Abstract: A method for stripping photoresist material (26) from a semiconductor substrate (16) avoids incorporation of sodium and other contaminant ions from a rework solvent. An oxygen and hydrogen plasma mixture strips the photoresist material without significant introduction of oxygen into the titanium nitride layer (24). Any oxidation of the titanium nitride is reversed by exposing the substrate to an oxygen-free, reducing plasma, such as a hydrogen-containing plasma. The titanium nitride layer is thereby much less susceptible to incorporation of contaminant ions in a subsequent cleaning with rework solvent than a layer which has been extensively oxidized during the plasma stripping process.

The plate can be used on lithographic and flexographic printing presses.
