|Abstract:||A rare-earth oxide, Gd2 O3, is evaluated for the application of the blocking layer in polysilicon-oxide-silicon nitride-oxide-silicon-type flash memory cell devices because of its high conduction-band offset and reasonably large κ value. In a Gd2 O3 Si3 N4 SiO2 dielectric stack, a monoclinic-structured Gd2 O3 shows the advantage of faster program/erase speed with comparable charge retention when compared to a conventional Al2 O3 blocking layer. Such performance makes Gd2 O3 a promising high- κ material for the blocking layer in charge-trap flash memory devices. © 2008 The Electrochemical Society.|
