    摘要: Since a chalcogenide material has low adhesion to a silicon oxide film, there is a problem in that it tends to separate from the film during the manufacturing step of a phase change memory. In addition, since the chalcogenide material has to be heated to its melting point or higher during resetting (amorphization) of the phase change memory, there is a problem of requiring extremely large rewriting current. An interfacial layer comprising an extremely thin insulator or semiconductor having the function as both an adhesive layer and a high resistance layer (thermal resistance layer) is inserted between chalcogenide material layer/interlayer insulative film and between chalcogenide material layer/plug.

    摘要: Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.

    摘要: A semiconductor non volatile memory device capable of multiple write operations with high reliability includes memory cells. Each memory cell of the device has a first electrode, a second electrode, and an information storage section between the two electrodes. A segregation of composing elements of the information storage section caused by applying a first current pulse from the first electrode to the second electrode is corrected by applying a second current pulse from the second electrode to the first electrode such that the composition of the storage section recovers to its original state.
