    摘要: The annealing process at 400° C. or more required for the wiring process for a phase change memory has posed the problem in that the crystal grains in a chalcogenide material grow in an oblique direction to cause voids in a storage layer. The voids, in turn, cause peeling due to a decrease in adhesion, variations in resistance due to improper contact with a plug, and other undesirable events. After the chalcogenide material has been formed in an amorphous phase, post-annealing is conducted to form a (111)-oriented and columnarly structured face-centered cubic. This is further followed by high-temperature annealing to form a columnar, hexagonal closest-packed crystal. Use of this procedure makes it possible to suppress the growth of inclined crystal grains that causes voids, since crystal grains are formed in a direction perpendicular to the surface of an associated substrate.

    摘要: With a high-speed nonvolatile phase change memory, reliability in respect of the number of refresh times is enhanced. In a memory cell forming area of a phase change memory using a MISFET as a transistor for selection of memory cells, a phase change material layer of a memory cell comprising a resistor element, using a phase change material, is formed for common use. As a result, variation in shape and a change in composition of the phase change material, caused by isolation of memory cell elements by etching, are reduced, thereby enhancing reliability of memory cells, in respect of the number of refresh times.
