摘要： A method for cleaning a processing chamber that includes heating an inner surface of the processing chamber to a first temperature. The first temperature can be sufficient to cause a first species to become volatile. The first species can be one of several species deposited on the inner surface. A cleaning chemistry is injected into the processing chamber. The cleaning chemistry can be reactive with a second one of the species to convert the second species to the first species. The volatilized first species can also be output from the processing chamber. A system for cleaning the process chamber is also described.

摘要： A method of cleaning a bevel edge of a semiconductor substrate is provided. A semiconductor substrate is placed on a substrate support in a reaction chamber of a plasma processing apparatus. The substrate has a dielectric layer overlying a top surface and a bevel edge of the substrate, the layer extending above and below an apex of the bevel edge.

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.
