    摘要: A magnetic device and a method of manufacturing the same. In the method, a lower magnetic layer, an insulation layer, and an upper magnetic layer are sequentially formed on a substrate. An upper magnetic layer pattern is formed by patterning the upper magnetic layer until an upper surface of the insulation layer is exposed. An isolation layer pattern is formed from portions of the insulation layer and the lower magnetic layer by performing an oxidation process on the exposed upper surface of the insulation layer, and an insulation layer pattern and a lower magnetic layer pattern are formed from portions of the insulation layer and the lower magnetic layer, where the isolation layer pattern is not formed.

    摘要: A method of forming a phase change material layer pattern includes forming a phase change material layer partially filling an opening through an insulating interlayer. A plasma treatment process is performed on the phase change material layer to remove an oxide layer on a surface of the phase change material layer. A heat treatment process is performed on the phase change material layer to remove a void or a seam in the phase change material layer, sufficiently filling the opening.

    摘要: Provided is a method of forming a semiconductor memory cell in which in order to store two bits or more data in a memory cell, three or more bottom electrode contacts (BECs) and phase-change materials (GST) have a parallel structure on a single contact plug (CP) and set resistances are changed depending on thicknesses (S), lengths (L) or resistivities (ρ) of the three or more bottom electrode contacts, so that a reset resistance and three different set resistances enable data other than in set and reset states to be stored. Also, a method of forming a memory cell in which three or more phase-change materials (GST) have a parallel structure on a single bottom electrode contact, and the phase-change materials have different set resistances depending on composition ratio or type, so that four or more different resistances can be implemented is provided.

    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.
