Nickel silicide nanocrystals embedded in SiO2 and HfO2 for nonvolatile memory application
In this study, a nonvolatile memory device with NiSi2 nanocrystals embedded in the SiO2 and HfO2 layer has been fabricated. A significant memory effect is observed during the characterization of the electrical properties. When a low operating voltage, 4 V, is applied, a significant threshold voltage shift of 1.3 V, is observed. The processing of this structure is compatible with the current manufacturing technology of semiconductor industry. (C) 2007 Published by Elsevier B.V.
