Web1 mei 2008 · To conclude, carbon hard mask offers new possibilities for improving lithography resolution. The use of such a mask in association with a capping layer suppresses resist thickness limitations, which allows us to pattern ultra thin resist films. Furthermore, this combination of material enables the transfer and integration of sub 30 … 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…
