Methods of etching a carbon-rich layer on organic photoresist overlying an inorganic layer can utilize a process gas including CxHyFz, where y>=x and z>=0, and one or more optional components to generate a plasma effective to etch the carbon- rich layer with low removal of the inorganic layer. The carbon-rich layer can be removed in the same processing chamber, or alternatively can be removed in a different processing chamber, as used to remove the bulk photoresist.
