Abstract
The specification describes a thin film Integrated Passive Device (IPD) design that achieves isolation between conductive runners by shielding the top and bottom regions of a noisy runner with metal shield plates. The shield plates are derived from metal interconnect layers. The invention can be implemented by merely modifying the mask pattern for the metal interconnect layers. No added elements or steps are needed to fabricate the IPDs. The invention is suitable for use in Multi-Chip Modules (MCMs) or other arrangements where digital circuits and RF circuits are in close proximity.
