    摘要: In a method of manufacturing a semiconductor device, a string structure including a selection transistor and a memory cell on a substrate. An insulation layer pattern is formed on the substrate to cover the string structure. The insulation layer pattern includes at least one opening exposing a portion of the substrate adjacent to the selection transistor. A seed layer including a single-crystalline material is formed in the opening. An amorphous thin film including an amorphous material is formed on the insulation layer pattern and the seed layer. The amorphous thin film is transformed into a single-crystalline thin film, using the single-crystalline material in the seed layer as a seed during a phase transition of the amorphous thin film, to form a channel layer on the insulation layer pattern and the seed layer. Therefore, the semiconductor device including the channel layer having the single-crystalline thin film may be manufactured.

    摘要: Methods for forming semiconductor devices are provided. A semiconductor substrate is etched such that the semiconductor substrate defines a trench and a preliminary active pattern. The trench has a floor and a sidewall. An insulating layer is provided on the floor and the sidewall of the trench and a spacer is formed on the insulating layer such that the spacer is on the sidewall of the trench and on a portion of the floor of the trench. The insulating layer is removed on the floor of the trench and beneath the spacer such that a portion of the floor of the trench is at least partially exposed, the spacer is spaced apart from the floor of the trench and a portion of the preliminary active pattern is partially exposed. A portion of the exposed portion of the preliminary active pattern is partially removed to provide an active pattern that defines a recessed portion beneath the spacer. A buried insulating layer is formed in the recessed portion of the active pattern. Related devices are also provided.

    摘要: In a method of forming a single crystalline semiconductor layer, an amorphous layer may be formed on a seed layer that includes a single crystalline material. The single crystalline layer may be formed from the amorphous layer by irradiating a laser beam onto the amorphous layer using the seed layer as a seed for a phase change of the amorphous layer. The laser beam may have an energy for melting the amorphous layer, and the laser beam may be irradiated onto the amorphous layer without generating a superimposedly irradiated region of the amorphous layer. The single crystalline layer may include a high density of large-sized grains without generating a protrusion thereon through a simple process so that a semiconductor device including the single crystalline layer may have a high degree of integration and improved electrical characteristics.
