Abstract:
Methods for anisotropic dry etching of titanium-containing films used in semiconductor manufacturing have been disclosed in various embodiments. According to one embodiment, the method includes providing a substrate having a titanium-containing film thereon, and etching the titanium-containing film by a) exposing the substrate to a chlorine-containing gas to form a chlorinated layer on the substrate, b) exposing the substrate to a plasma-excited inert gas to remove the chlorinated layer, and c) repeating the exposing steps at least once.

Claim (Index 14):
The method of  claim 12 , wherein the substrate temperature is between about \u221210\u00b0 C. and about 60\u00b0 C.
