Claim 0:
1. A method of removing a metal-containing layer from a substrate, comprising:
generating a first plasma in a process volume of a plasma chamber, wherein
a patterned device is disposed on a substrate support in the process volume, the patterned device comprising:
a patterned region and an unpatterned region;
a substrate;
a metal-containing layer formed over the substrate; and
a supporting layer disposed between the metal-containing layer and the substrate;

depositing a first film over the patterned region of the metal-containing layer with the first plasma; and
removing portions of the unpatterned region of the metal-containing layer with the first plasma without depositing the first film over the unpatterned region.
