    摘要: A method of manufacturing the semiconductor device includes sequentially forming first to third mold layer patterns on a substrate and spaced apart from each other, forming a first semiconductor pattern between the first mold layer pattern and the second mold layer pattern, and a second semiconductor pattern between the second mold layer pattern and the third mold layer pattern, forming a first trench between the first mold layer pattern and the third mold layer pattern by removing a portion of the second mold layer pattern and portions of the first and second semiconductor patterns, depositing a material for a lower electrode conformally along side and bottom surfaces of the first trench, and forming first and second lower electrodes separated from each other on the first and second semiconductor patterns, respectively, by removing a portion of the material for a lower electrode positioned on the second mold layer pattern.

    摘要: Provided are methods of fabricating a semiconductor device including a phase change layer. Methods may include forming a dielectric layer on a substrate, forming an opening in the dielectric layer and depositing, on the substrate having the opening, a phase change layer that contains an element that lowers a process temperature of a thermal treatment process to a temperature that is lower than a melting point of the phase change layer. Methods may include migrating a portion of the phase change layer from outside the opening, into the opening by the thermal treatment process that includes the process temperature that is lower than the melting point of the phase change layer.
