    摘要: A method for manufacturing a phase change memory device comprises forming an electrode layer. Electrodes are made in the electrode layer using conductor fill techniques that are also used inter-layer conductors for metallization layers, in order to improve process scaling with shrinking critical dimensions for metallization layers. The electrode layer is made by forming a multi-layer dielectric layer on a substrate, etching the multi-layer dielectric layer to form vias for electrode members contacting circuitry below, forming insulating spacers on the vias, etching through a top layer in the multi-layer dielectric layer to form trenches between the insulating spacers for electrode members contacting circuitry above, filling the vias and trenches with a conductive material using the metallization process. Thin film bridges of memory material are formed over the electrode layer.

    摘要: A phase change random access memory PCRAM device is described suitable for use in large-scale integrated circuits. An exemplary memory device has a pipe-shaped first electrode formed from a first electrode layer on a sidewall of a sidewall support structure. A sidewall spacer insulating member is formed from a first oxide layer and a second, “L-shaped,” electrode is formed on the insulating member. An electrical contact is connected to the horizontal portion of the second electrode. A bridge of memory material extends from a top surface of the first electrode to a top surface of the second electrode across a top surface of the sidewall spacer insulating member.
