    摘要: A phase change memory device and method of manufacturing the same is provided. A first electrode having a first surface is provided on a substrate. A second electrode having a second surface at a different level from the first surface is on the substrate. The second electrode may be spaced apart from the first electrode. A third electrode may be formed corresponding to the first electrode. A fourth electrode may be formed corresponding to the second electrode. A first phase change pattern may be interposed between the first surface and the third electrode. A second phase change pattern may be interposed between the second surface and the fourth electrode. Upper surfaces of the first and second phase change patterns may be on the same plane.

    摘要: In a semiconductor memory device and a method of manufacturing the same, an insulating layer is formed on a substrate having a logic region on which a first pad is provided and a cell region on which a second pad and a lower electrode are subsequently provided. The insulating layer is etched to be a first insulating layer pattern having a first opening exposing the first pad. A first plug is formed in the first opening. The first insulating layer pattern where the first plug is formed is etched to be a second insulating layer pattern having a second opening exposing the lower electrode. A second plug including a phase-changeable material is formed in the second opening. A conductive wire and an upper electrode are formed on the first plug and the second plug, respectively.

    摘要: Provided are methods of forming contact structures and semiconductor devices fabricated using the contact structures. The formation of a contact structure can include forming a first molding pattern on a substrate, forming an insulating layer to cover at least a sidewall of the first molding pattern, forming a second molding pattern to cover a sidewall of the insulating layer and spaced apart from the first molding pattern, removing a portion of the insulating layer between the first and second molding patterns to form a hole, and forming an insulating pattern between the first and second molding patterns, and forming a contact pattern in the hole.
