    Abstract: A method of manufacturing a non-volatie memory device includes forming a tunnel insulating layer on a substrate, forming a conductive pattern on the tunnel insulating layer, forming a lower dielectric layer on the conductive pattern, performing a first heat treatment process to density the lower dielectric layer, and forming a middle dielectric layer having an energy band gap smaller than that of the lower dielectric layer on the first heat-treated lower dielectric layer. The method further includes forming an upper dielectric layer including a material substantially identical to that of the lower dielectric layer on the middle dielectric layer, performing a second heat treatment process to densify the middle dielectric layer and the upper dielectric layer and forming a conductive layer on the second heat-treated upper dielectric layer.

    Abstract: Disclosed is a method for forming metal oxide dielectric layers, more particularly HfO2 dielectric layers, using an atomic layer deposition (ALD) method in which a series of thin intermediate layers are formed and treated with one or more oxidizers and nitrogents before the next intermediate layer is formed on the substrate. The intermediate oxidation treatments reduce the number of organic contaminants incorporated into the metal oxide layer from the organometallic precursors to produce a dielectric layer having improved current leakage characteristics. The dielectric layers formed in this manner remain susceptible to crystallization if exposed to temperatures much above 550° C., so subsequent semiconductor manufacturing processes should be modified or eliminated to avoid such temperatures or limit the duration at such temperatures to maintain the performance of the dielectric materials.

    Abstract: A method for manufacturing a semiconductor device employing a dielectric layer for forming a conductive layer into a three-dimensional shape. The dielectric layer is formed on a substrate in such a manner as to provide an intrinsic etch rate within the layer which increases in the direction of the thickness or depth of the dielectric layer. This variable intrinsic etch rate within the dielectric layer is achieved by changing one of a plurality of deposition variables. Once formed, the dielectric layer is selectively etched to form a through hole to contact a conductive area underlying the dielectric layer. A conductive layer is formed in the through hole, which may be a storage node of a capacitor.
