    Abstract: In a method of manufacturing a non-volatile memory device, a first gate insulation layer and a conductive layer are formed on a substrate and then the conductive layer is partially oxidized to form an oxide layer pattern. The conductive layer is partially etched using the oxide layer pattern as an etching mask to form a floating gate electrode on the first gate insulation layer and then the silicon layer is formed on the substrate including the floating gate electrode. The silicon layer is oxidized to form a tunnel insulation layer and a second gate insulation layer on a sidewall of the floating gate electrode and on a surface portion of the substrate adjacent to the floating gate electrode and then a control gate electrode is formed on the tunnel insulation layer and the second gate insulation layer.

    Abstract: A method of forming a conductive pattern of a semiconductor device includes forming a conductive layer is on a substrate, forming a polishing protection layer on the substrate including over the conductive layer, and forming a step compensation layer on the polishing protection layer to reduce the step presented by the layer that is the polishing protection layer. The conductive layer is the exposed by removing select portions of the step compensation layer and the polishing protection layer. The conductive pattern is ultimately formed on the substrate by etching the exposed conductive layer. By planarization the intermediate structure several times once the step compensation layer is formed, a highly uniform conductive layer is sure to be formed.
