发明名称 Removable amorphous carbon CMP stop
摘要 A method is provided for processing a substrate including removing amorphous carbon material disposed on a low k dielectric material with minimal or reduced defect formation and minimal dielectric constant change of the low k dielectric material. In one aspect, the invention provides a method for processing a substrate including depositing at least one dielectric layer on a substrate surface, wherein the dielectric layer comprises silicon, oxygen, and carbon and has a dielectric constant of about 3 or less, forming amorphous carbon material on the at least one dielectric layer, and removing the one or more amorphous carbon layers by exposing the one or more amorphous carbon layers to a plasma of a hydrogen-containing gas.
