摘要:
An EEPROM includes a device isolation layer for defining a plurality of active regions, a pair of control gates extending across the active regions and a pair of selection gates patterns that extend across the active regions and are interposed between the control gate patterns. A floating gate pattern is formed on intersection regions where the control gate patterns extend across the active regions. A lower gate pattern is formed on intersection regions where the selection gate patterns extend across the active regions. An inter-gate dielectric pattern is disposed between the control gate pattern and the floating gate pattern and a dummy dielectric pattern is disposed between the selection gate pattern and the lower gate pattern. The dummy dielectric pattern is substantially parallel to the selection gate pattern, and self-aligned with one sidewall of the selection gate pattern to overlap a predetermine width of the selection gate pattern.

Provided is a semiconductor device that includes first and second isolation patterns disposed on a substrate. Alternately stacked interlayer insulating patterns and a conductive patterns are disposed on a surface of the substrate between the first and second isolation patterns. A support pattern penetrates the conductive patterns and the interlayer insulating patterns and has a smaller width than the first and second isolation patterns. First and second vertical structures are disposed between the first isolation and the support pattern and penetrate the conductive patterns and the interlayer insulating patterns. A second vertical structure is disposed between the second isolation pattern and the support pattern and penetrates the conductive patterns and the interlayer insulating patterns. A distance between top and bottom surfaces of the support pattern is greater than a distance between a bottom surface of the support pattern and the surface of the substrate.

In multiple-layered memory devices, memory systems employing the same, and methods of forming such devices, a second memory device layer on a first memory device layer comprises a second substrate including a second memory cell region. The second substrate includes only a single well in the second memory cell region, the single well of the second memory cell region comprising a semiconducting material doped with impurity of one of a first type and second type. The single well defines an active region in the second memory cell region of the second substrate. Multiple second cell strings are arranged on the second substrate in the second active region. Although the second memory cell region includes only a single well, during a programming or erase operation of the memory cells of the second layer, requiring a high voltage to be applied to the single well in the substrate of the second layer, the high voltage will not interfere with the operation of the peripheral transistors of the first layer, second layer, or other layers, since they are isolated from each other. As a result, the substrate of the second layer can be prepared to have a thinner profile, and with fewer processing steps, resulting in devices with higher-density, greater reliability, and reduced fabrication costs.

An integrated circuit device is formed by forming a resistor pattern on a substrate. An interlayer dielectric layer is formed on the resistor pattern. The interlayer dielectric layer is patterned to form at least one opening that exposes the resistor pattern. A plug pattern is formed that fills the at least one opening and the plug pattern and resistor pattern are formed using a same material.
