Abstract

A method of manufacturing a semiconductor device includes forming first auxiliary patterns, alternately forming first material layers and second material layers on the sidewalls of the first auxiliary patterns so that a gap region between the first auxiliary patterns adjacent to each other is filled, removing the second material layers, and forming charge storage layers in respective regions from which the second material layers have been removed.
