Abstract

Upon a deep-hole capacitor fabrication, a hole is formed in an insulator layer, and then a film of a conductive material is formed on the insulator layer and on the whole inner surface of the hole. The film and the insulator layer are exposed to a chemical-mechanical polishing process to form a lower electrodes of the conductive material. A capacitor dielectric on the lower electrode is formed, and then an upper electrode is formed on the capacitor dielectric.
