Abstract
A fabricated multiple layer integrated circuit in which adequate planarization is accomplished using irregularly shaped and properly spaced conductive filler features that are spaced in such a way that capacitive coupling of the conductive filler features with the active conductive regions is reduced. The overall layout area of the conductive filler features is reduced to thereby reduced capacitive coupling with active conductive above and below. In addition, a relatively small edge of the feature is closest to the active conductive in the same conductive layer thereby further reducing capacitive coupling.
