Abstract:
1. A method of forming a non-volatile memory device, comprising: forming an upwardly protruding fin on a substrate; sequentially stacking a first insulation layer and a first storage pattern on a sidewall of the fin; sequentially stacking a second insulation layer and a second storage pattern on a top surface of the fin, the second insulation layer being thinner than the first insulation layer and the second storage pattern being connected to the first storage pattern; sequentially forming a blocking insulation layer and a control gate conductive layer on the substrate; and successively patterning the control gate conductive layer, the blocking insulation layer, the first storage pattern, and the second storage pattern to form a floating gate including a first storage gate and a second storage gate, a blocking insulation pattern, and a control gate electrode.
