  • Patent number: 12588199
    Abstract: A non-volatile memory device includes a substrate having a cell array region and an extension region. A mold structure includes a plurality of gate electrodes and a plurality of mold insulating layers alternately stacked on the substrate such that the mold structure has a step shape that steps downwardly in the extension region in a direction away from the cell array region. A channel structure penetrates through the mold structure in the cell array region, and a cell contact structure penetrates through the mold structure in the extension region. A portion of the cell contact structure is in contact with a portion of an uppermost one of the gate electrodes. The cell contact structure includes a first portion in contact with a side surface of the uppermost one of the gate electrodes and a second portion in contact with a top surface of the uppermost one of the gate electrodes. A width of the first portion is smaller than a width of the second portion.
