  • Semiconductor device including insulating layers and method of forming the same
    Patent number: 10325922
    Abstract: A semiconductor device includes a substrate, a stacked structure of insulating layers and gate electrodes alternately and repeatedly stacked on the substrate, and a pillar passing through the stacked-layer structure. The insulating layers include lower insulating layers, intermediate insulating layers disposed on the lower insulating layers, and upper insulating layers disposed on the intermediate insulating layers. The lower insulating layers have a hardness less than that of the intermediate insulating layers, and the upper insulating layers have a hardness greater than that of the intermediate insulating layers.
    Type: Grant
