A hardmask is a material used in semiconductor processing as an etch mask instead of a polymer or other organic "soft" resist material. The idea is that polymers tend to be etched easily by oxygen, fluorine, chlorine or other reactive gases to the extent that a pattern defined using a polymeric mask is rapidly degraded during plasma etching.
