Webetch rate. 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. Webpdfs.semanticscholar.org
WebIn order to study the effect of CH bottom conduction on the CSL slit etching process, we skipped the ONO etching process. As shown in figure 8, the normal CH and the … WebIn the present invention an initial poly I layer etch step is not performed which avoids formation of an ONO fence that may be formed under conventional memory cell fabrication techniques. The elimination of the ONO fence prevents the formation of poly stringers which as mentioned above may short out adjacent memory cells.

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 ...
