    摘要: Methods and apparatus for remedying arc-related damage to the substrate during plasma bevel etching. A plasma shield is disposed above the substrate to prevent plasma, which is generated in between two annular grounded plates, from reaching the exposed metallization on the substrate. Additionally or alternatively, a carbon-free fluorinated process source gas may be employed and/or the RF bias power may be ramped up gradually during plasma generation to alleviate arc-related damage during bevel etching. Also additionally or alternatively, helium and/or hydrogen may be added to the process source gas to alleviate arc-related damage during bevel etching.
