    摘要: Semiconductor devices, and methods of fabricating the same, include forming a trench between a plurality of patterns on a substrate to be adjacent to each other, forming a first sacrificial layer in the trench, forming a first porous insulation layer having a plurality of pores on the plurality of patterns and on the first sacrificial layer, and removing the first sacrificial layer through the plurality of pores of the first porous insulation layer to form a first air gap between the plurality of patterns and under the first porous insulation layer.

    摘要: A tunnel insulating layer and a charge storage layer are sequentially stacked on a substrate. A recess region penetrates the charge storage layer, the tunnel insulating layer and a portion of the substrate. The recess region is defined by a bottom surface and a side surface extending from the bottom surface. A first dielectric pattern includes a bottom portion covering the bottom surface and inner walls extending from the bottom portion and covering a portion of the side surface of the recess region. A second dielectric pattern is in the recess region between the inner walls of the first dielectric pattern, and the second dielectric pattern enclosing an air gap. The air gap that is enclosed by the second dielectric pattern may extend through a major portion of the second dielectric pattern in a direction away from the bottom surface of the recess region.
