Plasma oxidation and removal of oxidized material |
摘要 |
A method of etching a conductive layer includes converting at least a portion of the conductive layer and etching the conductive layer to substantially remove the converted portion of the conductive layer and thereby expose a remaining surface. The remaining surface has an average surface roughness of less than about 10 nm. A system for etching a conductive layer is also disclosed.
