    摘要: Methods of manufacturing vertical semiconductor devices may include forming a mold structure including sacrificial layers and insulating interlayers with a first opening formed therethrough. The sacrificial layers and the insulating interlayers may be stacked repeatedly and alternately on a substrate. The first opening may expose the substrate. Blocking layers may be formed by oxidizing portions of the sacrificial layers exposed by the first opening. A first semiconductor layer pattern, a charge trapping layer pattern and a tunnel insulation layer pattern, respectively, may be formed on the sidewall of the first opening. A second semiconductor layer may be formed on the first polysilicon layer pattern and the bottom of the first opening. The sacrificial layers and the insulating interlayers may be partially removed to form a second opening. The sacrificial layers may be removed to form grooves between the insulating interlayers. Control gate electrodes may be formed in the grooves.

    摘要: A method of forming self-aligned contact holes in an oxide layer to expose a semiconductor substrate between adjacent gate lines. The gate lines are formed such that a spacing between adjacent gate lines in the storage node contact region is equal to or greater than a spacing between adjacent gate lines in the bit line contact region. An insulating layer is deposited on the gate line to fill spaces between the gate lines. Self-aligned contact holes are formed in the insulating layer, using a photolithographic process. As a result, storage node contact hole not-opening phenomenon and bit line contact shoulder over-etching phenomenon can be avoided.
