Abstract:
1. A de-coupling capacitor module in an integrated circuit comprising: a plurality of circuit modules having one or more active nodes; a plurality of dummy conductive elements unconnected to any active node; a high voltage conductor between two of the dummy conductive elements which have a voltage lower than the high voltage conductor, the high voltage conductor separated by an insulation region from each of the two dummy conductive elements to provide a first de-coupling capacitance; and a low voltage conductor between another two of the dummy conductive elements having a voltage higher than the low voltage conductor and separated by a further insulation region from each of the other two dummy conductive elements to provide a second de-coupling capacitance, wherein the dummy conductive elements are substantially parallel among themselves, the dummy conductive elements being located outside of an area occupied by the circuit modules, so that none of the dummy conductive elements overlie or underlie any of the circuit modules having active nodes.
