WebSecond, the ONO etch process must preserve the intrinsic surface quality of the resulting silicon surface. In general, the present invention discloses an etch process intended to etch the ONO dielectric layer 10, and to overetch into the silicon substrate 11 with a series of progressively lower power levels to reduce damage to the silicon substrate 11. WebView history. 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 ... red cliff properties durango
