    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.
