    摘要: Nonvolatile memory devices include a string of nonvolatile memory cells on a substrate. This string of nonvolatile memory cells includes a first vertical stack of nonvolatile memory cells on the substrate and a string selection transistor on the first vertical stack of nonvolatile memory cells. A second vertical stack of nonvolatile memory cells is also provided on the substrate and a ground selection transistor is provided on the second vertical stack of nonvolatile memory cells. This second vertical stack of nonvolatile memory cells is provided adjacent the first vertical stack of nonvolatile memory cells. A conjunction doped semiconductor region is provided in the substrate. This conjunction doped region electrically connects the first vertical stack of nonvolatile memory cells in series with the second vertical stack of nonvolatile memory cells so that these stacks can operate as a single NAND-type string of memory cells.

    摘要: Methods of forming nonvolatile memory devices include forming a vertical stack of nonvolatile memory cells on a substrate. This is done by forming a vertical stack of spaced-apart gate electrodes on a first sidewall of a vertical silicon active layer and treating a second sidewall of the vertical silicon active layer in order to reduce crystalline defects within the active layer and/or reduce interface trap densities therein. This treating can include exposing the second sidewall with an oxidizing species that converts a surface of the second sidewall into a silicon dioxide passivation layer. A buried insulating pattern may also be formed directly on the silicon dioxide passivation layer.

    摘要: Memory devices include a stack of interleaved conductive patterns and insulating patterns disposed on a substrate. A semiconductor pattern passes through the stack of conductive patterns and insulating patterns to contact the substrate, the semiconductor pattern having a graded grain size distribution wherein a mean grain size in a first portion of the semiconductor pattern proximate the substrate is less than a mean grain size in a second portion of the semiconductor pattern further removed from the substrate. The graded grain size distribution may be achieved, for example, by partial laser annealing.
