Abstract

A capacitor and method of manufacturing the same include an insulating interlayer, a lower electrode, a protection structure, a dielectric layer and an upper electrode. The insulating interlayer may include a conductive pattern formed on a substrate. The lower electrode may be electrically connected to the conductive pattern. The protection structure may be formed on an outer sidewall of the cylindrical lower electrode and on the insulating interlayer.
