    摘要: A semiconductor device includes a memory cell structure on a substrate, and a dummy structure on a side of the memory cell structure. The memory cell structure includes a memory stack structure including interlayer insulating layers and gate electrodes alternately stacked on the substrate, channel structures penetrating through the memory stack structure and contacting the substrate, and first separation structures penetrating through the memory stack structure and extending in the first direction to separate the gate electrodes from each other in a second direction. The dummy structure includes dummy stack structures spaced apart from the memory stack structure and including first insulating layers and dummy gate electrodes alternately stacked, dummy channel structures penetrating through the dummy stack structures, and second separation structures penetrating through the dummy stack structures and extending in the second direction to separate the dummy gate electrodes from each other in the first direction.

    摘要: A semiconductor manufacturing apparatus includes a chamber that includes a station in which a substrate is provided, a substrate holder that is in the station and receives the substrate, and lower showerheads below the substrate holder, the lower showerheads including an isotropic showerhead having first nozzle holes that isotropically provide a first reaction gas on a bottom surface of the substrate, and a striped showerhead having striped nozzle regions and striped blank regions between the striped nozzle regions, the striped nozzle regions having second nozzle holes that non-isotropically provide a second reaction gas on the bottom surface of the substrate.
