发明名称 Enhanced stripping of low-K films using downstream gas mixing
摘要 The present invention pertains to methods for removing unwanted material from a work piece. More specifically, the invention pertains to stripping photo-resist material and removing etch-related residues from a semiconductor wafer during semiconductor manufacturing. Methods involve implementing a hydrogen plasma operation with downstream mixing with an inert gas. The invention is effective at stripping photo-resist and removing residues from low-k dielectric material used in Damascene devices.
