Abstract

A method of fabricating a capacitor on a semiconductor substrate. A barrier layer is formed over the substrate to serve as a bottom electrode of the capacitor. A dielectric layer is formed on the barrier layer. An upper electrode is formed on the dielectric layer. In addition, the method can be used in a dynamic random access memory.
