Abstract
The present disclosure discloses a manufacturing method of a memory device including forming a structure including an epitaxial material plug extending vertically on a substrate, an epitaxial material layer extending horizontally from a side surface of the epitaxial material plug, and a gate insulating material layer formed at least on a surface of the epitaxial material layer, defining a transistor including a word line by forming the word line in contact with the gate insulating material layer in a transistor formation region around the epitaxial material plug in the structure, removing the epitaxial material layer and the gate insulating material layer from a capacitor formation region adjacent to the transistor formation region of the structure, and forming a capacitor connected to one end of the epitaxial material layer corresponding to a channel of the transistor.
