Abstract
A nonvolatile memory device includes gate electrodes three dimensionally arranged on a semiconductor substrate, a semiconductor pattern extending from the semiconductor substrate and crossing sidewalls of the gate electrodes, a metal liner pattern formed between the semiconductor pattern and formed on a top surface and a bottom surface of each of the gate electrodes, and a charge storage layer formed between the semiconductor pattern and the metal liner pattern.
