    摘要: In non-volatile memory devices and methods of manufacturing the non-volatile memory devices, a barrier layer having an upper portion of silicon nitride and a lower portion of silicon oxide is formed on a substrate by providing a silicon oxide layer on the substrate and performing a radical nitridation process on an upper portion of the silicon oxide layer. A trapping layer including silicon nitride is formed on the barrier layer. A blocking layer and a gate electrode layer are subsequently formed on the trapping layer. The gate electrode layer, the blocking layer, the trapping layer and the barrier layer are then partially etched to provide a gate structure.

    摘要: In an embodiment, a method of manufacturing a charge-trapping dielectric and a silicon-oxide-nitride-oxide-silicon (SONOS)-type non-volatile semiconductor device includes forming the charge-trapping dielectric, and a first oxide layer including silicon oxide. A silicon nitride layer including silicon-rich nitride is formed by a cyclic chemical vapor deposition (CVD) process using a silicon source material and a nitrogen source gas. A second oxide layer is formed on the silicon nitride layer. Hence, the charge-trapping dielectric having good erase characteristics is formed. In the SONOS-type non-volatile semiconductor device including the charge-trapping dielectric, a data erase process may be stably performed.

    摘要: A semiconductor memory device includes a semiconductor substrate, a tunnel insulating layer, charge trap layer, and a blocking layer. The tunnel insulating layer is on the semiconductor substrate. The charge trap layer is on the tunnel insulating layer and includes at least one pair of a first nitride layer with a higher trap density of holes than electrons and a second nitride layer with a higher trap density of electrons than holes. The blocking layer is on the charge trap layer opposite to the tunnel insulating layer. The first nitride layer may include silicon rich nitride, which may have a ratio of silicon to nitride of greater than 1 and less than or equal to 2. The second nitride layer may include aluminum nitride which may have a hexagonal crystalline structure.
