    摘要: A nonvolatile memory device includes a semiconductor substrate, a device isolation layer, a tunnel insulation layer, a floating gate, a buried floating gate, and a control gate. A trench is in the substrate that defines an active region of the substrate adjacent to the trench. A device isolation layer is on the substrate along the trench. A tunnel insulation layer is on the active region of the substrate. A floating gate is on the tunnel insulation layer opposite to the active region of the substrate. A buried floating gate is on the device isolation layer in the trench. An intergate dielectric layer is on and extends across the floating gate and the buried floating gate. A control gate is on the intergate dielectric layer and extends across the floating gate and the buried floating gate.

    摘要: Methods of forming nonvolatile memory devices include forming first and second floating gate electrodes of first and second nonvolatile memory cells, respectively, at side-by-side locations on a substrate. The substrate is selectively etched to define a trench therein extending between the first and second floating gate electrodes. The trench is at least partially filled with a first electrical insulation pattern. An inorganic polysilazane-type spin-on-glass (SOG) layer is conformally deposited on the first and second floating gate electrodes and on the first electrical insulation pattern and then partially removed.
