Abstract
A semiconductor memory device includes a plurality of nanowires vertically stacked over a substrate, and a plurality of memory films wrapping around the plurality of nanowires, respectively. Each of the memory films includes a first oxide layer, a nitride layer and a second oxide layer sequentially formed over the corresponding nanowire. The semiconductor memory device also includes a gate electrode layer surrounding the plurality of memory films, and an isolation structure encapsulating the gate electrode layer. The isolation structure is in direct contact with the gate electrode layer and the nitride layers of the memory films.
