WebWet chemical etching is the most common strategy for glass microfabrication. In most cases, hydrofluoric acid (HF) is used as the main etchant for any type of silicate glass. Some … WebThrough this work, we present a core leakage failure mechanism in our 90 nm high density memory products which was found to be related to etch process loading sensitivity to high density. Process optimization was done to fix the problem while maintaining sufficient etch margin against stringers.

ONO spacer etch process to reduce dark current

WebA number of phenomena was found to produce undesirable etching profiles, including reflection of ions on sidewalls, 1,2 poor lithography, 3 poor selectivity to resist, 4 and … 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 ... graphene marketplace

"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. " - Ono etch
