  • Publication number: 20240093338
    Abstract: The present disclosure relates to a healable superplastic amorphous alloy, and specifically, to a healable superplastic amorphous alloy capable of exhibiting superplastic behavior and unique healable behavior by maximizing the complexity of the amorphous structure for an Icosahedral quenched-in nuclei quasi-crystal cluster to be formed in the amorphous matrix through the composition limitation and additive element control of Zr—Cu—Ni—Al alloy.

  • Patent number: 7800162
    Abstract: A nonvolatile memory device includes a semiconductor substrate, a tunneling insulation layer on the semiconductor substrate, a charge storage layer on the tunneling insulation layer, an inter-electrode insulation layer on the charge storage layer, and a control gate electrode on the inter-electrode insulation layer. The inter-electrode insulation layer includes a high-k dielectric layer having a dielectric constant greater than that of a silicon nitride, and an interfacial layer between the charge storage layer and the high-k dielectric layer. The interfacial layer includes a silicon oxynitride layer.

  • Patent number: 7605067
    Abstract: A method of manufacturing a non-volatile 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.
