Abstract
Various on-chip capacitors and methods of making the same are disclosed. In one aspect, a method of manufacturing a capacitor is provided that includes forming a first conductor structure on a semiconductor chip and forming a passivation structure on the first conductor structure. An under bump metallization structure is formed on the passivation structure. The under bump metallization structure overlaps at least a portion of the first conductor structure to provide a capacitor.
