Abstract
A de-coupling capacitor module using dummy conductive elements in an integrated circuit is disclosed. The de-coupling module comprises at least one circuit module having one or more active nodes, and at least one dummy conductive element unconnected to any active node, and separated from a high voltage conductor or a low voltage conductor by an insulation region to provide a de-coupling capacitance.

A de-coupling capacitor module in an integrated circuit comprising:
- at least one circuit module having one or more active nodes;
- and
- at least one dummy conductive element unconnected to any active node, and separated from a high voltage conductor or a low voltage conductor by an insulation region to provide a de-coupling capacitance.
A de-coupling capacitor module in an integrated circuit comprising:
- at least one circuit module having one or more active nodes;
- one or more dummy conductive elements unconnected to any active node;
- and
- one or more high voltage conductor or a low voltage conductor separated by an insulation region from at least one of the dummy conductive elements to provide a de-coupling capacitance,
- wherein the dummy conductive elements are substantially parallel among themselves and located in an area unoccupied by one or more circuit components connected to the active nodes.
A method for forming decoupling capacitors in a circuit comprising:
- forming one or more active nodes of an active circuit module;
- forming one or more metal structures substantially parallel to each other in one or more unused areas that are not connected to any active node of the active circuit module;
- and
- placing one or more contacts to connect the one or more metal structures to either a power supply voltage level or a ground level for forming the de-coupling capacitors.
