    摘要: A sacrificial pattern is formed to partially cover the pipe-shaped electrode. A sacrificial spacer is formed on a lateral surface of the sacrificial pattern. The sacrificial spacer extends across the pipe-shaped electrode. The sacrificial spacer has a first side and a second side opposite the first side. The sacrificial pattern is removed to expose the pipe-shaped electrode proximal to the first and second sides of the sacrificial spacer. The pipe-shaped electrode exposed on both sides of the sacrificial spacer may be primarily trimmed. The pipe-shaped electrode is retained under the sacrificial spacer to form a first portion, and a second portion facing the first portion. The second portion of the pipe-shaped electrode is secondarily trimmed. The sacrificial spacer is removed to expose the first portion of the pipe-shaped electrode. A data storage plug is formed on the first portion of the pipe-shaped electrode.

    摘要: A phase-change memory device includes a word line on a substrate and a phase-change memory cell on the word line and comprising a phase-change material pattern. The device also includes a non-uniform conductivity layer pattern comprising a conductive region on the phase-change material pattern and a non-conductive region contiguous therewith. The device further includes a bit line on the conductive region of the non-uniform conductivity layer pattern. In some embodiments, the phase-change memory cell may further include a diode on the word line, a heating electrode on the diode and wherein the phase-change material layer is disposed on the heating electrode. An ohmic contact layer and a contact plug may be disposed between the diode and the heating electrode.
