Web11 de out. de 2001 · ONO etch time limited by fence leakage (too short ONO etch) and attack of STI in. slits (too long ONO etch). 100% yield. regarding FG to FG leakage is achieved on. a 1Mb test structure. Reference ... 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 ...
