    摘要: A vertical memory device may include a substrate, a first selection line on the substrate, a plurality of word lines on the first selection line, a second selection line on the plurality of word lines, and a semiconductor channel. The first selection line may be between the plurality of word lines and the substrate, and the plurality of word lines may be between the first and second selection lines. Moreover, the first and second selection lines and the plurality of word lines may be spaced apart in a direction perpendicular with respect to a surface of the substrate. The semiconductor channel may extend away from the surface of the substrate adjacent sidewalls of the first and second selection lines and the plurality of word lines. In addition, portions of the semiconductor channel adjacent the second selection line may be doped with indium and/or gallium. Related methods are also discussed.

    摘要: In an embodiment, a method of manufacturing a charge-trapping dielectric and a silicon-oxide-nitride-oxide-silicon (SONOS)-type non-volatile semiconductor device includes forming the charge-trapping dielectric, and a first oxide layer including silicon oxide. A silicon nitride layer including silicon-rich nitride is formed by a cyclic chemical vapor deposition (CVD) process using a silicon source material and a nitrogen source gas. A second oxide layer is formed on the silicon nitride layer. Hence, the charge-trapping dielectric having good erase characteristics is formed. In the SONOS-type non-volatile semiconductor device including the charge-trapping dielectric, a data erase process may be stably performed.

    摘要: According to example embodiments, a vertical type semiconductor device includes a pillar structure on a substrate. The pillar structure includes a semiconductor pattern and a channel pattern. The semiconductor pattern includes an impurity region. A first word line structure faces the channel pattern and is horizontally extended while surrounding the pillar structure. A second word line structure has one side facing the impurity region of the semiconductor pattern and another side facing the substrate. A common source line is provided at a substrate portion adjacent to a sidewall end portion of the second word line structure.
