Abstract

A semiconductor device includes a lower electrode structure, an upper electrode structure, and a dielectric layer between the lower and upper electrode structures and on side surfaces and an upper surface of the lower electrode structure. The lower electrode structure includes a first lower electrode pattern having a cylindrical shape, a barrier layer on the first lower electrode pattern, and a second lower electrode pattern in a space defined by the barrier layer.
