Abstract
Provided is a memory device including a plurality of stack structures disposed on a substrate; and a dielectric layer. Each stack structure includes a first conductive layer, a second conductive layer, an inter-gate dielectric layer, a metal silicide layer, and a barrier layer. The second conductive layer is disposed on the first conductive layer. The inter-gate dielectric layer is disposed between the first and second conductive layers. The metal silicide layer is disposed on the second conductive layer. The barrier layer is disposed between the metal silicide layer and the second conductive layer. The dielectric layer laterally surrounds a lower portion of the plurality of stack structures to expose a portion of the metal silicide layer of the plurality of stack structures.
