    摘要: In a method of forming a dielectric layer pattern, lower patterns are formed on a substrate. A first dielectric layer is formed on sidewalls and upper surfaces of the lower patterns and a surface of the substrate. A mask pattern is formed on the first dielectric layer to partially expose the first dielectric layer. The exposed first dielectric layer on upper surfaces and upper sidewalls of the lower patterns is partially removed and the removed first dielectric layer is deposited on surfaces of the first dielectric layer between the lower patterns, to form a second dielectric layer having a thickness greater than that of the first dielectric layer. The second dielectric layer on the sidewalls of the lower patterns and the substrate is etched to form a dielectric layer pattern. Accordingly, damage to the underlying layer may be reduced, and an unnecessary dielectric layer may be completely removed.

    摘要: Non-volatile memory devices include a tunnel insulating layer on a channel region of a substrate, a charge-trapping layer pattern on the tunnel insulating layer and a first blocking layer pattern on the charge-trapping layer pattern. Second blocking layer patterns are on the tunnel insulating layer proximate sidewalls of the charge-trapping layer pattern. The second blocking layer patterns are configured to limit lateral diffusion of electrons trapped in the charge-trapping layer pattern. A gate electrode is on the first blocking layer pattern. The second blocking layer patterns may prevent lateral diffusion of the electrons trapped in the charge-trapping layer pattern.
