an atomic basis; exposing the polycrystalline film to a plasma at a temperature in the range of about 23\u00b0 C. to about 500\u00b0 C. to amorphize at least a portion of the polycrystalline film to provide an amorphous region; activating at least a portion of the polycrystalline film to provide an activated surface; and etching at least a portion of the activated surface by exposing the activated surface to a reagent comprising a Lewis base or pi acid.
