Web7.2.2 Stacked Capacitor DRAM Cell. The other mainstream DRAM family is the stacked capacitor cell. In this cell the storage capacitor is above the read/write transistor, which reduces the area available for interconnect … 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.
