Hard mask materials can be categorized into organic and … A hardmask is a material used in semiconductor processing as an etch mask instead of a polymer or other organic "soft" resist material. Hardmasks are necessary when the material being etched is itself an organic polymer. Anything used to etch this material will also etch the photoresist being used to define its patterning since that is also an organic polymer. This arises, for instance, in the patterning of low-κ dielectric insulatio…
