    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: In a method of forming a diode, a first amorphous thin film doped with first impurities is formed on a single crystalline substrate. A second amorphous thin film doped with second impurities is formed on the first amorphous thin film. A laser beam having sufficient energy to melt both of the first and second amorphous thin films is irradiated on the first and second amorphous thin films to change crystal structures of the first and second amorphous thin films using the single crystalline substrate as a seed, so that first and second single crystalline thin films are sequentially formed on the single crystalline substrate.

    摘要: In some methods of fabricating a silicon-on-insulator substrate, a semiconductor substrate is provided that includes a single crystalline structure within at least a defined region thereof. A first insulating film is formed on the defined region of the semiconductor substrate with an opening that exposes a portion of the defined region of the semiconductor substrate having the single crystalline structure. A first non-single crystalline film is formed on the exposed portion of the semiconductor substrate and that at least substantially fills the opening in the first insulating film. A laser beam is generated that heats the first non-single crystalline film to change the first non-single crystalline film into a first single crystalline film having substantially the same single crystalline structure as the defined region of the semiconductor substrate.

    摘要: A method of forming a fin field effect transistor on a semiconductor substrate includes forming an active region in the substrate, forming an epitaxial layer on the active region, and removing a portion of the epitaxial layer to form a vertical fin on the active region. The fin has a width that is narrower than a width of the active region. Removing a portion of the epitaxial layer may include oxidizing a surface of the epitaxial layer and then removing the oxidized surface of the epitaxial layer to decrease the width of the fin. The epitaxial layer may be doped in situ before removing a portion of the epitaxial layer. The method further includes forming a conductive layer on a top surface and on sidewalls of the fin. Related transistors are also discussed.
