Abstract: A method of manufacturing a floating gate provides an enhancement for the efficiencies of electron charge and injection. First, a conductive pattern, constituting the floating gate is formed on a substrate. A first insulation layer is formed on a sidewall of the conductive pattern, and then a second insulation layer is formed at an upper portion of the conductive pattern in ways that increase the sharpness of an edge portion where the sidewall and upper portions of the conductive pattern meet. Therefore, electron transference from the floating ate to a control gate is facilitated.
