    摘要: Provided is a nonvolatile memory device having a three dimensional structure. The nonvolatile memory device may include cell arrays having a plurality of conductive patterns having a line shape three dimensionally arranged on a semiconductor substrate, the cell arrays being separated from one another; semiconductor patterns extending from the semiconductor substrate to cross sidewalls of the conductive patterns; common source regions provided in the semiconductor substrate under a lower portion of the semiconductor patterns in a direction in which the conductive patterns extend; a first impurity region provided in the semiconductor substrate so that the first impurity region extends in a direction crossing the conductive patterns to electrically connect the common source regions; and a first contact hole exposing a portion of the first impurity region between the separated cell arrays.
