THREE-DIMENSIONAL CAPACITOR AND TOPOLOGICAL DESIGN METHOD FOR SUCH A CAPACITOR

摘要

A three-dimensional capacitor is formed from a multilayer of superposed electrodes. The electrodes are formed within respective metallization levels of an integrated circuit. At least two additional superposed electrodes are formed on top of the multilayer. Each additional electrode is formed from a branched rectilinear structure including at least one bar aligned in a first direction and a plurality of branches extending from that at least one bar in a second direction.
