Abstract
Provided are a semiconductor memory device including a capacitor and a method of fabricating the same. The capacitor may include a plurality of contacts that are electrically connected to the switching device, exposed on the top surface of a substrate, and are arranged in a first direction and a second direction different from the first direction, and the first direction and the second direction are parallel to the substrate; mold insulators that are formed on the substrate between the contacts adjacent to one another in the first direction from among the plurality of contacts, are formed to have a predetermined thickness and have a predetermined width in the second direction, and extend in a direction vertical to the substrate; bottom electrodes that have a vertical plate-like structure, are provided on and supported by sidewalls of the mold insulators, and are electrically and respectively connected to the plurality of contacts.
