MEMORY DEVICE AND MANUFACTURING METHOD THEREOF, AND SEMICONDUCTOR DEVICE

摘要

A semiconductor device disposed on a substrate is provided. The semiconductor device includes two isolation structures, a first conductive layer, a charge trapping layer, a second conductive layer and a gate dielectric layer. The two isolation structures are disposed in the substrate to define an active area. The second conductive layer across the two isolation structures is disposed on the substrate. The first conductive layer is disposed between the two isolation structures and between the second conductive layer and the substrate. The second conductive layer electrically connects with the first conductive layer. The charge trapping layer is disposed on the substrate. The gate dielectric layer is disposed between the first conductive layer and the substrate. An interface between the two isolation structures and the first conductive layer is covered by the charge trapping layer to restrain the kink effect.
