    摘要: A phase-change memory device includes a substrate having a contact region, an insulating interlayer on the substrate, a lower electrode electrically connected to the contact region, a phase-change material layer pattern formed on the lower electrode, and an upper electrode formed on the phase-change material layer pattern. The phase-change material layer pattern includes a chalcogenide compound doped with carbon and at least one of nitrogen and metal. The phase-change memory device may have a considerably reduced driving current without increasing a set resistance thereof. Further, the phase-change material layer pattern may have an increased crystallization temperature so as to ensure improved data retention characteristics of the phase-change memory device.

    摘要: In a method of forming a chalcogenide compound target, a first powder including germanium carbide or germanium is prepared, and a second powder including antimony carbide or antimony is prepared. A third powder including tellurium carbide or tellurium is prepared. A powder mixture is formed by mixing the first to the third powders. After a shaped is formed body by molding the powder mixture. The chalcogenide compound target is obtained by sintering the powder mixture. The chalcogenide compound target may include a chalcogenide compound that contains carbon and metal, or carbon, metal and nitrogen considering contents of carbon, metal and nitrogen, so that a phase-change material layer formed using the chalcogenide compound target may stable phase transition, enhanced crystallized temperature and increased resistance. A phase-change memory device including the phase-change material layer may have reduced set resistance and driving current while improving durability and sensing margin.

    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.
