Silicon dioxide or silicon nitride is usually used as a masking material against HNA. As the reaction takes place, the material is removed laterally at a rate similar to the speed of etching downward. This lateral and downward etching process takes places even with isotropic dry etching which is described in the dry etch section.

Traditional non-SONOS ONO film remove method of LP device is by dry etch, but on 40nm scale, the process window is not enough due to pad oxide thinner with cell size shrink.
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 ...
