    摘要: Magnetic memory devices, electronic systems and memory cards including the same, methods of manufacturing the same, and methods of forming perpendicular magnetic films are provided. The magnetic memory device may include a seed pattern on a substrate having a first crystal structure, a perpendicular magnetic pattern on the seed pattern having a second crystal structure, and an interlayer pattern between the seed pattern and the perpendicular magnetic pattern. The interlayer pattern may reduce a stress caused by a difference between horizontal lattice constants of the first and the second crystal structures.

    摘要: A magnetic memory device may include a free magnetic structure and a reference magnetic structure that are separated from each other by a tunnel barrier. The free magnetic structure may include an exchange-coupling layer, and first and second free layers that are separated from each other by the exchange-coupling layer. The first free layer may be provided between the second free layer and the tunnel barrier. A thickness of the first free layer may be greater than a first maximum anisotropy thickness, being the thickness at which the first free layer has maximum perpendicular anisotropy. A thickness of the second free layer may be smaller than a second maximum anisotropy thickness, being the thickness at which the second free layer has maximum perpendicular anisotropy. A magnetic tunnel junction having two free layers with different thicknesses can enable a magnetic memory device that has increased MR ratio and reduced switching current.

    摘要: Provided is a method of crystallizing an amorphous silicon thin film transistor and a method of fabricating a polycrystalline thin film transistor using the same, in which the polycrystalline thin film transistor indicating leakage current characteristics of a level that is applicable for active matrix organic light emitting diode displays (AMOLEDs) can be manufactured by using a silicide seed induced lateral crystallization (SILC) method. The amorphous silicon thin film transistor crystallizing method includes the steps of: forming an amorphous silicon layer on a substrate; forming an active region by patterning the amorphous silicon layer; forming a crystallization induced metal layer in both a source region and a drain region that are placed on both side ends of the active region; forming a number of dot-shaped metal silicide seeds on the surfaces of the source region and the drain region made of amorphous silicon by removing the crystallization induced metal layer; and crystallizing the active region formed of the amorphous silicon layer by heat-treating the substrate by using the metal silicide seeds as crystallization seeds.
