Ono etch
Web1 de out. de 2009 · Fig. 3 shows oxide replicas of the specimens after a 100-cycles AC etch. It is apparent that the density and size of the pit clusters depend on H 2 SO 4 concentration in the etchant. With increasing H 2 SO 4 concentration, clustering of pits is favored. The higher the concentration of H 2 SO 4, the larger the cluster size and the … WebCookie Duration Description; cookielawinfo-checkbox-analytics: 11 months: This cookie is set by GDPR Cookie Consent plugin.

WebThis paper applies a new integration flow study of ONO film uniformity and silicon recess improvement for 2T-SONOS Flash on 40nm Tech. 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. 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.
