    摘要: A phase-change memory comprises a bottom electrode formed on a substrate. A first isolation layer is formed on the bottom electrode. A top electrode is formed on the isolation layer. A first phase-change material is formed in the first isolation layer, wherein the top electrode and the bottom electrode are electrically connected via the first phase-change material. Since the phase-change material can have a diameter less than the resolution limit of the photolithography process, an operating current for a state conversion of the phase-change material pattern may be reduced so as to decrease a power dissipation of the phase-change memory device.

    摘要: Phase change memory devices and fabrication methods thereof. A phase change memory device comprises a stacked heating element with a conductive portion and a relatively high resistive portion, wherein the relatively high resistive portion includes a nitrogen-containing metal silicide part. The heating stacked element such as a highly resistive nitrogen-containing metal silicide (MSixNy) is formed by a self-aligned silicidizing and nitrifying process. Self-aligned silicidization can be achieved by nitrogen ion implantation or nitrogen-containing plasma treatment. The resistance of the heating element can be regulated by adjusting the content of nitrogen or degree of nitrification.

    摘要: A phase change memory device and fabricating method are provided. A disk-shaped phase change layer is buried within the insulating material. A center via and ring via are formed by a lithography. The center via is located in the center of the phase change layer and passes through the phase change layer, and the ring via takes the center via as a center. A heating electrode within the center via performs Joule heating of the phase change layer, and the contact area between the phase change layer and the heating electrode is reduced by controlling the thickness of the phase change layer. Furthermore, a second electrode within the ring via dissipates the heat transmitted to the contact interface between the phase change layers, so as to avoid transmitting the heat to the etching boundary at the periphery of the phase change layer.
