发明名称 Method of damaged low-k dielectric film layer removal
摘要 An apparatus, system and method for removing a damaged material from a low-k dielectric film layer include identifying a control chemistry, the control chemistry configured to selectively remove the damaged material from the low-k dielectric film layer, the damaged material being in a region where a feature was formed through the low-k dielectric film layer; establishing a plurality of process parameters characterizing aspects of the damaged material to be removed and applying the control chemistry to the low-k dielectric film layer, the application of the control chemistry being defined based on the established process parameters of the damaged material, such that the damaged material is substantially removed from the areas around the feature and the areas around the feature are substantially defined by low-k characteristics of the low-k dielectric film layer.
