    摘要: Semiconductor devices and methods of forming the same may be provided. The semiconductor devices may include gate patterns and insulation patterns repeatedly and alternatingly stacked on a substrate. The semiconductor devices may also include a through region penetrating the gate patterns and the insulation patterns. The semiconductor devices may further include a channel structure extending from the substrate through the through region. The channel structure may include a first channel pattern having a first shape. The first channel pattern may include a first semiconductor region on a sidewall of a portion of the through region, and a buried pattern dividing the first semiconductor region. The channel structure may also include a second channel pattern having a second shape. The second channel pattern may include a second semiconductor region in the through region. A grain size of the second semiconductor region may be larger than that of the first semiconductor region.

    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.

    摘要: A semiconductor memory device includes a semiconductor substrate, a tunnel insulating layer, charge trap layer, and a blocking layer. The tunnel insulating layer is on the semiconductor substrate. The charge trap layer is on the tunnel insulating layer and includes at least one pair of a first nitride layer with a higher trap density of holes than electrons and a second nitride layer with a higher trap density of electrons than holes. The blocking layer is on the charge trap layer opposite to the tunnel insulating layer. The first nitride layer may include silicon rich nitride, which may have a ratio of silicon to nitride of greater than 1 and less than or equal to 2. The second nitride layer may include aluminum nitride which may have a hexagonal crystalline structure.
