    摘要: A non-volatile memory device includes a tunnel oxide layer, a charge storage layer, a blocking insulating layer, and a gate electrode that are sequentially stacked, as well as an impurity diffusion layer in an active region at both sides of the gate electrode. The gate electrode crosses active regions between device isolation layers formed in a predetermined area of a semiconductor substrate, and an edge of the charge storage layer is extended to have a protruding part that protrudes from the gate electrode. In order to form a charge storage layer having a protruding part, a stack insulating layer including first to third insulating layers is formed in an active region between the device isolation layers formed in the substrate. A plurality of gate electrodes crossing the active region are formed on the stack insulating layer, and a sidewall spacer is formed on both sidewalls of the gate electrode. Using the sidewall spacer and the gate electrode, the stack insulating layer is etched to form a charge storage layer that protrudes from the sidewall of the gate electrode.

    摘要: This disclosure provides cells of nonvolatile memory devices with floating gates and methods for fabricating the same. The cell of the nonvolatile memory device includes device isolation layers in parallel with each other on a predetermined region of a semiconductor substrate that define a plurality of active regions. Each device isolation layer has sidewalls that project over the semiconductor substrate. A plurality of word lines crosses over the device isolation layers. A tunnel oxide layer, a floating gate, a gate interlayer dielectric layer, and a control gate electrode are sequentially stacked between each active region and each word line. The floating gate and the control gate electrode have sidewalls that are self-aligned to the adjacent device isolation layers. The method for forming the self-aligned floating gate and the control gate electrode includes forming trenches in a semiconductor substrate to define a plurality of active regions and concurrently forming an oxide layer pattern, a floating gate pattern, a dielectric layer pattern and a control gate pattern that are sequentially stacked. A conductive layer is then formed on the device isolation layers and the control gate pattern. Thereafter, the conductive layer, the control gate pattern, the dielectric layer pattern, the floating gate pattern, and the oxide layer pattern are successively patterned.

    摘要: In a method of operating a nonvolatile memory device having a substrate and first through n-th word lines stacked in a direction perpendicular to the substrate, first through k-th word line voltages are applied to first through k-th word lines, respectively, which are formed adjacent to the substrate, among the first through n-th word lines. (k+1)-th through n-th word line voltages are applied to (k+1)-th through n-th word lines, respectively, which are formed above the first through k-th word lines, among the first through n-th word lines. An erase voltage, which is higher than the first through n-th word line voltages, is applied to the substrate, where n represents an integer equal to or greater than two, and k represents a positive integer smaller than n. Each of the (k+1)-th through n-th word line voltages is lower than each of the first through k-th word line voltages.
