  • SEMICONDUCTOR MEMORY DEVICE AND METHOD OF FABRICATING THE SAME
    Publication number: 20240251553
    Abstract: A semiconductor memory device includes a stack structure on a substrate, extending in a first direction, and including gate electrode layers and insulating layers stacked alternately with each other, a vertical structure including a vertical channel film extending in a second direction crossing the first direction and a channel insulating film disposed on the vertical channel film and having first areas adjacent to the insulating layers and second areas adjacent to the gate electrode layers, and a high-k film on the channel insulating film. The high-k film includes a first high-k metal oxide film between the first areas and the insulating layers and in contact with the first areas and a second high-k metal oxide film between the second areas and the gate electrode layers and in contact with the second areas, and the first and second high-k metal oxide films include different metal materials.

  • ALUMINUM NITRIDE SINTERED BODY AND MEMBER FOR SEMICONDUCTOR MANUFACUTING APPARATUS COMPRISING SAME
    Publication number: 20230024625
    Abstract: An aluminum nitride sintered body contains 1 to 5% by weight of yttrium oxide (Y2O3), 10 to 100 ppm by weight of titanium (Ti), and the balance being aluminum nitride (AlN). Accordingly, a volume resistance value and thermal conductivity at a high temperature are improved, and the generation of impurities during a semiconductor manufacturing process can be suppressed.
