    摘要： A first lower interconnection structure and a second lower interconnection structure are formed using a first design rule on a first region of a substrate and a second region of the substrate, respectively. A memory element is formed on the first lower interconnection structure. The memory element includes a bottom electrode, a magnetic tunnel junction and a top electrode stacked on each other. An upper conductive line and an upper interconnection line are formed using a second design rule larger than the first design rule on the first lower interconnection structure and the second lower interconnection structure, respectively. The first lower interconnection structure, the memory element and the upper conductive line are stacked on each other so that the memory element is interposed between the first lower interconnection structure and the upper conductive line.

    摘要： A semiconductor device includes an active region defining an isolation region. First and second cell interconnection structures are on the active region and the isolation region, and have line shapes that are parallel to each other. An isolation pattern is on the active region and the isolation region. The isolation pattern is between the first and second cell interconnection structures. Contact structures are between the first and second cell interconnection structures. The contact structures are at both sides of the isolation pattern and overlap the active region. Insulating patterns are between the first and second cell interconnection structures. The insulating patterns are at both sides of the isolation pattern and overlap the isolation region. Common source regions are under the first and second cell interconnection structures. The common source regions are in the active region. An isolating gate pattern that has a line shape is under the isolation pattern.

    摘要： Magnetic memory devices are provided. A magnetic memory device includes a Magnetic Tunnel Junction (MTJ) structure on a contact. Moreover, the magnetic memory device includes an insulating structure and an electrode between the MTJ structure and the contact. In some embodiments, a first contact area of the electrode with the MTJ structure is smaller than a second contact area of the insulating structure with the MTJ structure.

    摘要： Disclosed is a method for manufacturing a magnetic memory device. The method for manufacturing a magnetic memory device comprises sequentially forming a first magnetic layer, a tunnel barrier layer, and a second magnetic layer on a substrate, forming a boron absorption layer on the second magnetic layer, sequentially forming a metal capping layer and an oxygen donor layer on the boron absorption layer, and performing a heat treatment process to diffuse at least a portion of oxygen atoms included in the oxygen donor layer into the metal capping layer and the boron absorption layer. The metal capping layer has a greater oxygen diffusivity than the oxygen donor layer.
