    摘要: In a method of manufacturing an MRAM device, a memory unit including a lower electrode, an MTJ structure and an upper electrode sequentially stacked is formed on a substrate. A protective layer structure including a capping layer, a sacrificial layer and an etch stop layer sequentially stacked is formed on the substrate to cover the memory unit. An insulating interlayer is formed on the protective layer structure. The insulating interlayer is formed to form an opening exposing the protective layer structure. The exposed protective layer structure is partially removed to expose the upper electrode. A wiring is formed on the exposed upper electrode to fill the opening.

    摘要: The present invention relates to the field of a semiconductor device having a ferroelectric material capacitor and method of making the same. The semiconductor device includes a capacitor having a triple-level oxygen barrier layer pattern formed by an oxygen barrier metal layer, a material layer formed of a conductive solid solution by compounding the oxygen barrier metal layer and oxygen, and an oxygen barrier metal on an interlayer dielectric with a contact plug. The capacitor also has an electrode and a ferroelectric film electrically contacting to the oxygen barrier layer.Further, a wetting layer is formed between the oxygen barrier layer and the contact plug, and an iridium oxygen layer is formed between the oxygen barrier layer and a capacitor electrode.

    摘要: There are provided PRAMS having a plurality of active regions located vertically in sequence and methods of forming the same. The PRAM and the method provide an approach to rapidly changing phase in a phase change layer pattern with a given design rule. A semiconductor substrate defining at least one reference active region is prepared in a cell array region and a peripheral circuit region. Other semiconductor substrates on a vertical line passing a main surface of the reference active region are located in sequence. The other semiconductor substrates define other active regions, respectively. A lower cell gate pattern is formed on the semiconductor substrate of the reference active region, and upper cell gate patterns are disposed on the other semiconductor substrates of the other active regions, respectively.
