Abstract: A method for fabricating a non-volatile memory device is provided to decrease a width of a charge trapping layer pattern by forming impurity regions on a substrate at both sides of a channel region. A tunnel insulation layer(102), a charge trapping layer, a blocking layer and a conductive layer are sequentially formed on a substrate(100) having a channel region(100a), and then the conductive layer is patterned to form a wordline structure(124).
