    摘要: In a gate structure of a non-volatile memory device is formed, a tunnel insulating layer and a charge trapping layer are formed on a substrate. A composite dielectric layer is formed on the charge trapping layer and has a laminate structure in which first material layers including aluminum oxide and second material layers including hafnium oxide or zirconium oxide are alternately stacked. A conductive layer is formed on the composite dielectric layer and then a gate structure is formed by patterning the conductive layer, the composite dielectric layer, the charge trapping layer, and the tunnel insulating layer.

    摘要: Example embodiments of the present invention disclose a non-volatile semiconductor memory device, which may include a dielectric layer having an enhanced dielectric constant. A tunnel oxide layer pattern and a floating gate may be sequentially formed on a substrate. A dielectric layer pattern including metal oxide doped with Group III transition metals may be formed on the floating gate using a pulsed laser deposition process. The dielectric layer pattern having an increased dielectric constant may be formed of metal oxide doped with a transition metal such as scandium, yttrium, or lanthanum.
