    摘要: In one embodiment, the semiconductor memory device includes a semiconductor substrate having projecting portions, a tunnel insulation layer formed over at least one of the projecting semiconductor substrate portions, and a floating gate structure disposed over the tunnel insulation layer. An upper portion of the floating gate structure is wider than a lower portion of the floating gate structure, and the lower portion of the floating gate structure has a width less than a width of the tunnel insulating layer. First insulation layer portions are formed in the semiconductor substrate and project from the semiconductor substrate such that the floating gate structure is disposed between the projecting first insulation layer portions. A dielectric layer is formed over the first insulation layer portions and the floating gate structure, and a control gate is formed over the dielectric layer.

    摘要: In a non-volatile memory device, active fin structures extending in a first direction may be formed on a substrate. A tunnel insulating layer may be formed on surfaces of the active fin structures and bottom surfaces of trenches that may be defined by the active fin structures. A charge trapping layer and a blocking layer may be sequentially formed on the tunnel insulating layer. A gate electrode structure may include first portions disposed over top surfaces of the active fin structures and second portions vertically spaced apart from portions of the charge trapping layer that may be disposed over the bottom surfaces of the trenches, and may extend in a second direction substantially perpendicular to the first direction. Thus, lateral electron diffusion may be reduced in the charge trapping layer, and thereby the data retention performance and/or reliability of the non-volatile memory device may be improved.
