VERTICAL NON-VOLATILE MEMORY DEVICES AND METHODS FOR MANUFACTURING THE SAME

A vertical non-volatile memory device may include a mold structure including first and second insulation patterns and a first gate electrode, a semiconductor pattern extending through the mold structure in a first direction, a first charge insulation layer between the first insulation pattern and the semiconductor pattern, a second charge insulation layer spaced apart from the first charge insulation layer and between the second insulation pattern and the semiconductor pattern, a charge storage layer between the first and second charge insulation layers and between the first gate electrode and the semiconductor pattern, and a first blocking insulation layer between the first gate electrode and the charge storage layer, and a first length in the first direction of the first gate electrode is shorter than a second length in the first direction of a first surface of the charge storage layer which is in contact with the first blocking insulation layer.
