Method of fabricating interconnect of capacitor

摘要

A method of fabricating an interconnect of a capacitor. A substrate having a capacitor is provided. The capacitor comprises a bottom electrode electrically connected to the substrate, a dielectric layer and a top electrode thereon. A spin-on dielectric layer is formed on the substrate and the capacitor. The spin-on dielectric layer on the substrate is thicker than that on the top electrode. The spin-on dielectric layer is etched back until the top electrode is exposed. A patterned metal layer is formed on the spin-on dielectric layer and the top electrode with a bottom surface in directly contact with a top surface of the top electrode.
