    摘要: Nonvolatile memory devices include a tunnel insulating layer on a substrate and a charge storing layer on the tunnel insulating layer. A charge transfer blocking layer is provided on the charge storing layer. The charge transfer blocking layer is formed as a composite of multiple layers, which include a first oxide layer having a thickness of about 1 Å to about 10 Å. This first oxide layer is formed directly on the charge storing layer. The charge transfer blocking layer includes a first dielectric layer on the first oxide layer. The charge transfer blocking layer also includes a second oxide layer on the first dielectric layer and a second dielectric layer on the second oxide layer. The first and second dielectric layers have a higher dielectric constant relative to the first and second oxide layers, respectively. The memory cell includes an electrically conductive electrode on the charge transfer blocking layer.

    摘要: A device includes a first GSL, a plurality of first word lines, a first SSL, a plurality of first insulation layer patterns, and a first channel. The first GSL, the first word lines, and the first SSL are spaced apart from each other on a substrate in a first direction perpendicular to a top surface of a substrate. The first insulation layer patterns are between the first GSL, the first word lines and the first SSL. The first channel on the top surface of the substrate extends in the first direction through the first GSL, the first word lines, the first SSL, and the first insulation layer patterns, and has a thickness thinner at a portion thereof adjacent to the first SSL than at portions thereof adjacent to the first insulation layer patterns.

    摘要: A gate of a transistor includes a gate oxide layer formed on a semiconductor device, a first conductive layer pattern including polysilicon doped with boron and formed on the gate oxide layer, a diffusion preventing layer pattern including amorphous silicon formed by a chemical vapor deposition process using a reaction gas having trisilane (Si3H8) and formed on the first conductive layer pattern, and a second conductive layer pattern including metal silicide and formed on the diffusion preventing layer pattern. Since a gate of PMOS transistor includes a diffusion preventing layer having an excellent surface morphology, diffusion of impurities is sufficiently prevented. Thus, the threshold voltage of PMOS transistor may be reduced and threshold voltage distribution may be improved.
